The most consequential number in current American energy planning is one that nobody in the room where it gets made believes.

When I walk into the main office of a power plant, it’s always on the main TV screen, along with heat rate, load, and other critical numbers. I’m talking about condenser backpressure. Every power plant manager watches this number (Figure 1), and they should. A PEPSE (Performance Evaluation of Power System Efficiencies) analysis of a […]

Five advanced nuclear companies will build, own, and operate more than 20 commercial nuclear microreactors across five U.S. Army installations under the Janus Program, a milestone-based effort designed to place the first project into useful service by September 2028 and establish repeatable commercial products.

Oklo’s Groves Isotope Test Reactor in Lockhart, Texas, has become the fifth reactor to achieve criticality under the U.S. Department of Energy’s Reactor Pilot Program (RPP), and the first under the program to do so on private land. The low-power test reactor reached criticality at 9:19 p.m. ET Aug. 5, achieving a controlled, self-sustaining nuclear […]

Growth in artificial intelligence (AI) is outpacing the world’s ability to generate enough power to sustain it. As AI adoption accelerates worldwide, it’s colliding with a power system that wasn’t built for its level of demand. Vittorio Pierangeli, senior vice president PowerGen at Rolls-Royce Power Systems (Figure 1), explains why electricity, not chips or algorithms, […]

The U.S. Department of Energy’s (DOE’s) Office of Energy Dominance Financing (EDF) closed a loan of up to $3.26 billion to American Electric Power (AEP) Texas on July 8, the office’s third utility

VSB Group, part of TotalEnergies, in June said it had awarded the engineering, procurement, and construction (EPC) contract for a 20-MW solar project in Loberitz, Germany, to UK-headquartered INTEC Energy Solutions.

Nuclear power is experiencing yet another boom. This time it may genuinely lead to a sharp expansion of the global reactor fleet. Several drivers are at work: decarbonization requirements, growing energy

Demand for electricity—particularly for large-load users like data centers—is increasing, raising the question of how best to meet the new demand.

Government officials in China have given the green light for construction of eight new nuclear reactors, as the country looks to add more electricity to meet growing demand for power.

Advanced nuclear firm Aalo Atomics has formed a strategic partnership with energy-first AI infrastructure company Crusoe to develop a nuclear-powered “AI Factory” data center in a project that will combine Aalo’s advanced reactor development program at Idaho National Laboratory (INL) with Crusoe’s modular AI data center platform. The companies said on July 30 that under […]

The U.S. Nuclear Regulatory Commission (NRC) has approved the License Termination Plan (LTP) for the Oyster Creek Generating Station in New Jersey, a regulatory milestone that clears the final phase of decommissioning and sets the stage for Holtec International to pursue construction of four SMR-300 small modular reactor units at the Lacey Township, New Jersey, […]

A varied group of investors has provided Commonwealth Fusion Systems (CFS) with another $1 billion in equity financing, with the company on July 30 saying the funding supports the group’s continuing work toward operating a commercial fusion energy power plant.

The Department of Energy (DOE) has selected Utah, Tennessee, Oklahoma, Louisiana, and Idaho as initial contenders to host Nuclear Lifecycle Innovation Campuses—voluntary federal–state partnerships designed to co-locate fuel fabrication, enrichment, spent fuel reprocessing, and waste disposition within integrated, full‑cycle nuclear ecosystems. U.S. Secretary of Energy Chris Wright signed non-binding memorandums of understanding (MOUs) with the […]

Last week, Microsoft announced a $60 million, multiyear commitment to the Department of Energy’s (DOE’s) Genesis Mission, the national initiative to embed artificial intelligence (AI) across the country’s 17 national laboratories. The company’s stated goal, echoing DOE’s own framing, is to help “double the productivity and impact of American research and innovation within a decade.” […]

A federal appeals court has upheld the Nuclear Regulatory Commission’s (NRC’s) use of a generic environmental analysis for nuclear plant license renewals, rejecting claims that the agency failed to adequately consider how aging components and climate change could affect the risk of severe reactor accidents.
