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.

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.

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 […]

The U.S. Department of Energy released an $83.2 million loan disbursement to Holtec International on Thursday, bringing total federal funding to $335.1 million as the company moves toward completing America’s first commercial nuclear reactor restart. The fifth installment under DOE’s $1.52 billion loan guarantee follows key Nuclear Regulatory Commission (NRC)  approvals that authorized Holtec to […]

The Trump administration has proposed new drone regulations that will eliminate case-by-case approval processes for beyond visual line of sight (BVLOS)  operations, while Acting NASA Administrator Sean Duffy confirmed accelerated plans to deploy a nuclear reactor on the moon by 2030.
