Washington Nuclear Project Nos. 1 and 4, abbreviated as WNP-1 and WNP-4 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.[2]
WNP-1 and -4 are located on 972 acres (393 ha), within the boundaries of the Hanford Reservation in the U.S. state of Washington, approximately 1.5 miles (2.4 km) east of the Columbia Generating Station. The WNP-1 site has been selected as a location for small modular reactors: Washington Xe-100 reactor site.[3][4]
