Fedorchak

North Dakota’s sole member of the U.S. House of Representatives, Republican freshman Congresswoman Julie Fedorchak, has introduced the Baseload Reliability Protection Act.

The bill aims to “amend the Federal Power Act to prohibit retirements of baseload electric generating units in any area that is served by a Regional Transmission Organization or an Independent System Operator and that the North American Electric Reliability Corporation [NERC] categorizes as at elevated risk or high risk of electricity supply shortfalls, and for other purposes.”

A summary of the legislation is available on Fedorchak’s House website.

Amendments: The Baseload Reliability Protection Act would amend the Federal Power Act in the following ways:

DOE opens Milestone fusion pilot plant program to new companies and teams

June 12, 2025, 12:00PMNuclear News

Eight companies were chosen to develop fusion pilot plant designs through the Department of Energy’s Milestone-Based Fusion Development Program just over two years ago. It wasn’t until June 2024 that the DOE announced that protracted negotiations over program metrics had been concluded. Now, two years on, the original eight are “making great progress,” according to Colleen Nehl, program manager for public-private partnerships in the DOE’s Office of Fusion Energy Sciences (FES). Nehl spoke during a June 4 webinar convened on short notice to discuss the latest fusion Milestone news: a fast-tracked opportunity for additional teams to access remaining Fiscal Year 2025 funding for the Milestone program.

Rolls-Royce SMR has emerged as the United Kingdom’s preferred bidder to build the country’s first small modular reactors following a two-year competition, the U.K. government announced June 10. Rolls-Royce SMR expects to build three SMRs with Great British Energy–Nuclear, subject to contracting later this year and regulatory approvals. Great British Energy–Nuclear will “aim to allocate a site later this year and connect projects to the grid in the mid-2030s.”

ANS, nuclear experts study Trump’s executive orders to overhaul industry

June 9, 2025, 12:02PMNuclear News

In the weeks since President Donald Trump issued four nuclear energy–-focused executive orders (EOs), stakeholders across the nuclear industry weighed in on the plans and details. The American Nuclear Society convened an expert advisory group to study the directives and provide constructive input for the pending implementation.

Former NRC commissioners lend support to efforts to eliminate mandatory hearings

June 6, 2025, 9:29AMNuclear News

A group of nine former commissioners of the Nuclear Regulatory Commission sent a letter Wednesday to the chairs and ranking members of the Senate Environment and Public Works Committee and the House Energy and Commerce Committee, lending their support to efforts to remove mandatory hearings from the reactor licensing process. The move could speed up the new reactor licensing process by about three to six months and save millions of dollars.

Argonne National Laboratory has added a new twist to digital twin technology for research into nuclear energy. According to Rui Hu, a principal nuclear engineer at Argonne, “Our digital twin technology introduces a significant step toward understanding and managing advanced nuclear reactors, enabling us to predict and respond to changes with the required speed and accuracy.”

The research of Hu and his colleagues, “Development of Whole System Digital Twins for Advanced Reactors: Leveraging Graph Neural Networks and SAM Simulations,” was published in the American Nuclear Society journal Nuclear Technology.

Virtual representation: A digital twin technology is an accurate virtual representation of a complex system. It is updated with real-time data from sensors applied to the physical system, such as a nuclear reactor.
