Weekend Update on Japanese Nuclear Plants


Fusushima Daiichi:

Units 5 and 6 have reached cold shutdown.

Fire fighters have managed to spray large amounts of water into the spent fuel pools in Units 3 and 4. Pool temperatures in Units 1 – 4 are all below boiling. Seawater is being pumpd into the spect fuel pool on Unit 2. Circuit test ing underway prior to restoring power to the Unit 2 control room and planning for power lines to Units 3 and 4 in underway.

It appears that the Japanese now have the upper hand in dealing with this accidednt. In the end, it’s worse than TMI but an order of mangintude less severe than Chernobyl. It will be interesting to see the post mortem from this event.
