TEPCO partially restores power to cooling systems at Fukushima plant

TOKYO — Engineers at the crippled Fukushima Daiichi nuclear plant partially succeeded Tuesday in restarting cooling systems after a power cut underlined its still-precarious state two years after a tsunami struck.

Equipment in pools used to keep used fuel cool—necessary to prevent any spontaneous nuclear reactions—lost their power supply at 6:57 p.m. on Monday, operator TEPCO said.

By late Tuesday, two of the cooling systems were back up, reports said. One other was likely to be online later in the day, the company said earlier.
