The […]

An international nuclear power services company has confirmed it plans to submit an application to build new generation capacity at a long-closed nuclear power plant in Wisconsin.

The Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL), Type One Energy and the University of Tennessee in Knoxville are partnering to establish a world-class facility that will drive American innovation and move fusion energy closer to reality. This high-heat flux (HHF) facility, located at the Tennessee Valley Authority’s (TVA) Bull Run Energy Complex in East Tennessee, will evaluate how materials react under extreme conditions in a fusion device.

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 […]

Deep Isolation Nuclear, an innovator in nuclear waste disposal technology, on January 13 said the company has successfully completed its Project SAVANT (Sequential Advancement of Technology for Deep Borehole Disposal), a two-year research initiative funded by the U.S. Department of Energy Advanced Research Projects Agency–Energy (ARPA-E).

For much of the 20th century, the U.S. set the global standard for civilian nuclear energy. American innovation shaped reactor design, safety culture, and regulatory practice worldwide. Yet today, as nuclear power regains prominence amid concerns over climate, energy security, and industrial competitiveness, America faces a quieter but more consequential challenge: the erosion of its nuclear fuel supply chain.

In-Depth: Meta’s suite of three landmark agreements is poised to provide the financial certainty to extend aging plants, accelerate first-of-a-kind advanced reactor deployments, and relieve PJM’s tightening capacity constraints while establishing the hyperscaler as an anchor customer for a 6.6-GW corporate-backed nuclear fleet. In a stunning move that reinforces Big Tech’s growing role in underwriting […]

Recent breakthroughs at U.S. fusion labs, along with new public-private partnerships, are bringing us closer than ever to realizing fusion energy’s limitless potential. However, the U.S. has a major gap to fill in fusion research and development (R&D), and workforce development.

Nuclear energy company Commonwealth Fusion Systems (CFS) said it would collaborate with chipmaker NVIDIA and energy technology group Siemens to develop a digital twin of its SPARC fusion machine. The companies said their work will apply artificial intelligence (AI) and data and project management tools to accelerate commercial fusion.

A North Carolina-headquartered developer of small modular nuclear power plants announced it has an agreement with the U.S. Dept. of Energy (DOE) for an initiative to build and operate a molten salt reactor.

The U.S. Department of Energy (DOE) has issued its first production-scale task orders under a $2.7-billion uranium enrichment program launched in 2024, awarding $900 million each to Centrus Energy Corp., General Matter, and Orano Federal Services to expand domestic capacity for conventional low-enriched uranium (LEU) and high-assay low-enriched uranium (HALEU) over the next decade. The […]

Vattenfall, Industrikraft Advance SMR Program at Ringhals in High-Stakes Deal. Swedish state utility Vattenfall and industrial consortium Industrikraft i Sverige AB signed an agreement, announced on Nov. 10

In early 2020, the prevailing narrative in the power sector was a continuation story of the developments from the decade before: renewable buildout will keep compounding, thermal capacity will keep retiring (albeit at a slower rate), markets will evolve to compensate for flexible generation products, capital will keep moving earlier in the development value chain […]

Entergy Arkansas, the utility that provides electricity to about 735,000 customers in 63 counties in that state, announced a plan to add about 2.6 GW of new power generation capacity, in part by converting old coal-fired units to burn natural gas.
