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.

Sump-type centrifugal pumps ranging in capacity from 2–1500 gpm have been developed in the Reactor Projects Division, Oak Ridge National Laboratory, for circulating liquid metals and molten salts at temperatures up to 1500°F in metallurgical, heat transfer, and reactor experiments. Each of these pumps uses a nearly conventional bearing assembly to support a vertical shaft and an impeller suspended in a tank containing the high-temperature liquid and an inert blanketing gas. Drive motors and lubrication equipment are external to the pump proper. Seven different models of the sump-type pump have been manufactured and about 400,000 hr of operation has been accumulated in the temperature range 1100–1500°F. Problems resolved in the development of these pumps are discussed. Limitations on the use of this type of pump for reactor and nonreactor applications are noted.
