The OK-650 reactor is the nuclear fission reactor used for the singular purpose of powering the Soviet Navy's Project 685 Плавник/''Plavnik'' (Mike), Project 971 Щука-Б/''Shchuka-B'' (Akula),〔(【引用サイトリンク】url=http://www.subsim.com/ssr/akula2.html )〕 and Project 945 Барракуда/''Barrakuda'', Кондор/''Kondor'', and Марс/''Mars'' (Sierra) submarines, and in pairs to power the Project 941 Акула/''Akula'' (Typhoon) and Project 949 Гранит/''Granit'' and Антей/''Antei'' (Oscar) third generation submarines. This pressurized water reactor (PWR) uses 20-45% enriched uranium-235〔(【引用サイトリンク】url=http://fissilematerials.org/blog/2012/03/russia_hands_over_a_nucle.html )〕 fuel to produce 190 MW of power. Developed during the 1970s, these reactors were designed with the aim of minimizing accidents and malfunctions. Monitoring subsystems, designed for rapid detection of leaks, were included, along with newer-generation emergency cooling systems for the main reactor core.〔(【引用サイトリンク】url=http://www.bellona.org/reports/The_Russian_Northern_Fleet_report_chapters/1175895305.68 )〕 The reactor is now also used to power the new Project 955 Borei submarines. It was developed by OKBM Afrikantov. ==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「OK-650 reactor」の詳細全文を読む スポンサード リンク
