Grim news from American experts on the Fukushima nuclear plant:
Gregory Jaczko, the chairman of the commission, said in Congressional testimony that the commission believed that all the water in the spent fuel pool at the No. 4 reactor of the Fukushima Daiichi Nuclear Power Station had boiled dry, leaving fuel rods stored there completely exposed. As a result, he said, “We believe that radiation levels are extremely high, which could possibly impact the ability to take corrective measures.”
If his analysis is accurate and Japanese workers have been unable to keep the spent fuel at that inoperative reactor properly cooled covered with water at all times radiation could make it difficult not only to fix the problem at reactor No. 4, but to keep workers at the Daiichi complex from servicing any of the other crippled reactors at the plant.
