Argonne National Laboratory has added a new twist to digital twin technology for research into nuclear energy. According to Rui Hu, a principal nuclear engineer at Argonne, “Our digital twin technology introduces a significant step toward understanding and managing advanced nuclear reactors, enabling us to predict and respond to changes with the required speed and accuracy.”
The research of Hu and his colleagues, “Development of Whole System Digital Twins for Advanced Reactors: Leveraging Graph Neural Networks and SAM Simulations,” was published in the American Nuclear Society journal Nuclear Technology.
Virtual representation: A digital twin technology is an accurate virtual representation of a complex system. It is updated with real-time data from sensors applied to the physical system, such as a nuclear reactor.

Oklo announced last week that it hopes to expand development and global deployment of its advanced nuclear technology through a new partnership with Korea Hydro & Nuclear Power.
The memorandum of understanding includes plans for the companies to advance standard design development and global deployment of Oklo’s planned Aurora Powerhouse, a microreactor that would generate 15 MW and be scalable to 50 MWe. Oklo said each unit can operate for 10 years or longer before refueling.
Oklo and KHNP plan to cooperate on early-stage project development, including manufacturability assessments and planning of major equipment, supply chain development for balance-of-plant systems, and constructability assessments and planning.

NuScale earned approval for its “larger” US460 77-MWe small modular reactor plant design, the Nuclear Regulatory Commission announced last week.
The standard design approval (SDA) is a determination by NRC staff that a reactor design meets the agency’s applicable design requirements, and companies can reference it when applying for a license to build and operate the reactor—but it does not ensure license approval from the commission.
Tokyo Electric Power Company has released the results of its initial analysis of a sample of nuclear fuel debris from Unit 2 of Japan’s damaged Fukushima Daiichi nuclear power plant. The sample, which measured around 5mm by 4mm and totaled 0.187 grams, was taken from the floor of the reactor pedestal during a second trial removal of fuel debris conducted in April.
The use of nuclear fission power and its role in impacting climate change is hotly debated. Fission advocates argue that short-term solutions would involve the rapid deployment of Gen III+ nuclear reactors, like Vogtle-3 and -4, while long-term climate change impact would rely on the creation and implementation of Gen IV reactors, “inherently safe” reactors that use passive laws of physics and chemistry rather than active controls such as valves and pumps to operate safely. While Gen IV reactors vary in many ways, one thing unites nearly all of them: the use of exotic, high-temperature coolants. These fluids, like molten salts and liquid metals, can enable reactor engineers to design much safer nuclear reactors—ultimately because the boiling point of each fluid is extremely high. Fluids that remain liquid over large temperature ranges can provide good heat transfer through many demanding conditions, all with minimal pressurization. Although the most apparent use for these fluids is advanced fission power, they have the potential to be applied to other power generation sources such as fusion, thermal storage, solar, or high-temperature process heat.1–3

The Palisades nulear power plant received a final “clean bill” of environmental assessment impact from the Nuclear Regulatory Commission today.
The findings of the NRC staff's EA showed no significant environmental impact for the Covert, Mich., plant, which plans to restart after operations were halted three years ago this month due to economic hardships in the energy market.
Here is a recap of industry happenings from the recent past:
DOD selects companies for its installations microreactor program
The Department of Defense has selected eight technology companies as being eligible to seek funding for developing microreactor technologies as part of the DOD’s Advanced Nuclear Power for Installations program. That program seeks to “design, license, build, and operate one or more microreactor nuclear power plants on military installations . . . to support global operations across land, air, sea, space, and cyberspace.” The selected companies are Antares Nuclear, BWXT Advanced Technologies, General Atomics Electromagnetic Systems, Kairos Power, Oklo, Radiant Industries, Westinghouse Government Services, and X-energy. Specific objectives of the DOD program are to “field a decentralized scalable microreactor system capable of producing enough electrical power to meet 100 percent of all critical loads” and to “utilize the civil regulatory pathways of the Nuclear Regulatory Commission to stimulate commercial nuclear microreactor technology development and the associated supply chains in the U.S.”
The owners of the two-unit Hatch nuclear power plant are hoping to operate the facility for up to 80 years. Southern Nuclear submitted its application this month to the Nuclear Regulatory Commission for a subsequent license renewal for the dual-unit plant in Baxley, Ga.
The SLR seeks to extend the operating licenses of both boiling water reactors at Hatch from 60 to 80 years. The NRC approved the plant’s first 20-year license renewal in January 2002, which extended Unit 1’s license through August 6, 2034, and Unit 2’s through June 13, 2038.
