El Segundo, Calif.–based start-up Valar Atomics has taken its Ward 250 test reactor critical at the Utah San Rafael Energy Lab (USREL), becoming the second company in the Department of Energy's Reactor Pilot Program to reach the milestone, and, according to the DOE, the first to do so outside a national laboratory.

The DOE celebrated the achievement in a June 18 announcement, describing it as a "zero-power fueled criticality demonstration." The news follows a similar update for Antares Nuclear's Mark-0 reactor, which the DOE said achieved criticality at Idaho National Laboratory earlier this month.

The dormant Blue Castle nuclear power plant project in Utah has resurfaced, only this time as a proposed small modular reactor facility.

Blue Castle Holdings and Fulcrum Point Holdings—founded by the owner of Hi Tech Solutions, a company behind a separate Utah nuclear project—announced last week a joint venture to advance the Blue Castle project in Green River, Utah, the origins of which trace back almost 20 years.

Today is the Department of Energy’s deadline for states to respond to a request for information on proposed Nuclear Lifecycle Innovation Campuses. Issued on January 28, the RFI marks the first step toward potentially establishing voluntary federal-state partnerships designed to build a coherent, end-to-end nuclear fuel cycle strategy for the country, including waste management, according to the DOE.

The past few years have seen a concerted effort from many U.S. states to encourage nuclear development. The momentum behind nuclear-friendly policies has grown considerably, with many states repealing moratoriums, courting nuclear developers and suppliers, and in some cases creating advisory groups and road maps to push deployment of new nuclear reactors.

Utah-based Creekstone Energy has signed a memorandum of understanding (MOU) with EnergySolutions to study the feasibility of building at least 2 gigawatts of advanced nuclear capacity to power a 25-acre data center Creekstone is planning in Delta, Utah.

The Nuclear Regulatory Commission recently announced that it has completed its final safety evaluation (SE) for the construction permit application for Kemmerer Power Station Unit 1 in Kemmerer, Wyo. The application was submitted by TerraPower on behalf of its wholly owned subsidiary, US SFR Owner (USO).

Utah Gov. Spencer Cox joined Brigham City Mayor D. J. Bott this week to announce a new partnership among the state, city, Hi Tech Solutions, and Holtec International. The partnership plans to develop a “full-scale nuclear energy ecosystem” based in Brigham City that will feature advanced manufacturing, workforce development, and Holtec’s SMR-300.

British Columbia, Canada–based Anfield Energy has scheduled a ground-breaking ceremony on November 6 at its Velvet Wood uranium and vanadium mine, located in southeastern Utah’s Lisbon Valley. According to Anfield CEO Corey Dias, it will be “more than a ground breaking—it’s a bold declaration of Anfield’s readiness to help fuel the American nuclear renaissance.”

Almost every day this week has featured headlines concerning announcements, signings, and progress across Utah’s nuclear sector.

At a glance: TerraPower, Flagship, and the state signed a memorandum of understanding to cooperate on siting a Natrium reactor; $5 million may come to Camp Williams for General Matter–related site preparation work; and Nusano cut the ribbon on a radioisotope production facility.

Utah-based waste management company EnergySolutions announced that it has signed a memorandum of understating with the Intermountain Power Agency and the state of Utah to explore the development of advanced nuclear power generation at the Intermountain Power Project (IPP) site near Delta, Utah.

Denver-based Energy Fuels Inc., one of the largest uranium producers in the United States, has signed a landmark agreement with the Navajo Nation on the transport of uranium ore along federal and state highways that cross through Navajo land. The agreement allows the resumption of uranium ore transport from Energy Fuels’ Pinyon Plain Mine in northern Arizona to the company’s White Mesa Mill in southern Utah, where the ore is processed into natural uranium concentrates (U₃O₈).

From lifting moratoriums to launching studies to labeling it as clean, state lawmakers are exploring ways to give nuclear energy a boost in 2025. Here’s a look at some of the pronuclear legislation under review.

Advanced nuclear reactor company Last Energy joined with two Republican state attorneys general in a lawsuit against the Nuclear Regulatory Commission, arguing that some microreactors should not require the commission’s approval.

Energy Fuels has paused transport of uranium ore from its mine south of the Grand Canyon in Arizona to a processing facility in Utah—a path that crosses Navajo Nation land.

In 1953, the United States detonated above­ground nuclear weapons during tests at the Nevada Test Site. In 2011, the Fukushima Daiichi meltdown occurred in Japan. Both events spread radioactive material over many miles and over population centers. Neither event resulted in any adverse health effects from that radiation.

But the response to the Fukushima event was disastrous because of the irrational and misinformed fear of radiation. That fear—not radiation—killed at least 1,600 people and destroyed the lives of at least another 200,000. That fear seriously harmed the entire economy of Japan, stopped cold the fishing industry and other agriculture in that area, and, overnight, reversed the country’s progress in addressing climate change.

The U.S. tests spread two to three times more radiation than did the events of Fukushima over the people of Utah, particularly the town of St. George. Like with Fukushima, no one was hurt, there was never any increase in cancer rates, and no one died as a result. But in Utah, the economy and people’s lives were unaffected. Why was there such a different result?
