Soil shields disabled & nitrogen circulation halted at Fukushima

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

The Japan Times: July 29, 2015

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. […]

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 leakage also halted a device circulating nitrogen reactors1, 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.
