This is a follow-up report on the statuses of suspension of the residual heat removal B system after the 6.9 kV metal-clad (power panel) C at Unit 6 was suspended during the logic verifying test (automatic starting test) of Unit 6 emergency diesel generator at Fukushima Daiichi Nuclear Power Station at around 10:16 AM today (July 25).
At 12:06 PM, we have restarted the residual heat removal B system and cooling of the reactor.
No abnormality was found in the operation status after the restart of the system.
The water temperature of the reactor as of 12:00 PM is 27.6℃, which is sufficiently lower than the maximum allowed temperature (100℃). We are currently investigating the cause of the suspension of the residual heat removal B system.
