The crippled Fukushima Daiichi power plant in northeastern Japan hit by another blow as the system to cool the nuclear reactor and fuel pool has stopped at its No. 5 unit, said Tokyo Electric Power Co (TEPCO) on Sunday.
TEPCO had started work to repair the cooling facility hoping to restore the system within several hours, said an official. He said that the collapse of the cooling systems would not cause any rapid rise in temperatures at the reactor and spent fuel pool, Reuters reported.
After the devastating March 11 earthquake and tsunami, the Fukushima Daiichi plant's No. 1 to 4 reactors were severely damaged. However, both the No. 5 and No. 6 reactors faced less sever damages.
