Washington Nuclear Project Nos. 3 and 5, abbreviated as WNP-3 and WNP-5 (collectively known as the Satsop Nuclear Power Plant) were two of the five nuclear power plants on which construction was started by the Washington Public Power Supply System (WPPSS) in order to meet projected electricity demand in the Pacific Northwest. WNP-1, WNP-2 and WNP-3 were part of the original 1968 plan, with WNP-4 (a twin to WNP-1 and located at the same site) and WNP-5 (a twin to WNP-3, in similar fashion) added in the early 1970s. WNP-3 and WNP-5 are located on on the Satsop Site near Elma in Grays Harbor County, Washington (N46° 57.536' W123° 28.163'). Today the site hosts the (Satsop Development Park ) and the Grays Harbor Energy Center. ==History== WPPSS applied for a construction and operation permit in 1973, and both WNP-3 and WNP-5 started construction in 1977. Major management changes at WPPSS resulting from cost overruns led to the appointment of Bechtel as the construction manager for all five WPPSS nuclear plants in 1980.〔 WNP-3 was WPPSS's "showcase" project and construction advanced at an estimated rate of 2% per month starting from the appointment of Bechtel, but just a few years later, with the failure of WPPSS to sell nearly in bonds to complete the project, WNP-3 was placed in an extended construction delay in July 1983 while nearly 76 percent complete.〔 Construction on WNP-5 was terminated in January 1982 while only 16 percent complete.〔 Of the original five proposed nuclear units, only WNP-2 was completed and put into operation. Equipment at WNP-3 was preserved to allow a restart of construction if regional energy demand warranted it. In 1994, the WPPSS board adopted a resolution to terminate WNP-3, and preservation funding was discontinued in 1995.〔 Construction Permit CPPR-154 was terminated in 1999 and the ownership of the site was transferred to the Satsop Redevelopment Project. Under contemporary plans, none of the existing structures were slated for demolition, although some equipment (such as the WNP-3 turbine) was to be removed and existing buildings were to be reconfigured to support the conversion of the site to an industrial, business or research park.〔 Approximately of the site were retained by WPPSS for development of a combustion turbine electric generating plant, which later came to fruition as the combined-cycle Grays Harbor Energy Center. Grays Harbor provides 650 MW of electric generation and came on-line in 2008, with an additional 650 MW of generation approved but not yet constructed. 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「WNP-3 and WNP-5」の詳細全文を読む スポンサード リンク
