Steel wall being built to prevent radiation in Pacific

Steel wall being built to prevent radiation in Pacific

The engineers plan to build 120 metre wide wall of steel sheets to form a 'silt curtain' for the radioactive material, as the reactor makers Toshiba submitted drafts to the government to decommission the four stricken units in around 10 years time, Kyodo news agency reported, quoting Japanese officials.

After struggling for weeks to contain radioactivity at the crippled plant, the engineers apparently have decided to go for decommissioning of the affected units.
Kyodo said, the time frame submitted by the reactor makers was around two thirds of the time taken to dismantle the Three Mile Island nuclear plant in the US after a 1979 incident in which part of a reactor core melted.

With the world's worst nuclear accident since Chernobyl dragging on for months with no end in sight, the government woes were compounded with residents of towns, surrounding the crippled nuclear plants starting to return homes, in defiance of warnings to stay away.

The workers also stepped up efforts to remove highly radioactive water from a tunnel of reactor Nos 2, as they try to cool their cores and plug leaks amid warnings that the crisis is far from over.

Tokyo Electric Power Company says contaminated water in a concrete tunnel of the Number 2 reactor has risen 10 centimeters since leakage of the water into the ocean stopped on Wednesday, the NHK News reported.

Meanwhile, Economy, Trade and Industry Minister Banri Kaieda, meanwhile, met with Fukushima Gov. Yuhei Sato in the city of Fukushima, and plans to visit the crippled Nuclear Power Station later in the day.

The visit, aimed at encouraging those engaged in stabilisation efforts and checking on the plant's damaged reactors, would be the first by a Cabinet minister after the six-reactor plant was rocked by explosions and began spewing radioactive materials in mid-March.

The power supplier stopped the leakage of water contaminated with radioactive materials from near the intake on Wednesday. But facing mounting environmental concerns, it hopes that the installation will help prevent contaminated water from spreading outside the plant's bay.

The radioactive iodine reading was 63,000 times the legal limit in seawater near the intake a day after contaminated water stopped leaking into the sea.
