Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.

TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Oak Ridge National Laboratory has successfully removed legacy radioactive waste stored for more than five decades, marking a significant cleanup milestone. The Oak Ridge Office of Environmental Management (OREM) and cleanup contractor UCOR processed and shipped highly radioactive source material, including radium-226 and boron, out of state for permanent disposal.

A group of universities led by the American Association of Universities (AAU) acted swiftly to oppose a policy action by the Department of Energy that would cut the funds it pays to universities for the indirect costs of research under DOE grants. The group filed suit Monday, April 14, challenging a what it termed a “flagrantly unlawful action” that could “devastate scientific research at America’s universities.”

By Wednesday, the U.S. District Court judge hearing the case issued a temporary restraining order effective nationwide, preventing the DOE from implementing the policy or terminating any existing grants.

Leaders in Ghana announced recently that the country has a “framework agreement” with U.S.-based companies NuScale and Regnum Technology Group.

The announcement made by Stephen Yamoah, executive director of Nuclear Power Ghana, was reported by the Ghana News Agency on March 31. He also said Japanese firms will be working in partnership with NuScale and Regnum on the small modular reactors while the China National Nuclear Corporation will construct a large reactor.

The University of Missouri announced today that it has signed a $10 million contract for the initial design phase of the $1 billion-plus state-of-the-art NextGen MURR research reactor project.

The Federal Energy Regulatory Commission has doubled down on its rejection of an interconnection service agreement (ISA) between Amazon Web Services and Talen Energy in Pennsylvania.

Inertial fusion energy (IFE) developer Pacific Fusion, based in Fremont, Calif., announced this morning that it is on target to achieve net facility gain—more fusion energy out than all energy stored in the system—with a demonstration system by 2030, and backs the claim with a technical paper published yesterday on arXiv: “Affordable, manageable, practical, and scalable (AMPS) high-yield and high-gain inertial fusion.”

Plans to bring a university research reactor like no other to the campus of the University of Illinois at Urbana-Champaign (UIUC) were punctuated last fall by the news that Ultra Safe Nuclear, the developer of the gas-cooled reactor technology selected for the Illinois Microreactor Project, had declared bankruptcy.

Researchers at GE Hitachi Nuclear recently completed a successful test on potential new building blocks made of steel-concrete composite.

The Defense Innovation Unit announced April 10 next steps in the Advanced Nuclear Power for Installations (ANPI) program, launched in 2024 to deploy microreactor nuclear systems for increased power reliability at select military locations.
