EDF will extend the lifetimes of two UK nuclear power plants—Heysham 1 in Lancashire and Hartlepool in Teesside—by an additional 12 months to March 2028 in a bid to secure the country’s energy security as it faces a looming nuclear capacity cliff and heightened reliance on imported gas. The French-owned utility confirmed that 1.2-GW Heysham 1 in […]

The Tennessee Valley Authority (TVA) will collaborate with ENTRA1 Energy—NuScale’s exclusive global strategic partner—to develop a 6-GW nuclear portfolio, including six ENTRA1 Energy power plants on TVA sites, the companies announced on Sept. 2. Under the agreement, ENTRA1 Energy will develop and own nuclear assets across TVA’s seven-state service region, selling electricity to the nation’s […]

Over nearly five decades, nuclear waste has been treated as an intractable problem, locked in dry casks, relegated to repositories that are slow to materialize, and generally viewed as a costly liability

Steam turbine technology is not stagnant. Advanced designs are incorporating innovations in blade design, advanced materials, precision manufacturing, and high-energy steam cycles, delivering significant

Thermal power plants, nuclear and fossil-fueled, rely on cooling water intake structures (CWIS) to withdraw water for rejecting waste heat. The CWIS serves as a critical interface between engineered systems and the natural environment, making it vulnerable to various external factors such as biological growth, water chemistry changes, hydraulic forces, drifting debris, and meteorologic events. […]

Constellation Energy is evaluating specific regulatory pathways to enable potential deployment of advanced nuclear reactors at its Clinton Clean Energy Center. The measure could mark the first concrete steps toward next-generation nuclear development at the Illinois site now that the competitive generator has finalized a landmark 20-year agreement with Meta. Constellation disclosed on Tuesday that […]

The U.S. Department of Energy (DOE) has unveiled three more companies to which it will allocate high-assay low-enriched uranium (HALEU) under conditional commitments in a bid to support advanced reactor development and domestic fuel production. The Aug. 26 announcement marks the second round of allocations under DOE’s HALEU Availability Program but it links to two […]

Holtec International said the Palisades Power Plant, which was closed in 2022 and set for decommissioning, is now the first U.S. nuclear power plant to officially return to operations status. Holtec, which bought the Michigan-based plant to decommission it but instead decided the facility could be restarted, on August 25 said Palisades is now authorized […]

Swedish utility Vattenfall has narrowed its small modular reactor (SMR) supplier selection to two finalists—GE Vernova Hitachi Nuclear Energy’s (GVH’s) BWRX-300 and the Rolls-Royce SMR—for potential construction of new nuclear capacity adjacent to its Ringhals plant site on Sweden’s Värö Peninsula. The announcement represents a critical step in what could become Sweden’s first new nuclear build project in more than 40 years. While the utility ultimately intends […]

Despite nuclear power’s unmatched ability to produce reliable, carbon-free energy at scale, it is often dismissed by clean energy advocates in favor of renewable resources like wind and solar. Cost arguments and public misconceptions around safety and radioactive waste have kept it out of many mainstream climate strategies. But as Tim Gregory argues in his […]
