TOKYO (Kyodo) -- Prime Minister Naoto Kan is considering setting up a big underground tank in the compound of the radiation-spewing Fukushima Daiichi nuclear plant to prevent contaminated water from spilling into the sea, a fishery official said Wednesday.

"There is bedrock 46 meters underground. The government has found that no tainted water will seep below (the bedrock) and is considering building a tank there," Ikuhiro Hattori, who heads the National Federation of Fisheries Cooperatives Associations, quoted Kan as saying.

Hattori talked to the press after he and other executives of the federation held talks with Kan, during which they lodged a protest against the government for allowing the nuclear plant's operator to release a large amount of radioactive water into the Pacific Ocean in early April.

Hattori told Kan the release of radioactive water without any prior consultation is "hard-to-forgive" and asked him to make sure that fishermen receive enough compensation for losses they incurred in the wake of the crisis at the nuclear plant -- which was triggered by the March 11 earthquake and tsunami.

Kan apologized to the executives and promised that the government will be responsible for upcoming damages with the plant's operator, Tokyo Electric Power Co.

The utility unveiled a plan to dump "water containing relatively low levels of radioactive materials" into the sea at the last minute on April 4.

The company known as TEPCO said it was necessary to make space to store more highly radioactive water that has been hindering efforts to bring the plant's overheating reactors under control.

24/04 福島第一原発、高濃度汚染水に専用タンク設置へ

 東京電力は23日、福島第一原子力発電所のタービン建屋や作業用トンネル(トレンチ)などにたまった高濃度の放射性物質に汚染された水について、敷地内の建屋から離れた場所に専用タンクを設置し、移送する方針を明らかにした。

 7月をめどに1万トン分を用意するという。

 東電によると、高濃度汚染水用のタンクには、腐食などを防ぐための特殊な塗装を施す。ただし、放射線を完全に遮断できないため、作業中の建屋から離れた場所に置き、放射線の影響を低減させる。設置には1万平方メートル以上の土地が必要で、敷地内にある「野鳥の森」などの森林を伐採し、場所を確保したいとしている。

 これら高濃度汚染水は、仏企業などの技術を使って新設される浄化装置で最終的に処理される。
