The N-Reactor was a water/graphite-moderated nuclear reactor constructed during the Cold War and operated by the U.S. government at the Hanford Site in Washington; it began production in 1963. It was a one-of-a-kind design in the U.S., being both a plutonium production reactor for nuclear weapons and, from 1966, producing electricity to feed the civilian power grid via the Washington Public Power Supply System (WPPSS).〔(HANFORD SITE: PROCESSES AND FACILITIES HISTORY, Section 2.2 N Reactor Operations ) Michele Gerber PhD, June 1996〕 In an improvement on the earlier Hanford reactors, N-Reactor was built with a confinement building (although not a containment building). In the event of an accidental release of steam, air and steam would vent through filters that confined any radioactive particles present.〔(US Department of State Bulletin, "Soviet nuclear reactor accident at Chernobyl" )〕 It was partially moderated with graphite, but had a negative void coefficient due to also using moderation from the coolant water, meaning it was thermally stable.〔(Bodansky, ''Nuclear Energy Principles, Practices, and Prospects'', 2004 )〕 The reactor was shut down in 1987 and placed on cold standby in 1988, with "final disposition" beginning in 1994. == See also == *Nuclear power *List of nuclear reactors 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「N-Reactor」の詳細全文を読む スポンサード リンク
