【ADDITIONAL INTENTIONAL RELEASE is planned - "purified" highly contaminated water to the Pacific】


【ADDITIONAL INTENTIONAL RELEASE is planned - "purified" highly contaminated water to the Pacific】
 汚染地下水を「浄化」し海へ 東電が計画

It is estimated that 200 tons of highly contaminated ground water is seeping into the Pacific Ocean at Fukushima Daiichi NPP site EVERY DAY. (in addition to 400 tons, which was previously reported?)

TEPCO has been constructing seaside impermeable wall to pump contaminated ground water and remove the radioactive materials.

The construction of "Purification" facility has begun, and they expect to complete it as well as impermeable wall by September this year. But the capacity to store "Purified" water is very limited.

Although they are doing bypass release of ground water which is pumped BEFORE getting into the site, they have not "intentionally" released "purified" highly contaminated ground water to the ocean yet.

TEPCO said that they won't implement the plan without a consent from the local fishermen, but also said "it would be better than letting the radioactive water directly leak to the ocean."

福島第一原発では高濃度の汚染水が地中に漏れ出し、これに汚染された地下水およそ200トンが毎日、海に流れ出しているとみられています。

このため東京電力は、護岸沿いに「遮水壁」と呼ばれる鉄製の壁を作って地下水をせき止め、ポンプでくみ上げて放射性物質を取り除くことにしています。

そのための浄化設備の建設はすでに始まっていて、ことし9月に遮水壁と共に完成する予定ですが、地上で保管するタンクの容量にも限界があり、浄化後の水の処分方法が課題となっていました。

福島第一原発では、汚染される前の地下水をくみ上げて海に放出する「地下水バイパス」は行われていますが、汚染された地下水を浄化して海に放出することはこれまで行われていません。

東京電力は「地元の漁業者の同意なく排水することはない。仮に海に放出したとしても汚染水が直接海に流出している現在の状況が改善される」としています。

While ALPS keeps failing its operation, how they can "purify" the contaminated groundwater?

Reminder: how to read a report like this.

”Purified” = filtered (only some isotopes will be filtered to the extent which is possible with current technology and financial capacity)

”Safe” = below standard or limit which is set by each government or company to maintain their economy
