At Idaho National Laboratory, researchers have built a bridge between computer models and the lab’s Microreactor Applications Research Validation and Evaluation (MARVEL) microreactor.

Tony Crawford, an INL researcher and MARVEL’s reactivity control system lead, designed a phone booth–sized surrogate nuclear reactor called ViBRANT, or Visual Benign Reactor as Analog for Nuclear Testing, which uses light instead of neutrons to show a “nuclear” reaction.

The Nuclear Regulatory Commission has granted X-energy subsidiary TRISO-X a special nuclear material license for high-assay low-enriched uranium fuel fabrication. The license applies to TRISO-X’s first two planned commercial facilities, known as TX-1 and TX-2, for an initial 40-year period. The facilities are set to be the first new nuclear fuel fabrication plants licensed by the NRC in more than 50 years.

Ontario Power Generation has signed a partnership agreement with the city of Port Hope focused on bringing “large-scale new nuclear generation” to the utility’s Wesleyville location, a 1,300-acre site on the shores of Lake Ontario that has been left undeveloped for four decades. The Ontario government believes that this site has the potential to generate as much as 10 GW of electricity and become “the world’s largest nuclear station,” in the words of Stephen Lecce, the province’s minister of energy and mines.

The Department of Energy’s Office of Environmental Management said crews at the Hanford Site near Richland, Wash., have started retrieving radioactive waste from Tank A-106, a 1-million-gallon underground storage tank built in the 1950s.

Tank A-106 will be the 24th single-shell tank that crews have cleaned out at Hanford, which is home to 177 underground waste storage tanks: 149 single-shell tanks and 28 double-shell tanks. Ranging from 55,000 gallons to more than 1 million gallons in capacity, the tanks hold around 56 million gallons of chemical and radioactive waste resulting from plutonium production at the site.

Gallego and Risch submit ARC Act 2.0 in the Senate

February 11, 2026, 1:33PMNuclear News

Sens. Jim Risch (R., Idaho) and Ruben Gallego (D., Ariz.) reintroduced the Accelerating Reliable Capacity (ARC) Act in the Senate on February 10.

According to the Department of Energy, it could take up to 10 deployments for a reactor design to become a mature commercial reactor. Getting from the first-of-a-kind (FOAK) to full commercial deployment is challenging, and the risks of higher costs and longer deployment timelines for early nuclear projects create significant uncertainty for investors. The ARC Act is designed to reduce that early deployment risk.
