Breaking news continues to focus on the six compromised reactors at Japan's Fukushima Daiichi nuclear power complex. But authorities have shut down eight other reactors in the region that were affected by last week's earthquake. Forty more units continue to operate across the nation. The map above, released by the Japan Atomic Industrial Forum, shows the status of every reactor as of March 17.

The industrial forum is now releasing detailed updates about the crippled reactors once or twice a day.
