U.S. nuclear plants use the same sort of pools to cool spent nuclear-fuel rods as the ones now in danger of spewing radiation at Japan's Fukushima Daiichi plant, only the U.S. pools hold much more nuclear material. That's raising the question of whether more spent fuel should be taken out of the pools at U.S. power plants to reduce risks.
The Japanese plant's pools are far from capacity, but still contain an enormous amount of radioactivity, Lyman said. A typical U.S. nuclear plant would have about 10 times as much fuel in its pools, he said.
The unfolding disaster at the Fukushima nuclear plant follows decades of falsified safety reports, fatal accidents and underestimated earthquake risk in Japan's atomic power industry.
The warnings were stark and issued repeatedly as far back as 1972: If the cooling systems ever failed at a “Mark 1” nuclear reactor, the primary containment vessel surrounding the reactor would probably burst as the fuel rods inside overheated. Dangerous radiation would spew into the environment.
According to Biff Bradley, the director of risk assessment for the Nuclear Energy Institute, it's almost impossible to try to rank the absolute safety risk of a plant, due to the number of variables that would be involved in any sort of direct comparison.
The number and strength of earthquakes in central Arkansas have noticeably dropped since the shutdown of two injection wells in the area, although a state researcher says it's too early to draw any conclusions.
The gung-ho nuclear industry is in deep shock. Just as it and its cheerleader, the International Atomic Energy Agency, were preparing to mark next month's 25th anniversary of the Chernobyl accident with a series of self-congratulatory statements about the dawning of a safe age of clean atomic power, a series of catastrophic but entirely avoidable accidents take place in not one but three reactors in one of the richest countries of the world. Fukushima is not a rotting old power plant in a failed state manned by half-trained kids, but supposedly one of the safest stations in one of the most safety-conscious countries with the best engineers and technologists in the world.
When Congress considered whether to regulate more closely the handling of wastes from oil and gas drilling in the 1980s, it turned to the Environmental Protection Agency to research the matter. E.P.A. researchers concluded that some of the drillers’ waste was hazardous and should be tightly controlled.
