This is a follow-up report on the investigation statuses of the water leakage found at the desalination system 3 (reverse osmosis membrane RO-3).
The nuclide analysis results of leaked water are as follows.
Cs-134: 5.7×10-1 [Bq/cm3]
Cs-137: 1.7×100 [Bq/cm3]
Co-60: 1.4×10-1 [Bq/cm3]
Sb-125: 1.5×101 [Bq/cm3]
All β: 2.6×104 [Bq/cm3]
According to the above results, we judged that the leaked water was the water before treatment at the entrance of the desalination system 3 (reverse osmosis membrane RO-3).
We will continue to identify the cause of the leakage.
