Tokyo Electric Says Cooling Pump Started at Fukushima Plant’s No.5 Reactor
Tokyo Electric Power Co. said it restarted the residual-heat removal pump at the No. 5 reactor of its stricken Fukushima Dai-Ichi nuclear plant, one of the least damaged at the facility.
The utility began cooling the pool in the reactor that contains spent fuel rods, it said in a statement today. Temperatures in the pool had earlier fallen to 67.6 degrees Celsius from 68.8 degrees, Kyodo News reported. Temperatures should be kept below 25 degrees Celsius, according to international guidelines.
The No. 5 reactor was one of three that were offline and undergoing maintenance when the plant was crippled by the March 11 earthquake and tsunami. Firefighters and troops are spraying sea water on the No. 1, 2, 3 and 4 reactors, which suffered more damage and may pose a greater risk of radiation leaks.
