small modular reactors

Idaho National Laboratory (INL) has selected the five commercial teams that will potentially demonstrate advanced applications—including data center integration—at its much-watched Microreactor Application Research Validation and Evaluation (MARVEL) platform, an 85-kWth/20-kWe liquid-metal-cooled test bed currently under construction at the lab. The initial selections, unveiled on Dec. 4, mark the “first potential end users for MARVEL,” […]

The UK has confirmed that Wylfa on the island of Anglesey, North Wales, will host three Rolls-Royce small modular reactors (SMRs) that could deliver first power in the mid-2030s—launching a state-backed, fleet-based nuclear deployment through publicly owned entity Great British Energy–Nuclear (GBE-N). The UK government has framed the SMR project, which is underpinned by more […]

CyrusOne’s Jim Roche details how AI-driven workloads, high-density racks, and liquid cooling are transforming the data center–utility relationship. Only a decade ago, few in the power sector could have predicted that the digital economy’s engine—the data center—would become a central concern for utility planners, grid operators, and energy policymakers. For much of its history, data […]

I’m lucky to learn firsthand about some of the world’s most cutting-edge technologies. I’ve seen artificial intelligence ace an AP biology test, long before AI became an everyday tool. I’ve seen genetically modified mosquitoes that stop malaria in its tracks. I’ve seen geothermal wells that go 15,000 feet below the surface of the earth.   But […]

The most significant week in transatlantic nuclear cooperation since the 1950s atomic partnership unfolded Sept. 14–24, 2025, as a coordinated surge of commercial agreements—totaling over $100 billion—spanned advanced reactor deployments, advanced nuclear fuel supply chains, nuclear waste management, maritime nuclear applications, engineering services, and regulatory harmonization. Formalized under the Atlantic Partnership for Advanced Nuclear Energy […]

Advanced nuclear technology firm Oklo has broken ground on its inaugural 75-MWe sodium-cooled fast reactor at an Idaho National Laboratory (INL) site. The project—one of three awarded to the company under the Department of Energy’s (DOE’s) newly established Reactor Pilot Program—is targeting operations between late 2027 and early 2028, though that timeline is contingent on […]

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 […]

In a new pilot program, the U.S. Department of Energy (DOE) issued an ambitious challenge: bring at least three advanced nuclear test reactors to criticality by July 4, 2026. Announced in June, the program sidesteps traditional Nuclear Regulatory Commission (NRC) licensing, seeking instead to authorize full-scale reactors on private sites through DOE’s internal review process. […]

Small modular reactor (SMR) technology developer NuScale Power has unveiled research programs that could advance an energy system that integrates its nuclear technology to produce desalinated water and hydrogen, while reusing brine waste as an industrial feedstock. The research, developed in partnership with the U.S. Department of Energy’s (DOE’s) Pacific Northwest National Laboratory (PNNL) and […]

Talen Energy has restructured and significantly expanded its nuclear energy agreement with Amazon Web Services (AWS), finalizing a 17-year, $18 billion power purchase agreement (PPA) that will supply up to 1,920 MW of carbon-free electricity from the 2.5-GW Susquehanna nuclear plant to Amazon’s data centers across Pennsylvania. The deal, announced on June 11, restructures a […]
