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.

The adsorption of simulated fission products on slurries of ThO2-UO3 mixtures has been studied. Experiments were performed using tracer techniques employing slurries which had been previously pumped in order that the condition of the slurry as well as concentration of the fission products, temperature, and pressure might simulate reactor conditions. Results of some preliminary experiments designed to remove fission products by the use of eluting agents are also reported.
