翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Plum Brook Reactor ： ウィキペディア英語版 Plum Brook Reactor The Plum Brook Reactor was a NASA 60 megawatt water-cooled and moderated research nuclear reactor,〔Mark D. Bowles and Robert S. Arrighi (August 2004), (NASA's Nuclear Frontier: The Plum Brook Nuclear Facility ), ''NASA Monographs in Aerospace History'' 33.〕〔(SP-4317 ) Science in Flux: NASA’s Nuclear Program at Plum Brook Station 1955 – 2005, Mark D. Bowles, 2006〕 located in Sandusky, Ohio, 50 mi west of the NASA Glenn Research Center (at that time the NASA Lewis Research Center) in Cleveland, of which it was organizationally a part. The reactor was originally planned for the NCAA nuclear airplane project, but after that was cancelled in 1961—by chance just before the initiation of the Apollo Project—it morphed into the primary NASA facility for space-related nuclear energy research and development, including scientific and technical investigations of nuclear energy for spaceflight propulsion, nuclear power systems, and radiation exposure.〔(NASA Plum Brook Reactor Facility ), Great Images in NASA.〕 The station included several large test facilities besides the reactor, including liquid hydrogen facilities for development and testing of the Centaur upper stage. The reactor first went critical on 14 June 1971, and was finally shut down on 5 January 1973. The facility's decommissioning began in 1998, and the last of its structures was demolished in May 2012. The entire process ultimately cost $253 million, significantly more than the inflation-adjusted cost of constructing the facility. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Plum Brook Reactor」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
