"The Fukushima Daiichi nuclear power plant in Japan emitted a new burst of radioactive material this week after a bungled cooling effort apparently affected spent atomic fuel in the site's No. 4 reactor cooling pond, the Associated Press reported."
"Workers were firing water into the pond from a distance in an effort to prevent the fuel from overheating and releasing radioactive contaminants, but fluid collecting in an adjacent flood control container triggered an incorrect warning that the pond had been filled. Personnel halted water transfers to the pool for a number of days in response to the warning, allowing heat and radiation levels to increase even though the fuel was thought to have remained submerged, Japanese Nuclear and Industrial Safety Agency Deputy Director General Hidehiko Nishiyama said. Water spraying began again on Wednesday."

Inadequate spent fuel water levels would NOT affect the reactor. Two separate systems. The reactor was defueled, hence the reactor is not an issue. The spent fuel pool is NOT the reactor. Thanks.
ReplyDeleteMy oversight. It was the sfp at that temp. thanks
