Japan to Begin Underground Ice Wall at Fukushima
June 2, 2014
Japan will on Monday start constructing an underground ice wall at the crippled Fukushima nuclear plant, freezing the soil under broken reactors to slow the build-up of radioactive water, officials said.
The wall is intended to block groundwater from nearby hillsides that has been flowing under the plant and mixing with polluted water already there.
The Nuclear Regulation Authority, the national watchdog, last week gave the go-ahead to beginning the construction of the ice wall at Fukushima Daiichi, owned and operated by Tokyo Electric Power Co (TEPCO).
