Fukushima ice wall: TEPCO drills freeze wells to stop contaminated groundwater via RT

The operator of the crippled Fukushima nuclear power plant is erecting an underground wall of frozen soil, which would hopefully stop radioactive water from running into the sea. However, doubts remain over whether it will fix the leak problem.

Tokyo Electric Power Company (TEPCO) pours tons of water into damaged reactors to keep the melted fuel from overheating. But the buildings, which were damaged by the earthquake and tsunami of 2011 and the consequent disaster at the plant, are allowing radioactive material to seep into groundwater and pollute the nearby sea.

In September 2013, the Japanese government announced a plan to drill a row of wells around the area. A liquid coolant running through the wells will cool the soil around them and form a frozen wall in an attempt to prevent contaminated groundwater from getting into the environment.

The work on the wall due to start Wednesday at the Number 2 and Number 3 reactors, Japanese TV station NHK reported.

The program to isolate groundwater is to cost some $320 million in construction plus run costs and is scheduled to be complete by March 2015. The wall, maintained by rows of wells drilled at 1–meter intervals, is to run 500 meters north to south and 200 meters east to west.
