The Department of Energy’s Office of Clean Energy Demonstrations issued a final environmental assessment (EA) and finding of no significant impact in February for a cost-shared X-energy project to construct and operate a helium test facility (HTF) in Oak Ridge, Tenn. According to the EA, construction would begin in early 2024 and take X-energy and its contracted partner, Kinectrics, about one year to complete. the facility would then operate for six years, with the possibility of extensions for up to an additional 20 years, to test equipment for a demonstration of X-energy’s high-temperature, gas-cooled reactor technology and also to “serve the reactor community at large as the technology continues to develop and is adopted around the world.”

Ontario Power Generation (OPG) and X-energy will look for opportunities to deploy the Xe-100 high-temperature, gas-cooled reactor at industrial sites in Ontario and identify further potential end users and sites throughout Canada under an agreement announced today.

The U.S. state with more nuclear power plants than any other—Illinois—has no operating university research reactors. A team at the University of Illinois at Urbana-Champaign (UIUC) intends to reverse that situation and construct a high-temperature gas-cooled microreactor. If the team's plans go ahead, the first new U.S. university research reactor deployment in about 30 years could also support commercial advanced reactor deployment.
