decommission 復習
福島第1原発の炉内調査に東芝の新たなつり下げカメラが導入されました。
Toshiba Corp's energy systems unit on Friday unveiled a long telescopic pipe carrying a pan-tilt camera designed to gather crucial information about the situation inside the reactor chambers at Japan's tsunami-wrecked Fukushima nuclear plant.

The Fukushima plant had triple meltdowns following the 2011 quake and tsunami. Finding details about the fuel debris is crucial to determining the right method and technology for its removal at each reactor, the most challenging process to safely carry out the plant's decades-long decommissioning.

decommission/dìːkəmíʃən/を取り上げます。commission が「委任、任務、将校任命辞令」やその動詞の意味を持つので、接頭辞de-がついた意味を推測しやすいと思います。まずLDOCEで定義を確認すると“to stop using a ship, weapon, or nuclear reactor and take it to pieces”とありました。次に『ジーニアス英和辞典』を引くと「〈船・航空機など〉の就役を解く、…を退役させる」とありました。(Kiwi girl)
