X-energy and Centrus Energy announced last week that they have completed the preliminary design of the TRISO-X fuel fabrication facility and have signed a contract for the next phase of work. The planned facility would produce TRISO fuel particles and pack those particles into fuel forms, including the spherical graphite “pebbles” needed to fuel X-energy’s Xe-100 high-temperature gas reactor.

The Department of Energy is considering solidifying 2,000 gallons of Hanford’s tank waste and disposing of it as low-level radioactive waste at an off-site facility. A virtual public meeting on the proposed disposal plan is scheduled for November 18.

As I write this column, it’s late September, and I’m sitting in Dulles Airport waiting for my connecting flight back to Charlotte from Vienna, Austria, where I attended the 65th General Conference of the International Atomic Energy Agency. It was quite an experience, and I want to share a few observations with you. But first, let me provide some background on the IAEA, which is perhaps not as well-­known to Americans as to those in other countries.

The IAEA was established in 1957 within the United Nations family and as an outgrowth of President Dwight Eisenhower’s famous 1953 “Atoms for Peace” speech. It is the world’s central intergovernmental forum for scientific and technical cooperation in the nuclear field. The objectives of the IAEA’s dual mission—to promote and control the use of the atom—are defined in Article II of the IAEA Statute.

“A group of professionals having fun in the fields of decommissioning and environmental sciences for the nuclear industry.”

That’s how the ANS DESD describes itself on its website. The focus of this professional division is the development and use of skills and technologies needed for the optimal management of the end-­of-­life care (decommissioning, decontamination, and remediation), long-­term surveillance, and maintenance of nuclear installations, materials, facilities, and sites.

Idaho National Laboratory recently released footage of a new experiment at its Transient Reactor Test Facility (TREAT) that simulates what happens to a nuclear fuel pin when it starts to overheat. Go to Twitter for the original post, or cut to the chase and watch a 14-second clip on YouTube.

Depending on where you reside on this nuclear technology world of ours, you may care a great deal, or not at all, about who happens to be sitting on the Nuclear Regulatory Commission at any given point in time. If you live on the Department of Energy continent or the Academia continent, it’s probably not a big deal. If you are on the Nuclear Power Plant Operator continent or the Vendor continent (which are actually part of the same landmass), it is quite important. If you are on the NRC island, it’s huge.

The NRC comprises five presidentially appointed, U.S. Senate–confirmed commissioners who are commonly referred to as “the Commission,” and approximately 3,000 federal employees referred to as the staff. The Commission oversees the NRC staff; together, they license and regulate the nation’s civilian use of radioactive materials to provide reasonable assurance of adequate protection of public health and safety. The president of the United States designates one of the commissioners to serve as chairman, the principal executive officer of and the official spokesperson for the agency.

International nuclear safeguards verification relies on a precise count of isotope particles collected on swipes during International Atomic Energy Agency inspections of nuclear facilities and isolated through a series of lengthy chemical separations that can take about 30 days to complete. On October 15, Oak Ridge National Laboratory—a member of the IAEA’s Network of Analytical Laboratories (NWAL)—announced that analytical chemists at the site have developed a faster way to measure isotopic ratios of uranium and plutonium collected on swipes, which could help IAEA analysts detect the presence of undeclared nuclear activities or material.

Here is a recap of industry happenings over the course of the past month:

Ukraine’s Energoatom signs deals for nuclear power exploration and deployment

Energoatom, the state-owned nuclear utility of Ukraine, and Westinghouse Electric Company have signed an agreement to bring Westinghouse AP1000 reactors to multiple sites in Ukraine. The signing took place at the U.S. Department of Energy headquarters in Washington, D.C., and was witnessed by Ukraine’s president Volodymyr Zelensky, U.S. energy secretary Jennifer Granholm, and Ukraine’s energy minister German Galushchenko.

In addition, Energoatom signed a memorandum of understanding with NuScale Power to explore small modular reactor deployment in Ukraine. Under the MOU, NuScale will support Energoatom’s examination of NuScale’s SMR technology, including a feasibility study for proposed project sites and the development of a project timeline and deliverables, cost studies, technical reviews, licensing and permitting activities, and project-specific engineering studies and design work.

The Department of Energy has released its 2021 Climate Adaptation and Resilience Plan, outlining steps that it will take to ensure its facilities and operations adapt to and are increasingly resilient to the impacts of a changing climate. As announced by the White House last week , the DOE was one of more than 20 federal agencies to release climate change plans, which were developed in response to President Biden’s executive order on tackling the climate crisis, issued in January.

If you’re hearing for the first time that October 8 is Hydrogen Day, you might be wondering, “Why October 8?” and “What’s the connection to nuclear?”

ANS Nuclear Newswire has the answers.

Arizona Public Service is the latest nuclear utility with confirmed plans to install hydrogen production capacity, an investment decision that is based on analysis conducted under the Department of Energy’s H2@Scale program and backed by a $20 million DOE award.

By 2030, Kairos Power aims to demonstrate electricity production from a full-scale, 140-MWe fluoride salt–cooled high-temperature reactor, the KP-X. In service of that goal, Kairos plans to demonstrate Hermes, a scaled-down 35-MWth nonpower reactor, in Oak Ridge, Tenn.

Hermes is being built to “prove our ability to deliver affordable nuclear heat,” said Mike Laufer, Kairos Power chief executive officer and cofounder, as he explained Kairos’s plans to the local community during a September 28 webinar now available to view on demand. Laufer took questions, and Kairos took the opportunity to introduce a virtual open house that visitors can tour to view videos and interactive features and even submit comments.

Back in July, officials from the state of Tennessee and Kairos Power met in Nashville to celebrate Kairos’s plans to construct a low-power demonstration reactor in the East Tennessee Technology Park in Oak Ridge, Tenn. The demonstration facility is a scaled-down version of Kairos’s Fluoride Salt–Cooled High Temperature Reactor (KP-FHR), dubbed Hermes. The company first announced plans in December 2020 to redevelop the ETTP’s former K-33 gaseous diffusion plant site for construction of Hermes.

For years, pressure has been building for a commercial path to a stable supply of high-assay low-enriched uranium (HALEU)—deemed essential for the deployment of advanced power reactors—but advanced reactor developers and enrichment companies are still watching and waiting. In contrast, the uranium spot price soared after Sprott Physical Uranium Trust, a Canadian investment fund formed in July, began buying up U3O8 supplies, causing the price to increase over 60 percent, topping $50 per pound for the first time since 2012. Fueled by growing acknowledgment that nuclear power is a necessary part of a clean energy future, uranium is the focus of attention from Wall Street to Capitol Hill.

Plans to test a prototype mobile microreactor designed to military requirements moved ahead when the Department of Defense (DOD), acting through its Strategic Capabilities Office and with the Department of Energy serving as a cooperating agency, on September 16 announced the availability of a draft environmental impact statement for the construction and demonstration phase of Project Pele.

Paul Dabbar, former undersecretary for science at the Department of Energy and distinguished visiting fellow at Columbia University’s Center on Global Energy Policy, is lauding the recent successful test of a 10-ton high-temperature superconducting magnet performed by researchers at the Massachusetts Institute of Technology and Commonwealth Fusion Systems. In an op-ed published on September 10 in The Hill, Dabbar calls for a new level of investment and support for the commercial fusion sector.

In an op-ed published online yesterday in The Hill, Ted Nordhaus and Adam Stein of the Breakthrough Institute pick apart arguments made against funding for the construction of the Versatile Test Reactor at Idaho National Laboratory. Nordhaus and Stein contend that opposition to the VTR has been led by “entrenched opponents of nuclear energy” who “fear that innovation of the sort that many U.S. nuclear startups are presently betting on might give the technology a second life.”

The Center for Advanced Energy Studies (CAES) has announced the opening of the Small Modular Reactor Simulator Laboratory, featuring NuScale Power’s Energy Exploration Center, at its headquarters in Idaho Falls, Idaho. The new lab will increase CAES’s capabilities to train future scientists, engineers, and members of the energy workforce and will be used to educate the public about nuclear energy and reactor technology, according to an August 31 CAES press release.

Over the past decade, the Department of Energy has been collecting data on nuclear power plants to help plan for the eventual removal of spent nuclear fuel from the sites, performing site evaluations to assess transportation infrastructure and the transportability of spent fuel.

Researchers at Sandia National Laboratories have been expanding MELCOR—the severe accident modeling computer code used by the Nuclear Regulatory Commission to evaluate the safety of light water reactors—to study the small modular reactors and non-light-water advanced reactors that are under development. An article published in Sandia Lab News on August 27 describes in detail how MELCOR is being expanded to work with different reactor geometries, fuel types, and coolant systems.
