TOKYO (TR) – As much as 8.5 tons of radioactive cooling water escaped from Tokyo Electric Power Company’s Fukushima Daiichi reactor No. 4 after a pipe broke at the facility, Kyodo News reported, citing the power utility.
Engineers at the plant stopped the leak 13 minutes after the pipe burst and none of the radioactive water left the building, officials said, according to Kyodo. No fuel was in reactor No. 4 when the March 11, earthquake and tsunami hit; it was undergoing maintenance and offline at the time.
TEPCO suspects either recent cold weather or an explosion that occurred in the weeks after the initial disaster may have damaged the pipe, the news agency said.
