Japan initiates final phase of project to secure Fukushima area
(VOVWORLD) - At Japan’s Fukushima No. 1 nuclear complex, Tokyo Electric Power Company (TEPCO) has initiated the final phase of a post-Fukushima project to extend an underground ice wall to prevent radioactive water from leaking into the sea.
The coolant-filled wall is designed to prevent groundwater from seeping into the facilities and coming into contact with nuclear fuel or mixing with radioactive water inside the reactor building.
Since March last year, the Japanese government has spent 320 million USD to build the “ice wall”. The ice wall is 1.5 kilometers long and sits 30 meters underground, surrounding 4 nuclear reactors on the northeast coast of Japan.
