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 portion of the neutron flux spectrum responsible for producing radiation damage in the light insulators is identified. A simplified method for describing the radiation damage dosage is devised to permit quantitative comparisons between the radiation damage developed in different reactor facilities. The damage rates in facilities of the following reactors are compared: X-10, CP-3', CP-5, Hanford, BNL-1, and LITR; the relation of the damage rates to various quoted fluxes is indicated. It is shown that the damaging flux has no general relation to the total flux, the thermal flux, the resonance flux, or the epithermal flux; it must be monitored for each experiment.
