The Chemistry and Metallurgy Research Replacement Facility, usually referred to as the CMRR, is a facility under construction at Los Alamos National Laboratory in New Mexico which is part of the United States' nuclear stockpile stewardship program. The facility will replace the aging Chemistry and Metallurgy Research (CMR) facility. It is located in Technical Area 55 (TA-55) and consists of two buildings: the Nuclear Facility (CMRR-NF) and the Radiological Laboratory, Utility, and Office Building (RLUOB). The two buildings will be linked by tunnels and will connect to LANL's existing 30-year-old plutonium facility PF-4. The facility is controversial both because of spiraling costs and because critics argue it will allow for expanded production of plutonium 'pits' and therefore could be used to manufacture new nuclear weapons. ==Background== Construction of the Chemistry and Metallurgy Research (CMR) building began in 1949 and was completed in 1952.〔(【引用サイトリンク】url=http://supply.lanl.gov/Procurement/cmrr/overview.shtml ) 〕 The building contained six wings and in 1959 a seventh laboratory wing was added. In 1960, Los Alamos built Wing 9, a addition containing hot cells with remote handling capabilities. In total, the CMR building now contains roughly of laboratories and related facilities. According to Los Alamos officials, "many of the CMR facility systems and structural components are aged, outmoded, eroding, and generally deteriorating." In 1999, the NNSA decided to plan for the "end-of-life" of the CMR building around 2010.〔〔(【引用サイトリンク】url=http://supply.lanl.gov/Procurement/cmrr/schedule.shtml ) 〕 Thereafter planning began for the CMRR facility which would serve as a replacement. There is evidence the need for an upgrade is real, since in 2010 federal safety auditors reported the building was "seismically fragile and poses a continuing risk to workers and the public." Ground was broken on the CMRR project on January 12, 2006. Construction of the CMRR is proceeding in three phases. The first phase is the construction of the Radiological Laboratory Utility Office Building, which is expected to be finished around 2011.〔 It has an estimated cost of $164 million and will house "a radiological laboratory, a training center, two simulation labs, and cleared and uncleared office space for some 350 Lab personnel".〔 The second phase is the Special Equipment Facility (SPF) and the third phase is the Nuclear Facility (NF).〔(【引用サイトリンク】url=http://www.lanl.gov/prr/Operations_Infrastructure/PRR-OPS-0006.pdf )〕 The initial cost of the CMRR project was approved at $745–$975 Million. The total projected cost in 2008 was reported at $2 billion. In 2010, the total cost of the project was still not finalized but was estimated between $4 and $5 Billion.〔 There is a $4 billion placeholder in the Obama administration's Fiscal Year 2011 budget for the CMRR. In 2010, a top lab manager suggested that the final price tag probably will not be known until 2014.〔 The expected completion date is also unknown but it has been reported the project may not be completed until 2022. 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「Chemistry and Metallurgy Research Replacement Facility」の詳細全文を読む スポンサード リンク
