[The present condition of the 1st nuclear power plant of Fukushima] (May 20, 2014) A frozen ground wall, uneven pace The government which gets impatient, the prudent regulation committee
Toden and the Nuclear Regulatory Commission are not in step with the government involving the frozen ground impervious wall which is due to be installed in the 1st nuclear power plant of Tokyo Electric Power Fukushima.
As a conclusive factor which stops the increase in contaminated water, the regulation committee thrust one question of an effect, necessity, and a safety aspect after another before to the government which gets impatient for a result.
The formal groundbreaking in June which was being planned is a difficult prospect, and the measure of the Abe Administration good offices is likely to stumble at the beginning.
▽ embarrassment
Was examination of "land subsidence carried out?
It is not asking for the answer "the teacher of the very first rank said like this"."
The investigative commission of the regulation committee in April.
The person in charge of the Agency of Natural Resources and Energy explaining the examination circumstances of the frozen ground wall by an expert, the Ministry of Economy, Trade and Industry, and Fuketa Toyoshi (- and the means which advanced) The committee's words were taken by surprise.
A frozen ground wall is the mechanism of burying the freeze pipe which pours in a coolant to about 30 meters below ground at intervals of 1 meter, and freezing the underground between pipes.
It is scheduled to enclose about 1.5 km of circumferences of No. 1?4, to intercept inflow of groundwater to a building, and to stop that contaminated water increases in number.
Fuketa committee points out the concern which land subsidence produces by the dignity of a building, as a result of stopping a lot of groundwater with a frozen ground wall.
Energy agency Tatsuya Shinkawa perplexed expression was not able to be hidden although the section head responded saying "I would like to arrange indication."
▽ excuse
The contaminated water problem which continues in April, last year and afterwards is one of the "omens" for the Abe Administration which maintains a high approval rating.
The frozen ground wall which supplies national expenditure is an eyeball in which the posture "where a country stands on the front" is shown.
In an actual proof examination, high anti-water is demonstrated and the government expects the drastic measure for a contaminated water problem.
There is also the political side in the circumstances as which the frozen ground system was merely adopted.
"Toden was not interested to the impervious wall which requires money.
(technically) A budget is not attached if not difficult (country)."
It serves as a chairperson in a governmental contaminated water processing task force. Yuzo Onishi The Kansai University specially-appointed professor reveals a situation.
While the Democratic Party Administration age and Toden agree on impervious wall installation of a clay system, the financial aggravation by a large amount of expenses is feared, and there are the circumstances made into wastepaper.
A country gives a budget on the principle of technical development, and the frozen ground wall of the scale "it is [ a scale ] unprecedented at home" (a responsible organization's major construction company, KAJIMA) also has the implications of an excuse to perform Toden.
▽ -- opaque
Economy, Trade and Industry Minister Toshimitsu Motegi -- Toden Naoki Hirose (fathomせ- seeing in addition) having pointed to installation of a frozen ground wall to the president -- May, last year.
As for an argument getting into stride, recognition with future was shown [ which "can carry out examination with three applications" (Fuketa committee) although Toden applied for enforcement to the regulation committee in March, this year ].
It has an experience of the 1st nuclear power plant head. Takuya Hattori (or [ it cooks with a start ]) The Japan Atomic Industrial Forum chairman of the board of directors presents a question to "if the structure which the regulation side also becomes together and considers it is not built from the stage of a concept, it will not be clear anymore what 10 year decommissioning takes", and the state of examination.
On the other hand, the opacity of a decision process is also indicated "It is said that he would like to know from overseas why it was decided that it would be a frozen ground wall."
It is worried about the badness of cooperation of the government, Toden, and the regulation committee.

【福島第1原発の現状】（２０１４年５月２０日） 凍土壁、そろわぬ足並み 焦る政府、慎重な規制委
東京電力福島第１原発で設置予定の凍土遮水壁をめぐり、政府と東電、原子力規制委員会の足並みがそろわない。汚染水の増加を止める決め手として、成果を焦る政府に対し、規制委は効果や必要性、安全面の疑問を次々に突き付けた。予定していた６月の本格着工は困難な見通しで、安倍政権肝いりの施策は出だしでつまずきそうだ。
▽当惑
「地盤沈下の検討はしたのか。『超一流の先生がこう言った』という答えは求めていない」。４月に開かれた規制委の検討会。有識者による凍土壁の検討経緯を説明していた経済産業省資源エネルギー庁の担当者は、 更田豊志 （ふけた・とよし） 委員の言葉に虚を突かれた。
凍土壁は冷却材を流し込む凍結管を１メートル間隔で地下約３０メートルまで埋め、管の間の地中を凍らせる仕組み。１～４号機の周囲約１・５キロを囲い、建屋への地下水の流入を遮断し、汚染水が増えるのを食い止める計画だ。
更田委員は凍土壁で大量の地下水を止めた結果、建屋の重みで地盤沈下が生じる懸念を指摘。エネ庁の 新川達也 （しんかわ・たつや） 室長は「指摘を整理したい」と応じたが、当惑した表情を隠せなかった。
▽口実
昨年４月以降続く汚染水問題は、高い支持率を保つ安倍政権にとって「鬼門」の一つ。国費を投入する凍土壁は「国が前面に立つ」姿勢を示す目玉だ。実証試験では高い遮水性能を発揮しており、政府は汚染水問題の抜本対策と期待する。
ただ凍土方式が採用された経緯には政治的な側面もある。「東電はカネがかかる遮水壁に乗り気でなかった。（技術的に）難しくなければ（国の）予算はつかない」。政府の汚染水処理対策委員会で委員長を務める 大西有三 （おおにし・ゆうぞう） 関西大特任教授は事情を明かす。
民主党政権時代、東電は粘土方式の遮水壁設置に合意しながら、巨額の費用による財務悪化を恐れ、ほごにした経緯がある。「国内に前例がない」（実施主体の大手ゼネコン、鹿島）規模の凍土壁は、技術開発の建前で国が予算をつけ、東電に実行させる口実の意味合いもある。
▽不透明
茂木敏充経産相が東電の 広瀬直己 （ひろせ・なおみ） 社長に凍土壁の設置を指示したのは昨年５月。東電は今年３月に規制委に実施を申請したが「３枚の申請書では審査のしようがない」（更田委員）と、議論が本格化するのはこれからとの認識を示した。
第１原発所長の経験もある 服部拓也 （はっとり・たくや） 日本原子力産業協会理事長は「構想の段階から規制側も一緒になって考える仕組みをつくらないと、廃炉が何十年かかるか分からなくなる」と、審査の在り方に疑問を呈する。一方で、「海外からはどうして凍土壁に決まったのか知りたいと言われる」と、決定過程の不透明さも指摘。政府、東電と規制委の連携の悪さを心配している。
