- At around 7:36 PM on February 16, a cooperative company worker found water overflowing from the water intake tank between the temporary tank storing accumulated water installed outside of Units 5-6 and the desalination system (reverse osmosis membrane). The leaked stopped after stopping the water intake pump on the upstream side of the water intake tank. The amount of leaked water is evaluated to be approx. 19.8m3 and the leaked water has been absorbed into the ground. We have judged that the leaked water has not flowed to the outside considering that there is no side ditch, etc. in the surrounding area. The cause of the leakage is currently under investigation. The radioactivity density analysis results of the leaked water are as follows. Cesium 134: 6.8×10-2Bq/cm3 Cesium 137: 1.3×10-1Bq/cm3 Allγ: 2.0×10-1Bq/cm3
