Fifty workers and fire hoses are all that remain at Japan's Fukushima I plant to cool three hot reactors and six pools containing spent fuel rods – perhaps for months to come.
Resolution of Japan's nuclear crisis hangs on the decisions – and actions – of about 50 remaining workers, laboring amid intense radioactivity and smoke, as they try to prevent the six-reactor Fukushima I plant from becoming a nuclear mess to rival the Chernobyl disaster, according to US nuclear experts monitoring the situation.
A spike in radioactivity at the site on Monday led authorities to send to safety most workers at the plant, which is 150 miles north of Tokyo. If the remaining few dozen personnel using just fire hoses are unable to keep three "hot" reactors – plus six pools containing spent fuel rods – cool, a meltdown would soon occur, these experts say. About 30 tons of water boil off the reactors each hour and must be replaced to prevent the reactor cores from melting down.
"This is definitely in the Chernobyl league now," says Frank von Hippel, a nuclear physicist at Princeton University. "If the reactors go, that's bad, of course. But the real concern at this point is if those ... spent-fuel pools catch fire. There are many Chernobyls' worth of radioactive material in there."
