Penn State and Westinghouse make eVinci microreactor plan official
Penn State and Westinghouse Electric Company are working together to site a new research reactor on Penn State’s University Park, Pa., campus: Westinghouse’s eVinci, a HALEU TRISO-fueled sodium heat-pipe reactor. Penn State has announced that it submitted a letter of intent to host and operate an eVinci reactor to the Nuclear Regulatory Commission on February 28 and plans to engage with the NRC on specific siting decisions. Penn State already boasts the Breazeale reactor, which began operating in 1955 as the first licensed research reactor at a university in the United States. At 70, the Breazeale reactor is still in operation.

A study group comprising personnel from seventeen industrial organizations and working at Brookhaven National Laboratory has evaluated the Liquid Metal Fuel Reactor (LMFR) concept, and has prepared a preliminary design of a large central station power plant feasible for construction in the near future. This paper presents the important characteristics of that design, together with discussions of the economics and of the remaining research and development work required. The plant utilizes a 550 Mw reactor with a circulating fuel solution of U233 dissolved in bismuth and a breeder fluid of thorium bismuthide dispersed in bismuth. Two-thousand (2000) psig, 975°F steam is delivered to a turbo-generator plant, producing 226,000 kw of net electrical power. Power costs, based on both single plants and multiple units utilizing common chemical processing facilities, range from 6.5 to 8.5 mils/kw-hr.
