Small Reactors Make a Bid to Revive Nuclear Power

Can small, LEGO-like reactors help create better prospects for the nuclear industry?















Share on Tumblr

But the Department of Energy funding may only support two designs. Innovation spurred by competition seems unlikely. And that may ultimately erode the current U.S. nuclear industry advantage—from design to operation to regulation.

That means that the rest of the world—particularly China, which is building almost every type of reactor on offer, and Russia—may well inherit the promise and peril of nuclear power, whether small or large. "China and India lead the world in nuclear safety today," NRG CEO David Crane told the Bloomberg New Energy Finance Summit on March 20. NRG initiated and abandoned plans to build at least two new large reactors in the last five years, thanks to falling natural gas prices and uncertainty surrounding U.S. government policy. "The U.S. cannot lead the world in safety, if we're not building new nuclear power plants."

    An idiot is someone who does the same thing over and over an expect a different result. Since they seem hell-bent and determined to frack the shell rock for natural gas, and the only thing you can do with it is burn it, why don't they use natural gas to heat water that would turn turbines? About 20 turbines in one plant can generate enough power to power 170 million homes and businesses, and you wouldn't have to worry about finding a place to store nuclear waste, which this article said it would be deadly for about 250,000 years and natural gas shouldn't be as polluting as oil and coal or nuclear.

    An idiot is someone who says the same idiotic things over and over no matter how many times they have been destroyed in argument.

    "...why don't they use natural gas..."

    Uh, duh, because there isn't nearly enough NG to replace Coal or Oil or even to meet rising Energy Demand. And your Shale Gas has just as much GHG emissions as Coal, including Methane Leakage. And Radiation emissions from Shale Gas exceed anything Nuclear Power ever dreamed of.

    "..have to worry about .. place to store nuclear waste,..would be deadly for about 250,000 years.."

    Yep, instead you just dump the one million times greater amount of waste, including Radon & other Radioisotopes, NOx, SOx, deadly fine particulates which lodge inside a persons lung sacs, CO2, methane @ 75X the GHG potential of CO2, into the Air, onto the Land and into the Water for people to eat, drink & breath. James Davis figures that's OK. Nuclear is the ONLY energy source that contains its wastes.

    As for the "250,000 yrs" disinformation statement, well that is a lot less than the forever that James Davis' Coal Waste, Oil & Gas waste last, including deadly heavy metals that build up in the environment. Let's take an honest and scientific look at "Nuclear Waste", from someone who actually knows about it - not some idiot he just repeats Big Oil propaganda:

    "...One immediate application of Fig. 1 is to estimate how much of the waste glass, converted into digestible form, would have a good chance of killing a person who eats it — this may be called a "lethal dose." We calculate it by simply dividing the quantity of waste glass, l5 tons, by the values given by the curve in Fig. 1, and the results are as follows:
    Shortly after burial 0.01 oz.
    After 100 years 0.1 oz.
    After 600 years 1 oz.
    After 20,000 years 1 lb.

    Lethal doses for some common chemicals are as follows11:
    selenium compounds 0.01 oz.
    potassium cyanide 0.02 oz.
    arsenic trioxide 0.1 oz.
    copper 0.7 oz. ..."

    www.phyast.pitt.edu/~blc/book/chapter11.html

    So after 600 yrs, Nuclear Waste is LESS DEADLY THAN COPPER!

    As an example of James Davis' "I'm Ok with that" non-Nuclear waste - the Canadian gov't is going to freeze in place, right on the shores of Great Slave Lake - 240,000 tonnes of carcinogenic, poisonous Arsenic Trioxide, which will have to be maintained FOREVER. CANDU nuclear waste has the same radiation level as natural Uranium after 500 yrs. And that spent fuel replaced 2.4 billion tonnes of CO2 emissions, so 6X the total Spent Fuel in Canada. Just for some residue from one mickey-mouse Gold Mine.

    "...age of terrorism I wonder, even if buried, how secure these are going to be..."

    Yeah, like terrorists are going to rent giant front-end loaders, kill off all personnel, kill off the police who will be on site in about 30 mins max, spend the about 10 hrs it will take to dig up UG reactor, if they were VERY,VERY lucky and some how break threw the steal and concrete containment and WOWEE they got access to a soccer ball or less sized chunk of highly radioactive core material, kinda like medical isotopes or agricultural/industrial/geophysical/security radioisotopes that exist all over the world. Except much harder to utilize for any nefarious purpose.

    I would say it would be about 10,000X easier to blow up any of the 10's of thousands of miles of deadly NG pipelines, a lot of which are rusted out and ready to explode anyway, or chlorine storage or cyanide or peroxides or acids shipped all over in rail cars, or use a submersible to attach anti-tank mines (Iran has lots) to blowout preventers & undersea oil & gas pipelines in the Gulf of Mexico and blow them open all at once by remote control. Or maybe just hijack an Airbus 380 and crash it into a LNG storage facility or hijack and LNG tanker and blow it up in New York harbor. Or Canada & Alberta's big multi-$billion CCS SCAM to greenwash the Tar Sands - with blanket 100% liabiltiy protection on CO2 releases. With thousands of kms of liquid CO2 pipelines being a Terrorist's dream-come-true. Yep smother a whole city. Notice Greenpeace & the Sierra Club never complain about that Terrorist risk.

    Terrorism & SMR's - nope, pure hype.

    I think technology, safety and nuclear waste are solvable. The main turnoff to nuclear is cost. The article mentioned a cost of $7/watt for large reactors and higher for small reactors. That's pretty steep. You can probably build a coal or gas plant for $2/watt.

    "There is no inherent reason why nuclear power needs to be expensive," Bill Gates, who has invested in the novel reactor proposed by TerraPower, told the ARPA–e summit on February 28, noting that nuclear's relative expense largely derives from building in safety features."

    Arguments about nuclear power aside... I'm a little concerned that Bill Gates is investing in nuclear power. The above quote does not alleviate my concerns, not one little bit... nada, nope. Now, I'm thinking I understand how Windows Vista got released. After all, there's no reason an operating system needs to be expensive, noting that most of the cost is associated with, you know, making it work. Now, if we could just get an opensource nuclear reactor ;)

    How genuine are those who claim that nuclear is unsafe. Even the two Japanese cities that were bombed with atomic bombs are now & have been for decades, heavily populated. The only nuclear accident that has ever resulted in radiation deaths was Chernobyl & the death toll there was less than one hundred. Those who have wished for heavy death tolls from nuclear accidents have been sadly disappointed & still try to claim that the danger still lingers. Just in China the annual death toll in coal mines is about three thousand.

    It is sickening that some people only talk about the danger of nuclear radiation in Japan while ignoring the real death toll from the tsunami.
    That is so similar to the arguments about pollution, global warming & Co2 being such a dire threat while arguing against nuclear power, thus perpetuating all the things they are campaigning against. Many would prefer the death of mankind instead of real solutions & they often admit it.

    If the billions wasted on solar wind & wave had been spent on nuclear research, building demonstration plants to test several of the most promising technologies, perhaps by now some of them would be reaching sufficient maturity to begin mass installation. Unfortunately it takes many years to properly test a new system. These experimental systems need to be built now but we can not wait for the proving period. Reactors using existing technology are a vastly superior option to building coal fired power stations.

    4 meters wide by 25 meters tall (no mention of the length) does not seem small to me. I am not even sure a rail car could handle something that tall. The center of gravity would have to be near the bottom for sure. Why can't they build something smaller than that? Like big enough to power a neighborhood instead of a medium size city.

    I know they have nuclear power on some of the space probes. I admit that the power requirements in space would be very small but we should be able to build something smaller than the ones described in this article that could contain much smaller amounts of nuclear material and be much safer. Oh... never mind. That would make it to easy for communities to opt out of the power companies controls and would hurt the big utilities.

    The main constraint on buliding new nuclear reactors is that the more that are built the sooner uranium ores will be depleted. Reactors are built to last thirty years, the same period of time for total uranium ore depletion. So building new reactors is just not economical, it is the poor old tax payer will end up paying through the nose for decommissioning.

    yeah I think ARPA-e is doing the right thing by neglecting funding for things like this and focusing on other items. Personally I look around and the most obvious and efficient power sinks are plant life which also happen to utilize the most plentiful energy source around - the sun - and convert that energy in the most efficient way known to man. It seems just a matter of time before we harnous plant life in an environmentally friendly way to feed our energy needs. And the best way to make that happen quickly is to create more scientists. And the best way to create more scientists is to reduce the costs of higher education. It does seem many of our problems would be best solved by not helping ourselves but by helping our children. But unfortunately that's counter to the 1%ers and the American political philosophy. So I guess we will just continue to throw money at the problem and hope for instantaneus results... Gamble.

    The 1998 World Health Organization (WHO) study claimed 212 deaths over 12 years from the 72,000 workers who cleaned up Chernobyl and exposed themselves to high radiation. This death toll figure was endorsed by the environmental activist group Greenpeace. This translates to 0.025% mortality rate for this high-risk population.

    Note that the average mortality rate in the US is 0.84% according the CIA Factbook (2012). The average American is more likely to die than the Chernobyl clean-up workers.

    According to the National Cancer Registry of Ukraine, from 1989 to 2006 the highest incidence of thyroid cancer in the country was 0.001% for males and 0.005% for females.

    Now compare that to the thyroid cancer incidence in the US according to the World Health Organization (WHO) 0.005% for males and 0.015% for females. The average American male and female are 5 times and 3 times more likely to develop thyroid cancer than Ukrainians who live near Chernobyl.

    As for environmental impact, Chernobyl is open to tourists. The radiation level in the contaminated areas is lower (9 mSv) than the natural radiation in Norway (11 mSv).

There has been NO discernible increase in cancer rates attributable to the accident at Chernobyl. The Chernobyl accident occurred on April 26, 1986. That is thirty six years ago.

    @eco-steve

    This is pretty misleading. There happens to be quite a bit of uranium in seawater, which would raise the cost of fuel somewhat, but would not significantly affect the current economics of nuclear power.

    But I do not think that is the best way to go. As conventional LWR only consumes U-235 and some bred Pu, fast reactors would be far more fuel efficient, allowing them to operate for thousands of years.

    What would be far better though is to take that U, enrich it to 20%, and then use that to start a molten salt thorium-fueled reactor. Thorium has a cleaner fuel cycle, and the molten salt reactors do not require a great deal of initialization fissile, allowing for rapid expansion. The high temperature of operation allows for both dry cooling and efficient energy-carrier (H2, NH3, etc.) synthesis.

    The downside is that the technology has to be aggressively developed, and the general populace remains incredibly ignorant of both the precarious situation we are in and the importance of cheap energy for maintaining the economy. We risk losing civilization if we do not promptly act with prudence.

    The reactor, called a Hyperion Power Module (HPM), is designed to be used as the energy source for small base load power stations. Euphemistically referred to as a "fission battery" the HPM is transportable on the back of a truck and each HPM reactor supplies enough energy to power more than 25,000+ large homes, or the equivalent, for 10 years. It is not refueled on site. After the non-weapons grade fuel has run its course, the sealed 1.5 metre wide by 2.5 metres tall canister is replaced with another and the original is returned to the factory. No spent or ‘waste' fuel is stored at the site. Features and operating procedures including these and others have made the HPM attractive globally as a non-proliferation nuclear energy solution.

    Low levels of radiation are not dangerous and may give protection against cancer in later life. see www.radiationandreason.com Current limits could be raised by a factor of 200 without any danger. People in Iran and France are living healthy lives in radiation levels comparable to the highest levels experienced at Fukushima. Fukushima has not, and will not, kill anyone from radiation sickness.

    At $7000/kW nuclear power is a lit cheaper than solar power that costs ~$4000/ kW because you need 4000 MW of solar to equal 1000MW of nuclear. So the equivalent cost is $16,000/kW. And that is without transmission and backup. Solar power is seriously crazy.

    WRONG! Solar PV generates RETAIL electricity at the point of load, so your arbitratry multiplication of its costs is just silly. It reduces bottlenecks in transmission by effectively taking load centers off the grid during peak demand (either partly or completely providing the electricity needs of the structures it sits on).

    Solar module costs have dropped %50 over the last 2 years and are still falling. Balance-of-system component costs are falling as well. (don't know what balance-of-system is? If not, WHY ARE YOU COMMENTING ON THIS ISSUE IN SUCH A STATE OF IGNORANCE?) The main thing holding Solar PV back now is the hostile attitude directed against it by local governments (red tape, permitting issues), homeowners associations (NIMBYism) and the illogical hatred from people like you and members in congress that are likewise just as ignorant.

    Sault: I am not wrong.

    Solar on houses generates retail electricity only for some of the time. Solar farms are often far from the load. Solar power stops when the sun sets and drops by 40-60% when there is a cloud over the sun. Conventional power stations and the transmission and distribution system are needed to maintain a continuous supply.

    All this costs money and all consumers pay for it. So the solar power subsidies are largely paid by poor people to benefit the rich.

    Disgraceful.

    If you want to move away from generating CO2 - event though it doesn't cause dangerous global warming, then nuclear power is safer than any other major form of power generation and effective in reducing CO2.

    The costs you are showing are EIA (always extreme optimists for Fossil Fuel), and DO NOT include Fuel costs. So of course CCGT is a much lower Capital Cost than large PWR's, using typical construction methods, under the current Onerous Regulatory Environment.

    The killer with Natural Gas is Fuel Cost. With Nuclear Fuel cost 1/4 to 1/2 cent per kwh, and Natural Gas is 2 to 3 cents per kwh at current bargain basement North American NG prices. Fuel cost is more like 10-12 cents per kwh at Asian prices - and you're a fool if you think these low NG prices will last. Start replacing Coal, and new demand with NG, as well as exporting LNG and NG transportation and see how long NG prices are low. Shale Gas is mostly hype, produces a lot for a short time, then the field becomes uneconomical at even modest NG prices.

    And then there is the cost of NG infrastructure, including storage. It is in a state of decay, just repairing the current NG infrastructure will cost 100's of $billions, never mind adding new infrastructure. Cost of new NG infrastructure will certainly add 2-3 cents per kwh to NG generation cost.

    And the fact is, there isn't nearly enough NG to replace Coal, or even to meet new demand for energy worldwide, and it is very expensive & dangerous to transport, and the real cost will be way too high to support developing nation economies.

    There really is ONLY one viable replacement for fossil fuels, and that is Nuclear. Asian capital costs for Nuclear are running less than CCGT, including the necessary NG infrastructure.

    It is very important to understand that Nuclear is a CLASS of Energy, like Renewables are and Fossil Fuel is, so saying Nuclear costs X$ a kw is like saying Fossil Fuel costs X$ a kw or Renewable Energy costs X$ a kw. As-a-matter-of-fact, the Nuclear Class of Energy is much bigger than either the Fossil Fuel or Renewables class. There are literally hundreds of very different designs for Nuclear Power. We haven't even began to exploit the potential for Nuclear energy. There are dirt cheap methods to produce Nuclear.

    Example, David Leblanc's denatured molten salt reactor, factory produced on an assembly line, with standardized, no-nonsense licensing, certain to be a lower cost than ANY Fossil Fuel or Renewables tech.

    The ONLY real obstacle to low cost Nuclear is the current total apathy of politicians to replacing Fossil Fuels. When it comes to Peak Oil or Climate change, some Politicians talk-the-talk, but don't walk-the-walk.

    Actually the real cost of first of kind nuke power in the US is $4B/ Gw the cost of the new reactors at VC Summer in the south. The Vogtle in Georgia cost for the nukes is the same but the total project includes an additional $4B for upgrades of the state's transmission network.

    For nuclear costs at the mature end of the learning year we have costs of less than 3 cents a kwh after the first score of Candu's were built. Here is an example of units 26 and 27 of Candu technology.all on time in 4 years and on budget at $2B/Gw or less than 3 cents a kwh.- the cheapest reactor available anywhere outside China. The last one was completed in 2007 in Europe.

    Google cnnc 168 candu

    Westinghouse now 90% finished building the first AP-1000 at Saimen in China on time and on budget estimates the cost of new AP-1000's at $2B/Gw as factory production now under way in China moves into full gear.

    Again, if you think anything with the "Made in China" label is built to the proper standards %100 of the time like nuclear technology NEEDS to be, you're crazy. Besides, the low-ball reactor costs in China are that low because of currency manipulation, hidden subsidies, horrible worker pay, horrible working conditions and the fact that China's government can never really separate itself from its economy in any way.

    VC summer is actually $4.5B per GW and that is too low because they get to charge their ratepayers $1.4B before the plant even cranks out one electron. How come we can't have a feed-in tariff like that for renewables in this country? The track record of building renewable energy in the U.S. is stellar compared to the dozens of reactor construction failures that caused the nuclear industry to implode in the 1980s. Efficiency and renewables are MUCH lower-risk investments of ratepayers' and taxpayers' money compared to the billions that have been flushed down the nuclear toilet in the past.

    Oh, and these plants are getting loan guarantees from the government, lowering their capital costs even further while the Price Anderson Act allows the nuclear industry to have its liability insurance covered by the feds FOR FREE! If nuclear technology was so great, why does it need all this interference from the government 60 years after it was developed? I can understand support for renewable energy that is just now entering the market, but why does a technology developed for the Manhattan Project need such huge government crutches to stand on its own?

    So Ole Sault is at it again. With his laughable claim of a BS and MS in engineering, he continues to spew his many times debunked repeated horsepucky on nuke power in his effort to retain his stupidest commenter on Sciam title.

    The Vogtle/Summer twin AP-1000 reactor now 90% complete on time on budget at half the cost in China, is an American design build by American engineers under the watchful eye of NRC observers. The Chinese were so concerned about nuke safety after FUKU that they halted approval on all nuke projects for a year. If FUKU had happened in China, the corrupt managers would have all been executed and their body parts harvested ensuring great attention to safety. The Chinese reactors are built by public power so have no incentives to cut corners. Chinese reactors are built by engineers and craftmen - American ones by attorneys doubling American costs.

    Once again we see Sault can't do elementary arithmetic. The actual number is $4.18B/Gw for a first of a kind reactor. Westinghouse claims after the first score or so of these reactor are built factory module production will cut that cost in half similar to the Chinese experience.

    The cost of most renewables are paid 100% by the taxpayer up front by tax credits, unsecured loan guarantees and grants. The advance actually reduces the cost to rate payers significantly as the extremely inefficient American private utility is forced to borrow from Wall Street pirates at rates approaching 15%. Had Public power TVA borrowing at 2% built those machines the cost would be insignificant.

    Since the last 7 Candu's were all built on time and on budget all over the world up to 2007 and the 4 AP-1000's under construction in China are all more than 75% complete on time and on budget, it would appear that unlike day care employee Sault, the industry has learned a lot in the last thirty years. One difference is all AP-1000's/Candu's are all built exactly the same as opposed to the earlier 60's design's every one different.

    The only one proposed American loan guarantee at Vogtle is appearing to be so onerous the Vogtle is considered turning it down.

    The nuke industry carries $15B in an insurance fund that will never be used as the chances of the Fuku accident under a modern and onerous NRC regulation is exactly zero. No other Bhopal chemical or Big Oil nuke bomb sized LNG terrist targets carry even a tiny fraction of that insurance. Like asteroid hits and alien invasions insurance companies can't insure against events that would bankrupt them - no matter how unlikely.

    Small nuclear power unit manufacture would resemble airliner manufacturing. Each unit of a fixed design would be low enough in cost that one could be sacrificed to actual safety testing to demonstrate the safety of the hundreds which are just like it. Certification testing would be much superior to the present scheme of relying on computer analysis on one of a kind builds. Who would buy a ticket on a plane if our only assurance that the wings won't fall off is a computer printout for a condition never actually tested?

    That's a good point. And having a regulator of SMR's that is separate from the NRC and modeled after the FAA. The NRC is dysfunctional monster bureaucracy that was setup specifically to block Nuclear Power.

    Notice the difference between the NRC and the FAA:

    The FAA's major roles include:

    "Encouraging and developing civil aeronautics, including new aviation technology."

    A role that is sadly absent in the lets-kill-as-many-people-as-possible-due-to-Coal-Pollution NRC.

    Notice bilateral agreements:

    www.faa.gov/aircraft/air_cert/international/bilateral_agreements/

    So an aircraft is tested and approved by the EU then it will be approved by the FAA. Including the Airbus 380 targetable flying Nuclear Bomb sized weapon. The Airbus 380 initially failed to meet its vital 150% wing strength certification test, the engineers immediately modified the wing design, and the plane was certified 45 days later in both the USA & Europe. The NRC would send the design team back to the drawing board for 5 yrs worth of redesign and paid-by-Airbus training of NRC personal @ $273 per hour - including bureaucrats who wouldn't be able to repair a flat bicycle tire.

    atomicinsights.com/2011/12/examples-of-regulatory-costs-for-nuclear-energy-development.html

    So the CANDU which can burn American LWR nuclear spent fuel and does in China, run on thorium and is station-blackout Fukushima type accident immune. And approved and operating in a dozen countries as well as Canada with a very tough regulator. To get those same CANDUs approved by the NRC would cost $100's of millions and take probably 5-15 yrs. Despicable regulatory madness. The GenIII CANDU:

    And FAA supplemental type certificates for Foreign designed aircraft:

    Canada was ahead of the Rest of the World, with the Slowpoke III, 10 MWth reactor, 600 kwe. Intrinsically safe based on TRISO (pebble bed) fuel, runs 3 yrs @ 10MWth on one fueling. Fuel load can be carried on one plane. Cost $10M or $1k per kwth, way cheaper than Oil, suitable for heat & power for small Northern Communities and Mining Camps which rely on expensive, job killing, smoke belching, terrorist funding Oil for most of their Energy. Also could have been used in fuel guzzling Ocean Shipping. Was earmarked for Canada's submarines. Unfortunately, the Slowpoke III was blocked by despicable pseudo-Greenies.

    In the EIA study, the fuel cost of CC is included in the O&M cost which is measured in MWhr. CC is still cheaper than nuclear.

    Oh, so is this the same "watchful eye" of the NRC that allows stuff like this to happen?

    "Federal regulators have been working closely with the nuclear power industry to keep the nation's aging reactors operating within safety standards by repeatedly weakening those standards, or simply failing to enforce them, an investigation by The Associated Press has found.

    Examples abound. When valves leaked, more leakage was allowed - up to 20 times the original limit. When rampant cracking caused radioactive leaks from steam generator tubing, an easier test of the tubes was devised, so plants could meet standards.

    Failed cables. Busted seals. Broken nozzles, clogged screens, cracked concrete, dented containers, corroded metals and rusty underground pipes - all of these and thousands of other problems linked to aging were uncovered in the AP's yearlong investigation. And all of them could escalate dangers in the event of an accident."

    http://www.pjstar.com/free/x1781765020/AP-study-U-S-nuclear-regulators-weaken-safety-rules

    Yeah, that's a really "watchful eye"!

    And all your blathering about how China would do things is pure, emotionally-charged conjecture on your part. "Public power" has no incentives to cut corners? Give me a break! So I guess these guys had no incentive to put melamine in pet food or cadmium in childrens' toys, right?

    Also, there are 2 reactors being constructed at Voglte and 2 reactors being build at VC Summer, so get your facts straight. And the construction permit at Vogtle was just approved in Feb 2012, so no, they AREN'T %90 finished either. Unit 3 will be online in 2016. How can we think that you're debating in good faith when you can't even tell us the facts? In the age of Google, why lie?

    Oh, and get this: "The federal government has awarded the project $8.3 billion in conditional federal loan guarantees, and Georgia Power's customers are paying down the financial costs of the project with a fee on monthly bills."

    http://www.ajc.com/business/groups-sue-to-stop-1351830.html

    Oh, and if you think CANDU reactors are so awesome, look at this:

    "Based on Ontario's record, the economic performance of the CANDU system is quite poor. Although much attention has been focussed on the problems with the Darlington plant, in fact, every single CANDU design in Ontario went over budget by at least 25%, and average over 150% higher than estimated.[58] Darlington was the worst offender, at 350% over budget, but this project was stopped in-progress thereby incurring additional interest charges during a period of high interest rates, which is a special situation that was not expected to repeat itself.

    In the 1980s, the pressure tubes in the Pickering A reactors were replaced ahead of design life due to unexpected deterioration caused by hydrogen embrittlement. Extensive inspection and maintenance has avoided this problem in later reactors.

    All the Pickering A and Bruce A reactors were shut down in 1999 in order to focus on restoring operational performance in the later generations at Pickering, Bruce and Darlington. Before restarting the Pickering A reactors, OPG undertook a limited refurbishment program. The original cost and time estimates based on inadequate project scope development were greatly below the actual time and cost and it was determined that Pickering Units 2 and 3 would not be restarted for commercial reasons. Despite this refurbishment, the reactors have not performed well since the restart.

    These overruns were repeated at Bruce, with Units 3 and 4 running 90% over budget.[58] Similar overruns were experienced at Point Lepreau,[59] and the planned refurbishment of the Gentilly 2 plant has been delayed until the fall of 2012, and currently there are serious plans to simply shut it down instead.[60]

    Based on the projected capital costs, and the low cost of fuel and in-service maintenance, in 1994 power from CANDU was predicted to be well under 5 cents/kWh.[61] In 1998, Ontario Hydro calculated that the cost of generation from CANDU was 7.7 cents/kWh, whereas hydropower was only 1.1 cents, and their coal-fired plants were 4.3 cents. As Hydro received a regulated price averaging 6.3 cents/kWh for power in this period, the revenues from the other forms of generation were being used to fund the operating losses of the nuclear plants."

    Continued...

    "The debt left over from the nuclear construction could not be included in the rate base until the reactors were declared in service, thereby exacerbating the total capital cost of construction with unpaid interest, at that time around $15 billion, and another $3.5 billion in debts throughout the system[62] was held by a separate entity and repaid through a standing charge on electricity bills.

    In 1999, Ontario Hydro was broken up and its generation facilities re-formed into Ontario Power Generation (OPG). In order to make the successor companies more attractive for private investors, $19.4 billion in "stranded debt" was placed in the control of the Ontario Electricity Financial Corporation. This debt is slowly paid down through a variety of sources, including a 0.7 cent/kWh tariff on all power, all income taxes paid by all operating companies, and all dividends paid by the OPG and Hydro One. Even with these sources of income, the amount of debt has grown on several occasions, and in 2010 stood at almost $15 billion. This is in spite of total payments on the order of $19 billion, ostensibly enough to have paid off the debt entirely if interest repayment requirements are ignored.[62]

    Darlington is currently in the process of considering a major re-build of several units, as it too is reaching its design mid-life time. The budget is currently estimated to be between $8.5 and $14 billion, and produce power at 6 to 8 cents/kWh. However, this prediction is based on three assumptions that appear to have never been met in operation: that the rebuild will be completed on-budget, that the system will operate at an average capacity utilization of 82%, and that the Ontario taxpayer will be on the hook for 100% of any cost overruns.[63] Although Darlington Units 1, 3 and 4 have operated with an average lifetime annual capacity factor of 85% and Unit 2 with a capacity factor of 78%,[64] refurbished units at Pickering and Bruce have lifteime capacity factors between 59 and 69%.[63] However, this includes periods of several years while the units were shut down for the retubing and refurbishing. In 2009, Bruce A Units 3 and 4 had capacity factors of 80.5% and 76.7% respectively, in a year when they had a major Vacuum Building outage.[65]"

    "..EIA study, the fuel cost of CC is included in the O&M cost which is measured in MWhr.."

    No it ain't. Are you kidding me? $3.37/Mwh for variable O&M including fuel - NO. If it does include fuel they will say including fuel:

    www.eia.gov/oiaf/aeo/electricity_generation.html

    So as you see variable O&M for CCGT including fuel as of Nov. 2010 is $45.6/Mwh - Not $3.37/MWh. And that is with UNBELIEVABLE RECORD LOW NG prices - which WILL NOT LAST. The Shale Gas Boom has been called the World's largest uneconomic investment and has frequently been compared to the last housing bubble fiasco.

    So yes Levelized Cost, according to the EIA, of fully mature assembly line built CCGT, along with extraordinary amounts of GHG emissions (including methane it is worse than Coal), and a NG price that is 1/4 to 1/5th International prices (how long can that last?) is indeed lower than First-of-a-kind GenIII PWR's with zero supply chain built, zero learning curve, zero flexibility of choice, zero factory builds, zero assembly-line production and almost zero competition.

    And also you have to add about 2 cents per kwh to NG for the NG infrastructure which is not including in the EIA pricing. Just one example of the new infrastructure necessary to supply future NG - Artic NG - the Mackenzie Valley pipeline to deliver 1200 MMCF/day or 15.1 GW of avg. thermal power.

    The Arctic NG supply reserves are estimated at 6 TCF, or 14 yrs supply for the pipeline.

    So overnight capital cost of the pipeline would be $1126 per kwt, with only 14 yr supply of fuel. So with a 50% efficient CCGT that's $2252 per kwe, so that alone will add a couple cents to fuel cost, with a production cost of minimum 3 cents per kwh you up to 5 cents per kwh fuel cost minimum.

    And remember it is INEVITABLE that that fuel cost will explode with future supply shortages, international pricing and Carbon Penalties. And that high cost will continue and rise above the rate of inflation for the ENTIRE 60-100 yr of the Nuclear Power plant. Whereas the Capital Cost of Nuclear will be paid off in 15-20yrs. And by-the-way they are using 7.4% interest, whereas public power companies can sell bonds @ 2% interest, and the Fed is giving away $trillions to private crooked screw-up banks @ 0% interest.

    So it is pretty damn obvious, take away the EXTRAORDINARY level of Big Carbon interference in the Free Market, doing their damnest to block Nuclear Power - it is quite obvious that rapid Nuclear Power expansion is a NO-BRAINER!

    Sault has sunk to a new low, pasting a full page of Wikipedia right into the comments, information that he doesn't understand and probably hasn't even bothered to read. Didn't even bother to properly quote the mass of text he posted without even the decency to say where he got all that.

    So many times I have explained the Cost Escalations of CANDU's in Ontario, which even government mandated reports have shown occurred due to political reasons, not intrinsic to the Reactor Build itself - and specifically recommended continuing the CANDU builds with qualifications.

    Typical reprehensible behavior of Sault, you explain these issues to him, in detail, he thereupon completely ignores the explanation, offers no counter whatsoever, and THEN JUST GOES AND REPEATS THE SAME DRIVEL OVER & OVER. The man doesn't have an ethical bone in his entire body.

    You have to take a Wikipedia article like the one Sault posted without any comprehension, with some skepticism and requires proper analysis. Just one example:

    "...generation from CANDU was 7.7 cents/kWh, whereas hydropower was only 1.1 cents, and their coal-fired plants were 4.3 cents.."

    This is entirely bogus, in 1998 including the capital cost or debt payments on the recently constructed Nuclear Plants (Darlington $14.4B 3.5GWe in 1993) with already paid off debt on the ancient Hydro and Coal plants. Note EIA puts O&M costs on Hydro at 1 cent per kwh - just as the 1.1 cent mentioned - so it is obviously just O&M cost quoted, which for Nuclear is 1.7 cents per kwh - EIA (2010).

    So the proper analysis, something Sault doesn't know how to do, would say capital cost on the most heavily inflated Darlington build was $14.4B in 1993 for 3.52 GWe. Capacity factors have been over 90%. That's $19.6B in $2010. So 19.6/3.52/.92 = $6k/kweavg. Not so bad eh Sault? Sault claims $13-$25k/kweavg for Wind is a good deal. And Solar at $20-80/kweavg is also a good deal.

    So most of what Sault posts, that he doesn't understand, is poorly researched information from Ontario Clean Air Alliance which believes Ontarians should pay 14-80 cents a kwh for nutty Solar & Wind Scams which do not produce useful power.

    Another example of Saults quoted misinformation - an actual proper analysis of the Ontario Debt Retirement charge, which concludes the Nuclear Debt is already paid off, and in actual fact the Ontario Gov't is funneling the DRC to Wind Energy.

    You are right and wrong. Right, $3.37/MWh doesn't include fuel. Wrong, nuclear is not cheaper. Your own reference shows total cost for nuclear is $113.9/MWh while for conventional combined cycle is $66.1/MWh.

    It is common knowledge in the power industry that nuclear is more expensive than conventional coal and gas plants. We can debate about the exact figures but it is generally true that nuclear is more expensive. Unless we include a carbon tax.

    The proper way to make nuclear energy is by Thorium. The Liquid Salt Thorium Reactor was initiated by Enrico Fermi of University of Chicago, a Nobel prize winner in physics no less. His work was continued by Alvin Weinberg and colleagues at Oak Ridge, Tennessee.

    This method cannot produce a nuclear bomb. it has 1% if that of the wastes of the Uranium and Plutonium reactors. The waste products are Strontium and Neodymium. These elements may have some background radiation but nothing compared to the wastes of the Light Water Reactors.

    It is incomprehensible that research on this topic was halted by the Nixon administration during the 1970s. There will be no Fukushimas, Chernobyls, Three Mile Islands nor Windscales of the UK, with this technology.

    The pebble bed reactor is a safe method. You can use Thorium, or even Neodymium as fuel. Both these elements can be coated with Carbon , like the South Africans did in the 1960s. This way you mechanically pile the fuel together, use hot gas, nitrogen perhaps, to drive turbines to generate electricity.

    Sure, politics caused hydrogen embrittlement on the fuel bundles and reactor structures in some of those plants, right? Politics likewise keeps Ontario's nuclear plants from getting above an %82 capacity factor, right? Give me a break! This technology is hugely expensive without even discussing the massively pricey heavy water plant needed to provide moderator / coolant for these reactors. And then it looks like most of them need a "mid-life refurbishment" costing billion$ more! What a deal!

    Please! Show me how politics caused these technical issues! I'll buy the fact that political pressure may have caused construction delays, but I have seen hardly ANY evidence to back that up. I have not seen EVEN ONE of your explanations that you have allegedly supplied "so many times".

    "Why Nuclear?” If you look at the chart at the top right of the slide below, SCANA provided their all-in cost estimates for nuclear ($76/MWh), natural gas ($81/MWh), coal ($117/MWh), offshore wind
    ($292/MWh) and solar ($437/MWh). For them, “new nuclear continues to be the low cost alternativ"

    And how many times do I have to tell you, YOU CAN'T TRUST THE PRICES FOR REACTORS BUILT IN CHINA! We can't just clear people off their land and make them deal with a nuclear plant in their backyard like they can in China. We can't have the government funnel billions of yuan either. I mean, the subsidies in the U.S. aren't a well-hidden, take the Price Anderson Act or Loan Guarantees or all those billions spent developing the LWR fuel cycle by government labs for the Manhattan Project, but I digress. Finally, in a market economy, the government can't just make nuclear reactors by fiat like the Chinese Government does. So, unless you're a big fan of Communism, you need to stop quoting baloney Chinese reactor costs like they're legitimate.

    P.S. Thanks for confirming my attitude towards personal insults in relation to the validity of someone's argument!

    You know, the hallmarks of a baseless conspiracy theory are always harsh allegations with ZERO evidence to back them up.

    So please, show me the evidence of "Big Oil" donating money to the White House to make the NRC anti-nuclear. (Whew, did I get all that straight?) How can this be if "Big Oil gives %88 of its political donations to Republicans?

    http://thinkprogress.org/green/2012/03/23/450941/will-senators-stand-up-for-american-consumers-or-big-oil/

    I've asked numerous times about the lawsuits or at least investigations into the NRC's supposedly anti-nuclear bias and you just retreat like a coward EVERY SINGLE TIME. Could it be that there ISN'T any evidence because nuclear proponents such as your self are just making it up?

    Additionally, how can the NRC be so anti-nuclear when they started issuing combined design and construction permits to speed up the approval process? Does that sound like an organization that wants to destroy the industry? Do you know how silly you sound?

    By the way, did you see THIS article:

    http://www.forbes.com/sites/jeffmcmahon/2012/03/29/exelons-nuclear-guy-no-new-nukes/

    “Let me state unequivocably that I’ve never met a nuclear plant I didn’t like,” said John Rowe, who retired 17 days ago as chairman and CEO of Exelon Corporation, which operates 22 nuclear power plants, more than any other utility in the United States.

    “Having said that, let me also state unequivocably that new ones don’t make any sense right now.”

    "I’m the nuclear guy,” Rowe said. “And you won’t get better results with nuclear. It just isn’t economic, and it’s not economic within a foreseeable time frame.”

    Rowe has been on a bandwagon of promoting NG power generation for the past several years, and has quietly admitted its all about putting cashy money in his pocket. For its Nuclear Generation Exelon gets paid the most expensive bid that NG power plants get - and with low NG prices now that is not very high. Rowe admits he want to return "that glorious period" of much higher NG prices 2004-08. Then, since Nuclear is a fixed cost, of about 1.5-2 cents per kwh, the higher NG price is - is CLEAR PROFIT. And ANY competitive Nuclear plants built will reduce NG price and reduce the value of Exelon's OWN low Carbon Electricity.

    As well Rowe has been campaigning for extreme controls on Coal Burning & Carbon Trading to once again reduce competition for his product. Rowe is a lawyer with ZERO TECH training or interest - his interest is ONE & ONLY ONE - making as much cash as possible. A carbon copy of Ken Lay of Enron who also promoted Carbon Trading and restrictions on new power generation. The New Capitalism: compete fairly in the free market & win by having the best product REPLACED by make sure YOU have the ONLY product in the marketplace by forcing out the competition by ANY MEANS possible - best of all - buying political influence, ENGO's & media. That is John Rowe / Ken Lay in a nutshell.

    "..show me the evidence of "Big Oil" donating money to the White House to make the NRC anti-nuclear.."

    Well, you need only look at the MMS, Minerals Management Service, which regulated Oil Drilling, in particular in the Gulf of Mexico. They accepted an emergency action plan for an Oil Spill that included saving the Walruses in the Gulf Of Mexico, and contacting long dead scientists. Zero requirement for Fail-Safe emergency shutdowns, which is industry standard EVERYWHERE EXCEPT in the Oil Industry. Batteries Fail - Too Bad, Hydraulic Pressure low - Too Bad, No communication with Oil Rig - Too Bad. And drug & sex parties with Big Oil execs and MMS management. And maximum 30 days Environmental hearings for getting a MEGA-OIL-SPILL Rig. No lawsuits allowed. Unlike Nuclear which is often stuck with 5 yrs of environmental hearings and NON-STOP lawsuits by ENGO's like the Sierra Club & Greenpeace.

    So tell us Sault, tell us that the MMS was NOT corrupted by Big Oil cash? Tell us how you believe that the MMS was a legitimate regulator? And if you admit that the MMS was corrupted by Big Oil, please tell us how you believe that Big Oil wouldn't go one step further, with their

    And if you admit that the MMS was corrupted by Big Oil, please tell us how you believe that Big Oil wouldn't go one step further, with their UNLIMITED CASH to corrupt the NRC, which by any logical analysis is more valuable to Big Oil than the MMS, simply by blocking Nuclear Power puts FAR more cash in Big Oil's pockets than ALL OF:

    a)the Iraq Oil war - who started that and why? - tell us Sault.

    b)unrestricted drilling in the Gulf of Mexico.

    c)unrestricted drilling in Alaska Federal lands etc.

    Follow the money dude. The current head of the NRC is a staunch anti-Nuke, who had ZERO qualifications for the job, a former puppy of the anti-Nuke nutcase - Ed Markey and then went to work for Harry "boondoggle" Reid, who thereupon threatened to shutdown the Federal Gov't if Bush wouldn't appoint Jackzo as NRC chief.

    Meanwhile, Shale Gas companies like Chesapeake Energy have been caught financing ENGO's like the Sierra Club to block Nuclear Power with non-stop lawsuits, as they have been doing. Just that one NG company funneled $25M into the Sierra Club to fund their anti-Nuclear and anti-Coal campaigns, with an agreement of $30M more, which the Sierra Club executive lied about until they got caught red handed, and consequently they refused to call Shale Gas the Environmental Disaster that it obviously is, and instead referred to NG as a "transition fuel". One of Sierra Clubs execs, a person with integrity, resigned from them, writing of her "disgust" of the cozy relationship of ENGOs with NG interests, biggest in North America being Exxon.

    Not a personal insult just a statement of fact.

    You are the one who claims an BS and MS (Bull S and More S) in engineering when in reality you work in daycare.

    How many times to I have to tell you. The AP-1000's are built in China. by American engineers to American standards with NRC observers. There is no advantage to building in Hitek China other than public power. You see any Chinese airliners flying around?

    No other country in the world has a Price Anderson yet nukes elsewhere have no insurance issues at all.

    Most of the US's hydro power was build by FDR's public power. TVA, Bonneville are far more efficient than the tiny pirate outfits like Excelon.

    The Slowpoke III, 10 MWth reactor, 600 kwe. Intrinsically safe based on TRISO (pebble bed) fuel, runs 3 yrs @ 10MWth on one fueling. So safe it was licensed for unattended operation, with remote monitoring. Fuel load can be carried on one plane. Cost $10M or $1k per kwth, way cheaper than Oil, suitable for heat & power for small Northern Communities and Mining Camps which rely on expensive, job killing, smoke belching, terrorist funding Oil for most of their Energy. Also could have been used in fuel guzzling Ocean Shipping. Was earmarked for Canada's submarines. Unfortunately, the Slowpoke III was blocked by despicable Greenies, who as usual try their damnest to maintain Big Oil's Energy Hegemony.

    The article mentions the need for the nuclear industry to make provision for compensation to sick or evacuated people in the event of a disaster.
    This fund exists in France, but for one reactor close to Paris the fund ammounts to one euro per person-equivalent fukushima victim. Enough said?

    How about some compensation for the millions KILLED by your fossil fuels and biomass burning smoke? How about for the 13,000 homes evacuated by one mud volcano caused by NG drilling, which will continue for 85 yrs? Or the towns in Germany evacuated PERMANENTLY by Giant Coal Strip Mines or the VAST AREAS evacuated permanently by giant Hydro dams.

    And the people killed and homes destroyed in NG explosions.

    And how about FORCING Greenies to pay for the cost of the Radiation Paranoia they deliberately & maliciously create - the disinformation they spread recklessly on Radiation health effects, that has ZERO basis in Radiation Health Physics. And forcing Greenie ENGOs to have full disclosure for the source of their $Billion in tax exempt funding. Why should the taxpayer be subsidizing Greenpeace etc, so they can KILL millions of persons by spreading disinformation, and REFUSE to disclose where there funding is coming from?

    I really don't know why Americans get so emotional about nuclear power. Is it:
    a) Because the French use it
    or
    b) Because there was a very minor nuclear power station accident in the USA and at about the same time there was a crappy B movie released about a nuclear meltdown.

    Makes me think of Orson W and his radio broadcast that caused a panic all over the US.
    More people are severely injured and die in ONE YEAR in the USA in chlorine escape incidents than have been severely injured or killed in the entire history of nuclear power in the USA ( ..and maybe western Europe and Japan combined).
    Grow up!

    "Of course, human error has yet to be eliminated from either operating reactors or those that exist only on paper." is a lie, as you should know. All of Generation 4 are intrinsically safe, relying only on Nature for safety. As you already said, spent fuel is fuel for Generation 4 Integral Fast Reactor. Read the book: "Prescription for the Planet" by Tom Blees, 2008; and read
    http://BraveNewClimate.com

    Reference: "The Rise of Nuclear Fear" by Spencer Weart. The fear started thousands or millions of years ago with the fear of witches, wizardry, magic etc. The design of the human brain is very bad. See "Religion Explained" by Pascal Boyer.

    "The Rise of Nuclear Fear" by Spencer Weart needs "Religion Explained" as background. A lot of modern first world people do magical thinking rather than logical or scientific thinking [not all logical thinking is scientific]. That is, they think of technology and things they don't understand as magic. That is especially true of anything "nuclear."

    The US government did a lot of propagandizing about nuclear things in the 1950s. Some US government officials used secrecy as an instrument of political power at the same time. The secret is:

    THERE ARE NO SECRETS.

    Nature is an open book. Nature is the same everywhere. Any country with enough money, sanity, scientists and uranium can make a nuclear bomb. Most that could, chose not to. Iran seems to be stuck by a lack of something cultural. Uranium is mineable in many countries.

    The following seems to be too complicated for many people:

    Bomb = bad
    Reactor = good

    There is no possible way that a reactor could ever become a nuclear bomb. Chernobyl did not. I will have to tell you a little about how to make a bomb to explain the difference. Nothing classified. See:

    dwbd, I agree with your arguments and I like your style...

    I agree with Rock in that I would like to see better development of Thorium based reactors. Thorium is about 3 times more abundant than Uranium and the breeding of Th into fissile U234 has minimal nuclear proliferation risks and does not produce the transuride isotopes that persist for so long in the environment. Finally, I would like to see development of molten salt nuclear reactors, whereby fuel could be added and waste removed on a more or less continuous basis. The U.S. began to develop this type of reactor in the 1950's at Oak Ridge National Laboratory but the project was discontinued in favor of light water reactors due to the lower initial cost. Now would be a good time to look at that method again.
