Advanced energy technology group AMPERA announced the company has completed production of what it called the first full-scale, 3D-printed nuclear reactor module.

Centrus Energy has finalized a $900 million task order with the U.S. Department of Energy (DOE) that clears the way for the company to transition its pioneering high-assay low-enriched uranium (HALEU) cascade in Piketon, Ohio, from a government-funded demonstration to private commercial operation. The Bethesda, Maryland-headquartered firm on July 1 announced that its wholly owned subsidiary American […]

The Nuclear Regulatory Commission (NRC) has proposed what may be its most consequential reactor-licensing overhaul in a generation, a 553-page rulemaking that seeks to rewrite core pieces of the regulatory framework governing how commercial nuclear plants are sited, licensed, built, modified, operated, renewed, fueled, and ultimately decommissioned. Issued July 1, the proposed rule, “Modernizing Reactor […]

Deployable Energy’s Unity demonstration reactor has achieved criticality at Idaho National Laboratory (INL), making it the third Department of Energy (DOE)–authorized advanced reactor to reach the milestone ahead of the July 4 deadline set under President Trump’s May 2025 nuclear executive order.

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

For decades, the most radioactive category of low-level waste in the U.S. has had a disposal plan that exists only on paper: a deep geologic repository that was never built. Late last week, the Nuclear Regulatory Commission (NRC) moved to replace that plan with one that can actually be licensed. The agency proposed a sweeping […]

The Nuclear Regulatory Commission (NRC) has proposed a materials-licensing rule that would revise several regulatory handoffs outside the reactor license, including pilot fuel lines, spent fuel reprocessing, dry storage cask approvals, advanced-fuel storage definitions, construction timing, and reporting requirements for fuel-cycle and materials facilities. The proposed rule, Modernizing Materials Licensing, released June 18, seeks to […]
