TOKYO -(Dow Jones)- Tokyo Electric Power Co. (9501.TO) said Friday most of the detectors lying below the pressure vessel at the No. 1 reactor of the crippled Fukushima Daiichi nuclear power plant that check the condition of the control rods have been found damaged, Kyodo News reported Friday.

 TEPCO  said Friday most of the detectors lying below the pressure vessel at the No. 1 reactor of the crippled Fukushima Daiichi nuclear power plant that check the condition of the control rods have been found damaged.

The damage – mostly burnt wiring or electrical shortages – is believed to have been caused by the intense heat in the wake of a core meltdown.

The utility conducted current tests on the detectors, which each cover 97 control rods, and found only one detector functioned normally, it said.


Junichi Matsumoto, a senior official at the utility, said he believes the detectors suffered such damage as both pressure and temperatures exceeded the given design limits for the pressure vessel.
