The cooling system of the third reactor at the Fukushima nuclear power plant has stopped circulating water following a powerful 7.3 offshore earthquake. TEPCO said it managed to restart the system some 90 minutes after the failure.The cooling system of the third reactor at the Fukushima nuclear power plant has stopped circulating water following a powerful 7.3 offshore earthquake.

According to the Nuclear Regulatory Agency the cooling system servicing the Unit 3 spent fuel pool is not able to circulate water to cool the nuclear fuel because of a broken pump. The cooling system servicing the Unit 3 spent fuel pool was not able to circulate water to cool the nuclear fuel because of a broken pump, according to the Nuclear Regulatory Agency.
Although the heat in the pool is slowly rising, the agency said that at such a pace the heat is unlikely to rise to a “dangerous level” in any “foreseeable future.”
Tokyo Electric Power Company (TEPCO) told national broadcaster NHK that the cooling system in the Reactor 3 spent fuel pool stopped working. Japan’s national nuclear agency has confirmed that the temperature rise in the pool is “gradual.” The exact cause of the cooling system stoppage is currently unknown. However, the system might have been “shaken” during the earthquake, according to nuclear agency officials, as reported by NHK. No cooling water leaks or any other “abnormalities” have been reported.
DETAILS TO FOLLOW
The temperature in the pool went up to 29 degrees Celsius. It takes up to seven days for temperatures to rise to 65 degrees Celsius, which is the upper operational limit, Japan’s national nuclear agency said.
At such a pace, the cooling system failure posed no “immediate danger,” although the agency admitted “gradual” rise in temperatures.
