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 […]

Advanced nuclear firm Aalo Atomics has secured new capital and regulatory backing to complete construction of its 10-MWe Aalo-X reactor at Idaho National Laboratory (INL). The project, recently selected under the Department of Energy’s (DOE’s) new Nuclear Reactor Pilot Program, will demonstrate cold criticality by July 2026 in an unusually aggressive federal milestone for advanced […]

With billions of dollars pouring into the sector from power players like Google and Amazon, the data center industry is having a moment. But this surge in investment and interest has also brought up serious questions—particularly around how we are going to power these massive computing engines. According to the U.S. Department of Energy, data […]

The Tennessee Valley Authority (TVA) has signed a first-of-its-kind power purchase agreement (PPA) with advanced nuclear technology firm Kairos Power to buy power from the company’s planned Hermes 2, a molten salt nuclear reactor in Oak Ridge, Tennessee. The deal makes TVA the first U.S. utility to contract for electricity from a Gen-IV reactor. Under […]

Everybody is now jumping on the pro-nuclear bandwagon. With U.S. electricity demand ramping up due to the rapid build-out of energy-intensive data centers across the country, there is finally broad political and business support for dispatchable 24/7 nuclear power to help meet projected load growth and ensure overall grid reliability. The Trump White House, the […]
