This is follow-up information and data correction regarding the water leak from the underground reservoir No. 2 in Fukushima Daiichi NPS.
To add one more temporary pump (approx. 30 m3/h), we temporarily stopped the three temporary pumps at 12:07 pm. At 12:52 pm, we started operating the additional temporary pump after we had confirmed the condition of the temporary transferring line.
At 12:55 pm, we conducted an on-site survey and confirmed that there is no abnormality such as leakage on the transferring line.
At 12:57 pm, we started operating the three temporary pump, and we conducted an on-site survey at 12:58 pm and confirmed that there was no abnormality such as leakage on the transferring line.
