On 6/2/2016, Tepco reported to NRA (Nuclear Regulation Authority) that they need to inject cement to “frozen” water wall and NRA admitted it.

The feasibility of frozen water wall project was questioned since before the beginning. In the meeting of NRA, Tepco admitted the temperature remains nearly 10 ℃ at 4 “freezing” points to cause no improvement to stop contaminated groundwater. It has been in freezing operation for over 2 months.

These 4 points are situated between the reactor buildings and the sea. The volume of contaminated water to be pumped up has not been decreased regardless of the frozen water wall.

Tepco states the temperature remains over 0 ℃ because of the high speed of groundwater. They inject cement to slower the water.
