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, the residual heat removal B system and cooling of the reactor was restarted. After that, emergency gas treatment system A was suspended at 12:32 PM and emergency gas treatment system B was suspended at 12:34 PM, since air conditioning of the Reactor Building was restarted at 12:22 PM. No abnormality was found in the operation status after the restart of the air conditioning.
The water temperature of the reactor as of 13:00 PM is 28.0℃, which is stable.
We will continue to investigate the cause of the suspension of the residual heat removal B system.
