Damaged power cable briefly disables frozen soil shields at Fukushima No. 1

JIJI
JUL 29, 2015

FUKUSHIMA – Frozen soil shields aimed at curbing the buildup of radioactive water were temporarily disabled at Tokyo Electric Power Co.’s stricken Fukushima No. 1 nuclear power plant on Tuesday.

The problem occurred after a power cable was damaged by mistake, Tepco said.

Electricity leaked from the damaged cable, causing fail-safe systems to kick in for the shields and other devices, it said.

The underground shields, designed to block groundwater from flowing into the basements of the stricken reactor buildings, were restarted later in the day.

The power leak also halted a device circulating nitrogen in reactors 1, 2 and 3 to prevent hydrogen explosions.

According to Tepco, a plant worker found white smoke around the power cable at around 8:35 a.m.
