Sweden’s parliament, the Riksdag, has approved legislative amendments from Prime Minister Ulf Kristersson’s government that will remove the country’s prohibition on new reactor construction at sites other than Sweden’s three current nuclear plants—Forsmark, Ringhals, and Oskarshamn—and do away with the limitation on the number of simultaneously operating reactors, currently capped at 10.

The amendments enter force on January 1.

“The Riksdag shares the government’s assessment that fossil-free electricity from nuclear power will also continue to play a role of central importance in the Swedish energy mix,” the legislative body said in a statement following the November 29 vote. “The main reasons for this are an expected greater demand for electricity in combination with the fact that fossil fuels have to be phased out, particularly for climate reasons. Nuclear power also contributes to the stable and predictable functioning of the Swedish power system.”

Framatome and Nuclearelectrica, operator of Romania’s Cernavoda nuclear power plant, announced the signing of a memorandum of understanding to explore the possibility of producing the medical isotope lutetium-177. The cooperative agreement was signed during the World Nuclear Exhibition 2023, held November 28–30 in Paris.

The development of modern nuclear reactor technologies relies heavily on complex software codes and computer simulations to support the design, construction, and testing of physical hardware systems. These tools allow for rigorous testing of theory and thorough verification of design under various use or transient power scenarios.

At the World Nuclear Exhibition in Paris this week, Ontario Power Generation announced contracts with Canadian, French, and U.S. companies to ensure a fuel supply for the first of four GE Hitachi Nuclear Energy BWRX-300 small modular reactors planned for deployment at OPG’s Darlington nuclear power plant.

World Nuclear Energy Day takes place tomorrow, marking the 81st anniversary of the day in 1942 when Enrico Fermi and his team achieved the first controlled, self-sustaining nuclear chain reaction with Chicago Pile-1. It also is the anniversary of the first commercial nuclear reactor reaching criticality—at Shippingport, Pa., on December 2, 1957.

While the featured speakers of the American Nuclear Society’s 2023 Winter Meeting and Expo opening plenary—West Virginia senators Shelley Moore Capito and Joe Manchin and Nuclear Regulatory Commission chair Christopher Hanson—generated a lot of buzz, the rest of the session provided constructive insights into the current state of nuclear technology and a glimpse of what the future may hold.

TerraPower and Uranium Energy announced today that they have signed a memorandum of understanding to “explore the potential supply of uranium” for TerraPower’s demonstration reactor in Kemmerer, Wyo.

Westinghouse Electric Company and Ontario Power Generation have signed a memorandum of understanding establishing a framework to identify potential areas of cooperation for the deployment of nuclear technologies in Canada, the companies jointly announced this morning. (While based in Cranberry Township, Pa., Westinghouse is owned by Canadian firms Brookfield Asset Management and Cameco.)

Savannah River Nuclear Solutions’ Supply Chain Management (SCM) team recently hosted its first staff augmentation summit to strengthen relationships with 25 staffing firms and provide upcoming process changes for fiscal year 2024.

The 2023 Materials in Nuclear Energy Systems (MiNES 2023) meeting will take place December 10–14 in New Orleans, La. The third installment of MiNES will focus on cutting-edge research in the fission reactor materials community.

Personnel from the Department of Energy’s Office of Environmental Management and the National Nuclear Security Administration recently gathered to discuss plans for the upcoming transfer of landlord responsibility for the Savannah River Site in South Carolina.

Framatome Inc. and Ultra Safe Nuclear Corp. (USNC) signed an agreement on November 28 at the World Nuclear Exhibition in Paris, France, establishing a joint venture to manufacture nuclear fuel for USNC’s gas-cooled microreactor and other advanced reactor designs. Working together, the companies plan to produce commercial quantities of TRISO fuel particles and USNC’s proprietary Fully Ceramic Microencapsulated (FCM) fuel, which contains TRISO fuel particles within a ceramic fuel pellet.

The Department of Energy plans to award one or more contracts to deconvert high-assay low-enriched uranium (HALEU) from its post-enrichment gaseous uranium hexafluoride (UF₆) state to other chemical forms, such as metal or oxide. The DOE’s final request for proposals (RFP) for deconversion services was issued November 28 as one part of the agency’s effort—under the HALEU Availability Program—to establish a reliable domestic supply of advanced reactor fuel. The DOE will store the deconverted material until it is required by a fuel fabricator or other end user.

The Nuclear Regulatory Commission announced that it will hold a hybrid public meeting on December 7 to discuss the license termination process and to accept comments on the remaining cleanup activities under the license termination plan for the Crystal River-3 nuclear power plant in Crystal River, Fla.

Saskatchewan premier Scott Moe yesterday announced C$80 million (about $59 million) for the Saskatchewan Research Council (SRC) to pursue demonstration of Westinghouse Electric Company’s eVinci microreactor technology.

Researchers at Idaho National Laboratory in early 2023 manufactured commercial-grade high-assay low-enriched uranium (HALEU) fuel pellets to the specifications of a General Electric accident tolerant fuel design, INL announced November 21. A team working at INL’s Experimental Fuels Facility at the Material and Fuels Complex fabricated about two dozen uranium dioxide pellets using HALEU enriched up to 15 percent U-235.

The United Kingdom has announced a new partnership with South Korea to accelerate the clean energy transition by strengthening cooperation on low-carbon technologies, domestic climate policies, and civil nuclear energy.

Signed November 22 in London by British energy security and net zero secretary Claire Coutinho and South Korean minister for trade, industry, and energy Moon Kyu Bang, the partnership promotes U.K.-South Korean business collaboration, addressing barriers to trade and encouraging mutual development of the two nations’ energy sectors.

Here is a recap of industry happenings from the recent past:

ADVANCED REACTOR MARKETPLACE

Centrus-Oklo partnership expands

Oklo, a California-based developer of next-generation fission reactors, has expanded its partnership with Centrus Energy, a Maryland-based supplier of nuclear fuel and services. The two companies have been cooperating since 2021 on the development of Centrus’s American Centrifuge Plant in Piketon, Ohio, to produce high-assay low-enriched uranium (HALEU) fuel. According to the companies’ new memorandum of understanding, Centrus will manufacture certain components for Oklo’s Aurora “powerhouse” reactor, a fast neutron reactor designed to generate up to 15 MW of power and operate for at least 10 years without refueling. The Aurora is also designed to produce usable heat. Centrus also has agreed to purchase electricity generated by the Aurora reactors, while Oklo has agreed to purchase HALEU fuel from the Piketon facility. The facility is expected to begin fuel production before the end of the year.

A notice of opportunity from the Nuclear Regulatory Commission was published in the November 22 Federal Register to intervene in an adjudicatory hearing on Kairos Power’s application for a construction permit to build the Hermes 2 test reactor facility in Oak Ridge, Tenn.

Commissioning has begun on a new large-scale ventilation system at the Waste Isolation Pilot Plant in New Mexico.

The Safety Significant Confinement Ventilation System (SSCVS) is expected to increase underground airflow from 170,000 cubic feet per minute up to 540,000 cfm. The increased airflow will allow for simultaneous underground waste emplacement, mining, and ground control work. Ground control, including bolting, controls the movement of salt rock—known as salt creep—in the WIPP underground.
