TOKYO (TR) – Water temperature in the No. 2 reactor at Tokyo Electric and Power Company’s damaged Fukushima Daiichi nuclear power plant has risen 25 degrees since January 27, Japan’s NHK News said, citing the electric utility.
The temperature was last reported at 70 degrees Celsius after hovering recently at around 45 degrees. Only one thermometer in the reactor is showing the rise; two other heat monitoring devices are unchanged, NHK reported.
TEPCO has been unable to pinpoint the cause of the temperature rise. The utility said plumbing work done in late January at the plant may be to blame.
Tokyo Electric has increased the amount of cooling water it normally injects into the reactor to cool the nuclear fuel. That effort so far has failed to show any results, NKH said.
