The Torrance, California–based developer announced on Oct. 27 […]

The Nuclear Company (TNC) has unveiled plans to develop a 6.6-GW nuclear power campus in Lewis County, Kentucky, that could accommodate up to six Westinghouse AP1000 reactors along the Ohio River. The venture-backed developer said it has secured control of a proposed site and intends to pursue federal approvals to begin construction in 2028. The […]

American Electric Power (AEP) and X-energy have agreed to evaluate a 960-MW small modular reactor (SMR) project in Indiana, backed by Amazon development funding and a proposed long-term power purchase agreement designed to protect existing utility customers from project costs. The 12-reactor project would be the second deployment under Amazon and X-energy’s collaboration to develop […]

This year’s Data Center POWER eXchange (DPX), whose programming POWER’s editors curated, was structured to look beyond the scale of opportunity presented by large-load forecasts and delve into the questions they raise. A key focus: What will it take to deliver power infrastructure and data centers on timelines, terms, and operating conditions that both industries […]

Small modular reactors (SMRs) borrow steam turbine engineering from both coal-fired and nuclear plants, but the resulting “wet steam” problem, with exhaust moisture topping 15%, demands a fresh set of

Nuclear plants have accumulated decades of operating experience, technical research, regulatory guidance, and other industry knowledge. Finding the right information, however, can mean searching several separate systems and then piecing the relevant material together. To address that search burden, Atomic Canyon, a company developing artificial intelligence tools for the nuclear industry, built the Nuclear Industry […]

Saeul 3 is the latest evolution of South Korea’s APR1400 program, completed after an extraordinary interruption in national nuclear policy, fortified during construction to address newer safety requirements

Three companies at the forefront of nuclear energy technology have signed a memorandum of understanding (MOU) to evaluate fuel technologies to support advancement of next-generation nuclear 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 […]

At a recent energy conference, power sector stakeholders agreed the looming fleet of hyperscale data centers will require vast amounts of clean, firm capacity. But while nuclear looks like the most plausible

For much of the past decade, the climate and energy debate has been fixated on how electricity is generated: which technologies are cheapest on paper, how renewables can scale fastest, which breakthrough is

Valar Atomics has achieved self-sustaining criticality and completed zero-power testing at Ward 250, its Gen IV tri-structural isotropic (TRISO)-fueled modular high-temperature gas reactor (HTGR), at the Utah San Rafael Energy Lab in Emery County. The project is the second advanced reactor to go critical under the Department of Energy’s (DOE’s) Reactor Pilot Program and the first DOE-authorized […]

Sweden’s nuclear reversal marked three major developments this past week, as advanced modular reactor developer Blykalla and long-established nuclear services firm Studsvik filed separate applications for up to 1.7 GW of new reactors at two sites, while the government formalized an unprecedented financial commitment to another flagship project. The filings, among the first in Sweden’s […]

Duke Energy’s 11-unit nuclear fleet finished 2025 with a capacity factor greater than 97%—its best result on record. For Steven Capps, Duke’s senior vice president and Chief Nuclear Officer, that number is the foundation everything else has to sit on. “2025 was the best year we have had in terms of overall capacity factor for […]

After the encouraging developments from last year and the news from fusion startups receiving funding, a familiar pattern is emerging across energy policy discussions in emerging and developing economies

The U.S. Nuclear Regulatory Commission (NRC) has proposed a sweeping new licensing framework designed to push microreactors out of the lab and onto the grid at unprecedented speed. The proposed rule, called Part 57, is paired with a broader agency overhaul that earlier this year created the Office of Advanced Reactors (OAR), headed by longtime […]

For more than a decade, EPRI has been collaborating across the global supply chain to mature a technology that has the potential to fundamentally change how large nuclear components are manufactured. With the release of EPRI’s Quick Insights: Electron Beam Welding for Heavy Section Components, we now have a clear picture of how far electron […]

A Florida-based startup intends to build factory-produced nuclear systems designed to fit in shipping containers and run for 30 years without refueling. Here’s how the technology works—and where it stands. The global appetite for electricity is surging. Data centers, industrial electrification, and perhaps a coming wave of humanoid robotics are layering exponential demand onto a […]

Across the U.S., more than 60 advanced reactor developers are innovating with billions of dollars in public and private capital to meet rapidly growing electricity demand. But innovation alone does not deliver power. If nuclear power is to be an essential source for exploding power demands across the nation, we must make a strategic choice: […]

On the 40th anniversary of the Chernobyl disaster, POWER sent a freelance photographer and correspondent to the site in Ukraine to document the massive decommissioning effort still underway—and the new

Rolls-Royce SMR and Yokogawa Electric Corp. have announced a strategic agreement for the Japanese industrial automation specialist to deliver data processing and control systems (DPCS) for Rolls-Royce’s small modular reactor (SMR) program—a deal covering the first units in what both companies envision as a global SMR fleet. Under the agreement, Yokogawa will design, engineer, validate, […]

The electricity sector faces a timing problem that’s becoming impossible to ignore. Data centers, artificial intelligence (AI) deployment, industrial reshoring, and broader electrification are driving load growth at rates not seen in decades—and much of that new demand wants carbon-free, firm power. Nuclear checks those boxes. But can the industry deliver capacity fast enough? POWER […]
