Highly radioactive water was found at 4 more locations

Tepco found highly contaminated water stocked at additional 4 locations in the trench facilities.

1.

In the pit of water circulating pomp at reactor.

500 m3

Cs-134 : 7.1*10^3 Bq/cm3

Cs-137 : 9.1*10^3 Bq/cm3

 

2.

In the pit of water circulating pomp at reactor3

600 m3

Cs-134 : 3.8*10^2 Bq/cm3

Cs-137 : 4.8*10^2 Bq/cm3

 

3.

In the pit of water circulating pomp at reactor4

Unknown m3

Cs-134 : 9.1*10^0 Bq/cm3

Cs-137 : 1.2*10^1 Bq/cm3

 

4.

The duct of Central radioactive disposal stock facility

Unknown m3

Cs-134 : 7.3*10^-1 Bq/cm3

Cs-137 : 9.4*10^-1 Bq/cm3

 

About 1 and 3, the reason was not announced.

About 2, Tepco assumes it may be from other leaking place of highly radioactive water.

About 4, Tepco assumes it’s from water underground or rain water leaking in.

They are planning to carry the water away.
