Our advice, when there’s no guidebook, no proven vehicle, and your destination is a moving target? Don’t forget to pack your nuclear power bank.

Physicist Andrea “Annie” Kritcher’s dedication to fusion target design has earned her a spot on the TIME100 Most Influential People list for 2023. Today, Kritcher and 99 other individuals on that list—among them Elon Musk, King Charles, Judy Blume, Patrick Mahomes, Beyoncé, Lionel Messi, Janet Yellen, and MrBeast—are being honored at the TIME100 Summit and Gala at the Lincoln Center in New York City.

The DIII-D National Fusion Facility in San Diego, Calif., has completed a monthlong research campaign using a negative triangularity plasma configuration inside its fusion tokamak and produced initial data that “appear very encouraging,” according to an April 24 news release from General Atomics (GA), which operates the Office of Science user facility on behalf of the Department of Energy. Full experimental results on “the highest-powered negative triangularity experiments in the history of the U.S. fusion research program” are expected this summer, according to GA.

Small modular reactor developer Holtec International and Energoatom, Ukraine’s nuclear plant operator, signed a cooperation agreement last Friday that envisions the construction of up to 20 of the American firm’s SMR-160 units in Ukraine, with grid connection for the pilot project achieved by March 2029. In addition, the agreement calls for building a Ukrainian manufacturing facility to localize the production of equipment required for SMR-160 construction.

Canada’s Cameco and U.K.-based Urenco last week jointly announced the signing of agreements to become part of a Westinghouse-led fuel supply chain for Bulgaria’s Kozloduy nuclear power plant. (Also included in the partnership is Uranium Asset Management.)

Seattle’s Ultra Safe Nuclear (USNC) has announced a partnership with two South Korean firms—Hyundai Engineering and SK ecoplant—for research and development on carbon-free hydrogen production. The three companies signed a memorandum of understanding on April 20 regarding the construction of a “hydrogen micro hub” at SK ecoplant’s headquarters in Seoul’s Jongno-gu district.

A refurbished hot cell laboratory is allowing the Department of Energy’s Brookhaven National Laboratory to streamline the production and shipment of actinium-225 to support clinical trials of cancer therapies.

Here is a recap of industry happenings over the past months:

ADVANCED REACTOR MARKETPLACE

Ultra Safe and Framatome reach TRISO agreement

Ultra Safe Nuclear and Framatome have signed a nonbinding agreement to manufacture commercial quantities of TRISO fuel for advanced reactor designs, including USNC’s Micro Modular Reactor. It is expected that the manufacturing of both TRISO fuel particles and USNC’s fully ceramic microencapsulated fuel will begin in late 2025, with production capacity being made available to the broader global commercial market. At-scale production lines for these materials have been demonstrated at USNC’s Pilot Fuel Manufacturing facility in Oak Ridge, Tenn., the first privately funded producer of TRISO fuel particles in the United States.

Westinghouse Electric Company has signed an agreement with engineering firm Tecnatom and training/consulting services provider Accelerant Solutions to launch a nuclear training program for utilities in the United States and Canada. (Westinghouse completed a 50 percent acquisition of Spain-based Tecnatom in March of last year.)

The program—the Nuclear Excellence Academy (NEXA)—will combine Westinghouse and Accelerant Solutions’ industry expertise with Tecnatom’s digital products and services to provide in-person, digital, and on-demand training for nuclear personnel, according to an April 18 Westinghouse announcement.

Under the Radioisotope Power Systems Program, NASA and the Department of Energy have been advancing a novel radioisotope power system (RPS) based on dynamic energy conversion. This approach will manifest a dynamic RPS (DRPS) option with a conversion efficiency at least three times greater than a thermoelectric-based RPS. Significant progress has recently been made toward this end. A one-year system design phase has been completed by NASA industry partner Aerojet Rocketdyne, which resulted in a DRPS with power of 300 watts-electric (W_e) with convertor-level redundancy. In-house technology development at the NASA Glenn Research Center (GRC) has demonstrated the conversion devices in relevant environments and has shown all requirements can be met. Progress has also been made on the control electronics necessary for dynamic energy conversion. Flight-like controllers were recently upgraded and achieved an 11-percentage-point increase in efficiency. Control architectures have been developed to handle the multiconvertor arrangements in the latest DRPS design. A system-level DRPS testbed is currently being assembled that will experimentally demonstrate the DRPS concept being pursued.

The Korea Atomic Energy Research Institute (KAERI) and the government of Alberta have agreed on a comprehensive cooperation framework to explore the viability of using small modular reactors to help decarbonize the province—Canada’s biggest energy producer and its biggest polluter. The announcement comes the same week that Alberta’s United Conservative Party government released a climate plan aimed at reaching net zero by 2050.

The Canadian Nuclear Safety Commission (CNSC) has completed phase two of its prelicensing vendor design review for Terrestrial Energy’s Integral Molten Salt Reactor (IMSR), the Ontario-based advanced nuclear technology firm announced Tuesday. Phase one of the VDR commenced in April 2016 and was completed in November of the following year.

A civil nuclear fuel security agreement between the five nuclear leaders of the G7—announced on April 16 on the sidelines of the G7 Ministers’ Meeting on Climate, Energy and Environment in Sapporo, Japan—establishes cooperation between Canada, France, Japan, the United Kingdom, and the United States to flatten Russia’s influence in the global nuclear fuel supply chain.

In the new year, ANS launched Trustees of Nuclear, a corporate partnership program ANS executive director/chief executive officer Craig Piercy announced in the January issue of Nuclear News (p. 25). The goal of Trustees of Nuclear is to directly support ANS’s programs aimed at improving nuclear literacy, like the Society’s K-12 nuclear STEM activities, public engagement, and discussions with policymakers. As the main professional organization for the whole nuclear discipline, ANS is in a unique position to unite leaders in the nuclear community to focus on these long-term programs and help the country realize the full potential of the atom.

Germany may have walked away from nuclear energy, but just across the border, Poland continues to stride confidently toward it.

After solidifying plans in February for deploying Westinghouse’s AP1000 reactors in Poland, Polskie Elektrownie Jądrowe (PEJ) on April 13 submitted an application to the Ministry of Climate and Environment for a decision-in-principle regarding the nation’s initial nuclear project—construction of an AP1000 plant at a site some 40 miles northwest of Gdansk, the capital of Poland’s Pomeranian province.

The Nuclear Regulatory Commission announced on April 14 that it will regulate fusion energy systems using a framework based on the agency’s 10 CFR Part 30 process for licensing byproduct material facilities—such as particle accelerators—rather than 10 CFR Parts 50 and 52, which are used to license utilization facilities like fission power reactors. The commission’s decision means that future fusion energy facilities could be regulated by Agreement States acting with guidance from the NRC.

G7 governments should support life extension for today’s power reactor fleet, restart operable units, and accelerate the deployment of advanced reactors, states a joint declaration issued April 16 at the Nuclear Energy Forum, a first-of-its-kind colloquy held on the margins of the G7 Ministers’ Meeting on Climate, Energy and Environment in Sapporo, Japan.

Long-duration missions with limited solar exposure need a reliable power source to operate. This makes nuclear power sources (NPSs) an attractive alternative to solar energy for such missions. The implementation of the ESA Safety Policy on the Use of Nuclear Power Sources by the European Space Agency’s Independent Safety Office (ISO) provides a framework for ensuring the safe use of NPSs and sets a standard for future ESA missions. This article provides an overview of how the ISO is implementing the policy in the development and operation of the Argonaut mission, which serves as a valuable case study for understanding the practical application of the ESA safety policy and the importance of ensuring the safe use of NPSs in space.

Ignoring a last-minute plea from a long list of scientific luminaries (including Nobel laureate Steven Chu and climate scientist James Hansen) to reconsider, as well as recent polls showing pronuclear sentiment among a majority of its population, Germany shut down its last three operating nuclear power plants late Saturday, ending 60-plus years of electricity generation from fission. (Germany’s first nuclear power plant, Kahl, was commissioned in 1961 and closed in 1985.)
