X-energy has opened a regional operations and training center aimed at supporting future deployment of its advanced modular nuclear reactor fleet and the operators who will run it.

In March 1949—75 years ago this month—the 25-kilowatt reactor known as Clementine reached full power. As an experimental reactor, it had a rather long and successful run. It was the world’s first fast neutron (high-energy) reactor and operated from initial criticality in 1946 to final shutdown in 1952.

Staff and researchers at Penn State’s Radiation Science and Engineering Center (RSEC) will work this year to install a small angle neutron scattering (SANS) device and become the first and only U.S. university research reactor to host SANS capability. The $9.8 million device, donated by Helmholtz Zentrum Berlin (HZB) in Germany, will help researchers determine the structure of organic materials such as polymers, complex fluids, and biomolecules.

The owners of the Diablo Canyon nuclear power plant plan to dredge a massive buildup of shoaled sediment from its seawater intake cove.
Pacific Gas and Electric spokesperson Suzanne Hosn said, “The dredging project in the Diablo Canyon marina will remove approximately 70,000 cubic yards of sediment to prevent circumstances that could impact the power plant’s cooling system. Dredging will take place for the first time since operations began because of a rapid increase in sediment.”

Lightbridge Corporation announced today that it has reached “a critical milestone” in the development of its extruded solid fuel technology. Coupon samples using an alloy of zirconium and depleted uranium—not the high-assay low-enriched uranium (HALEU) that Lightbridge plans to use to manufacture its fuel for the commercial market—were extruded at Idaho National Laboratory’s Materials and Fuels Complex.

China is on pace to add as many as 10 reactors a year and may surpass the United States’ total nuclear capacity by 2030.
As part of this growth, construction is wrapping up this month on the world’s first onshore commercial modular pressurized water reactor—Linglong One, which is located in the Hainan province. That’s according to China Metallurgical News, an established news unit reporting on China’s industrial chain.
Hitachi pulled out of plans for a nuclear project at Wylfa in 2020 (Image: Horizon Nuclear Power)
Great Britain announced last week that it will purchase land at two nuclear sites from Hitachi for £160 million ($203 million).
Chancellor Jeremy Hunt announced the deal for the sites—Wylfa in northern Wales and Oldbury-on-Severn in southwestern England—during the annual budget speech to Parliament. Under Hitachi’s ownership, the land was prepped for developing a pair of advanced boiling water reactor units, but those plans were suspended in 2019 due to economic constraints.

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.”

Three climate groups filed a motion for the immediate closure of Diablo Canyon nuclear power plant in California, saying the nuclear plant poses an “unacceptable safety risk.”
