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.

It is shown that the production rate of electron traps during fast neutron bombardment of graphite can be determined by comparing its properties with those of chemically doped graphite. A value of 9 × 10−5 trap per equivalent megawatt day unit of reactor bombardment is obtained. This comparison also shows how the scattering of the carriers is affected by bombardment. The validity of the conclusions which are reached depends upon certain assumptions concerning anisotropy and heterogeneity, which are explored in rather considerable detail.
