That cooling strategy, while essential to prevent full meltdowns, has released harmful amounts of radioactive steam into the atmosphere and set off leaks of highly contaminated water, making it perilous for some of the hundreds of workers at the plant to further critical repair work.

One major problem, said Murray E. Jennex, an associate professor at San Diego State University with 20 years of experience in examining nuclear containment structures, was that all the water the Japanese were spraying had soaked important machinery like generators and pumps, further hampering efforts to restore the reactors’ electricity supply
