All cooling water is gone from the spent-fuel pool at one of the crippled nuclear reactors in Japan, causing the release of high levels of radiation, Gregory Jaczko, chairman of the U.S. Nuclear Regulatory Commission, told members of Congress.
Jaczko’s testimony followed warnings by the International Atomic Energy Agency, physicians and nuclear engineers that the greatest threat to public health from the damaged Fukushima nuclear plant is spent fuel in pools of water atop of the plant’s six reactors.
