Researchers at the Department of Energy’s Oak Ridge National Laboratory want to make the sensors in nuclear power plants more accurate by linking them to electronics that can withstand the intense radiation inside a reactor. Electronics containing transistors made with gallium nitride, a wide-bandgap semiconductor, have been tested in the ionizing radiation environment of space. Now, according to a June 24 article from ORNL, tests carried out in the research reactor at Ohio State University indicate they could withstand neutron bombardment within a nuclear fission reactor.

Pearle Lipinski is a nuclear engineering Ph.D. student in Ohio State University’s Department of Mechanical and Aerospace Engineering (MAE). In October 2022, at the International Atomic Energy Agency’s fifth International Ministerial Conference on Nuclear Power in the 21st Century (also known as the Nuclear Power Ministerial, or NPM), she acted as a student social media ambassador, where she was a “huge success in getting the word out,” according to Lei Raymond Cao, director of the OSU nuclear engineering program.

A bipartisan group of legislators has introduced a bill to invest in university nuclear science and engineering infrastructure, establish regional consortia to promote collaboration with industry and national laboratories, and support the development of advanced reactor technology. The National Nuclear University Research Infrastructure Reinvestment Act of 2021 (H.R. 4819) was introduced in the House of Representatives by Reps. Anthony Gonzalez (R., Ohio), Sean Casten (D., Ill.), Peter Meijer (R., Mich.), and Bill Foster (D., Ill).
