This is follow-up information on operation of a leakage detector for a seawater pipe trench purification system on the sea-side of Unit 3 turbine building.
As a result of a sampling, the water was below the detection limit value. Therefore, we determined that the water found in the detection box was rainwater.
*Cesium-134: Below the detection limit value (the detection limit value: 430Bq/L)
Cesium-137: Below the detection limit value (the detection limit value: 650Bq/L)
We will restart that purification system, after we reconsider the protection against rainwater.
