The Defense Logistics Agency Energy (DLA Energy) has selected Oklo Inc. as the pending contractor awardee to site a microreactor at Alaska’s Eielson Air Force Base, the advanced reactor firm announced this morning. Eielson is located on 63,195 acres in central Alaska, 26 miles southeast of Fairbanks.

Speaking at an event last week at the University of Illinois–Urbana-Champaign, Illinois Gov. J. B. Pritzker defended his recent veto of S.B. 76—the bipartisan bill that would have lifted the state’s decades-old moratorium on nuclear plant construction. At the same time, he extolled the promise of small modular reactors and said he would sign an amended version of the legislation.

A Government Accountability Office report released last week on the Nuclear Regulatory Commission’s preparedness to review and approve advanced reactor applications finds—to scant surprise from nuclear advocates—room for improvement.

The 48-page report, Nuclear Power: NRC Needs to Take Additional Actions to Prepare to License Advanced Reactors, had been requested in February 2022 by two prominent Capitol Hill supporters of the technology—Sen. Shelley Moore Capito (R., W.Va.), ranking member of the Senate Environment and Public Works Committee, and Rep. Cathy McMorris Rodgers (R., Wash.), chair of the House Energy and Commerce Committee.

Texas Gov. Greg Abbott sat down with X-energy chief executive officer Clay Sell and Dow chair and CEO Jim Fitterling last week for a “fireside chat” at the University of Texas–Austin on the role of nuclear energy and technology in the state.

Duke Energy has filed an update to its 2022 state-mandated carbon-reduction plan with the public utility commissions of North and South Carolina, proposing the deployment of small modular reactors at the Belews Creek coal plant in Stokes County, N.C., which is slated for retirement next decade. A similar system would be added at a second site yet to be determined for a total of 600 MW of advanced nuclear. (Both the advanced reactor production tax credit and investment tax credit included in last year’s Inflation Reduction Act offer a 10 percent bonus for facilities sited in certain energy communities, including those with retiring coal plants.)

Rezin

Pritzker

Nuclear advocates may have applauded Illinois Gov. J.B. Pritzker two years ago when he signed legislation providing $694 million to three of the state’s struggling nuclear power plants, but they’re hissing him now: On Friday, Pritzker vetoed S.B. 76, a bill that would have lifted the state’s decades-old moratorium on new nuclear power plant construction.

Introduced in January by Sen. Sue Rezin (R., 38th Dist.), S.B. 76 called for deleting language in the Illinois Public Utilities Act that forbids nuclear plant construction in the state until the Illinois Environmental Protection Agency determines that the federal government “has identified and approved a demonstrable technology or means for the disposal of high-level nuclear waste, or until such construction has been specifically approved by a statute enacted by the General Assembly.”

Advanced nuclear technology firm TerraPower announced today the selection of four suppliers to support its Natrium reactor demonstration project, in development near a retiring coal plant in Kemmerer, Wyo.

In an 86–11 vote yesterday, the Senate passed the fiscal year 2024 National Defense Authorization Act (NDAA), and with it, the Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy (ADVANCE) Act.

Introduced March 30 by the senatorial trio of Shelley Moore Capito (R., W.Va.), Tom Carper (D., Del.), and Sheldon Whitehouse (D., R.I.), The ADVANCE Act was endorsed by the Environment and Public Works Committee in May in a bipartisan 16–3 vote and was made part of the annual must-pass NDAA earlier this month.

On July 14, the House narrowly passed (219–210) its own version of the NDAA, containing several controversial amendments pushed by GOP conservatives. The two chambers are now faced with reconciling the two measures and producing a compromise version that can be sent to President Biden’s desk.

The Japanese government has chosen Mitsubishi Heavy Industries (MHI) to head up the conceptual design and research and development of a demonstration sodium-cooled fast reactor, the Tokyo-based engineering firm announced recently.

MHI is to oversee the work in partnership with Mitsubishi FBR Systems Inc. (MFBR), an MHI Group engineering company established in 2007 to develop and design fast breeder reactors.

Conceptual design work is scheduled to commence in fiscal year 2024, with operation of the unit slated for the 2040s.

Reactor roadmap: According to MHI’s announcement, in the strategic roadmap for fast-reactor development adopted by the Japanese Cabinet in December 2018, a policy was defined to assess the efficacy of several types of technologies to be developed following a competition among private-sector companies. The roadmap was subsequently revised by the Cabinet in December 2022, at which time two decisions were made: (1) to select a sodium-cooled fast reactor as the target of the conceptual design of the demonstration unit and (2) to select a manufacturer to serve as the core company in charge of the reactor’s design and requisite R&D.

The Nuclear Regulatory Commission and Poland’s National Atomic Energy Agency (PAA) have renewed their cooperation agreement for the next five years.

The Nuclear Regulatory Commission staff has completed its final safety evaluation for Kairos Power’s application to build its Hermes advanced test reactor at a site in Oak Ridge, Tenn., the agency announced recently. The evaluation found no safety aspects precluding issuance of a construction permit for the proposed reactor.

Santa Clara, Calif.–based Oklo is planning to build its second and third commercial Aurora Powerhouse nuclear plants in southern Ohio, the company announced yesterday. The advanced reactor developer received a site permit in December 2019 from the Department of Energy to build its initial Aurora facility at Idaho National Laboratory.

According to the announcement, Oklo has signed an agreement with the Southern Ohio Diversification Initiative (SODI), a community-reuse organization, to deploy two 15-MWe plants on land owned by SODI at the Portsmouth site near Piketon, Ohio. The DOE began transferring parcels of the Portsmouth site—home to the Portsmouth Gaseous Diffusion Plant, now undergoing decontamination and decommissioning—to SODI in June 2018 for economic development.

Ontario–based Terrestrial Energy announced yesterday that its U.S. branch has been awarded a regulatory assistance grant from the Department of Energy to support the company’s Nuclear Regulatory Commission licensing program for the Integral Molten Salt Reactor (IMSR) plant.

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.

The White House’s recently released budget request for fiscal year 2024 would provide $1.006 billion in gross budget authority for the Nuclear Regulatory Commission—an increase of $63.2 million, or about 6.7 percent, from the enacted FY 2023 level. According to the agency, the boost is largely for increased salaries and benefits “consistent with the Office of Management and Budget guidance.”

Westinghouse Electric Company has filed a notice of intent to submit key licensing reports for its eVinci microreactor to the Nuclear Regulatory Commission and Canadian Nuclear Safety Commission for joint review, the firm announced last week. (The two nuclear regulators signed a memorandum of cooperation in August 2019 to increase collaboration on the technical reviews of advanced reactor and small modular reactor technologies.)

The Canadian Nuclear Safety Commission (CNSC) and Poland’s National Atomic Energy Agency (PAA) have signed a memorandum of cooperation to share best practices and experience in reviewing advanced and small modular reactor technologies. (The two agencies are already engaged in cooperation on nuclear safety matters under a memorandum of understanding inked in 2014.)

Kairos Power, an Alameda, Calif.–based advanced reactor developer, announced yesterday that it has been named to Cleantech Group’s list of the 100 most innovative and promising private companies in the cleantech sector for 2023. Cleantech Group is a research and consulting services firm headquartered in San Francisco.

Duncan

Rep. Jeff Duncan (R., S.C.), a member of the House Energy and Commerce Committee, has issued a three-page “Blueprint for Nuclear Innovation and Competitiveness,” highlighting nuclear policy priorities in the areas of licensing and regulatory modernization, financing, and fuel (including used fuel). According to a press release from Duncan’s office, the document aims “to help chart the course for the nuclear energy agenda in the next Congress and facilitate policy discussions among both lawmakers and industry leaders.” Published last week—along with a related “Dear Colleague” letter—the blueprint is also, according to E&E News, “a sign of his ambitions for landing a more senior role with the committee,” including a subcommittee leadership position should the GOP gain control of the House in the next Congress.

Since at least June of last year—when TerraPower and PacifiCorp announced plans to site the Natrium reactor demonstration project at one of Wyoming’s retiring coal plants—the concept of repurposing those plants to host nuclear reactors has been a popular topic of conversation among the energy cognoscenti.
