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

ADVANCED REACTOR MARKETPLACE

International SMR collaboration launched

The nine member states of the International Nuclear Regulators’ Association (INRA)—Canada, France, Germany, Japan, South Korea, Spain, Sweden, the United Kingdom, and the United States—have agreed to collaborate on the generic design assessment and licensing of small modular reactor technologies. According to a statement released by the organization, the internationally standardized reactor designs would aid in the facilitation of efficient regulatory reviews, although local issues such as siting and environmental factors must be addressed by national regulatory agencies. The INRA members expressed their support for the International Atomic Energy Agency’s Nuclear Harmonisation and Standards Initiative, but they stressed that independent, national regulatory reviews should not be replaced by an international approach.

Polskie Elektrownie Jądrowe (PEJ), the state-owned firm set up to lead Poland’s efforts to establish a civil nuclear power program, signed an agreement yesterday with the Warsaw University of Technology to cooperate on the training of personnel for the nuclear sector.

The agreement provides for “substantive and research cooperation” as well as “cooperation in the development and implementation of scholarship programs [and] co-organization of competitions for scientific works or design competitions,” PEJ said in a news release. PEJ and the university will also work together on a curriculum to enable graduates to gain the knowledge and skills necessary to find employment in the nuclear energy field, the company added.

According to Poland’s Ministry of Climate and Environment, there are already some 80 companies operating in the Central European nation that provide services to nuclear technology vendors worldwide, with another 300 ready to join the nuclear supply chain.

Three college interns from the Savannah River Site were the keynote speakers at a recent Up & Atom Breakfast hosted by Citizens for Nuclear Technology Awareness (CNTA). The breakfast was held at Newberry Hall in Aiken, S.C.

In Big Bang nucleosynthesis (BBN), the deuterium-tritium (DT) fusion reaction ³H(d,n)⁴He, enhanced by the 3/2⁺ “Bretscher resonance,” is responsible for 99 percent of primordial helium-4. While this fact has been known for decades, it has not been widely appreciated. The importance of the resonant nature of the DT fusion reaction has been amplified by recent activities related to the production and use of terrestrial fusion, including the recent net-gain shot at the National Ignition Facility (NIF). Here, we aim to highlight the anthropic importance of the ⁴He-producing DT reaction that plays such a prominent role in models of nucleosynthetic processes occurring in the early universe. This primordial helium serves as a source for the subsequent creation of more than 25 percent of the carbon (¹²C) and other heavier elements that compose a substantial fraction of the human body. Further studies are required to determine a better characterization of the amount of ¹²C than this lower limit of 25 percent. Some scenarios of core stellar nucleosynthetic yield of ¹²C suggest that even higher percentages of carbon from primordial helium are possible.

Canadian nuclear tech firm Terrestrial Energy has signed a manufacturing and supply contract with Springfields Fuels Limited—a Britain–based subsidiary of Westinghouse Electric Company—for the design and construction of an Integral Molten Salt Reactor (IMSR) fuel pilot plant.

In an August 3 press release, Terrestrial said that Springfields’ reactor fuel manufacturing facility has extensive existing infrastructure available to support the fuel supply for IMSR development and is scalable to support a fleet of IMSR plants operating in the 2030s. Located near Preston, Lancashire in northwestern England, the Springfields facility is the only site in the United Kingdom for nuclear fuel manufacturing.

Type One Energy Group, a Madison, Wis. –based stellarator fusion energy company, announced the opening of new offices in Oak Ridge, Tenn., during the East Tennessee Economic Council’s fifth annual NOW Conference, held August 1–2 in Knoxville.

Type One Energy’s expansion into Oak Ridge follows the company’s recent funding of an oversubscribed seed round of $29 million. The company is also one of eight fusion developers that was selected by the Department of Energy in late May to receive a total of $46 million in funding to kick off the public-private Milestone-Based Fusion Development Program, aimed at developing fusion pilot plant designs.

The U.K. government recently confirmed a further £170 million (about $216 million) investment of previously allocated funding for development work on the proposed Sizewell C nuclear power plant project in Suffolk, England.

Coons

Budd

A bipartisan coalition of 15 senators led by Sens. Ted Budd (R., N.C.) and Chris Coons (D., Del.) is backing a resolution declaring that “in order to maintain geopolitical energy leadership, reduce carbon emissions, and enhance the energy security of the United States, the Senate is committed to embracing and promoting nuclear power as a clean baseload energy source necessary to achieve a reliable, secure, and diversified electric grid.”

The resolution, S. Res. 321, was introduced July 27 and referred to the Energy and Natural Resources Committee.

Fellow fission fans: Cosponsors of S. Res. 321 include Sens. Cory Booker (D., N.J.), Sherrod Brown (D., Ohio), Kevin Cramer (R., N.D.), Mike Crapo (R., Idaho), Lindsey Graham (R., S.C.), Mark Kelly (D., Ariz.), Joe Manchin (D., W.Va.), Pete Ricketts (R., Neb.), Jim Risch (R., Idaho), Kyrsten Sinema (I., Ariz.), Thom Tillis (R., N.C.), Mark Warner (D., Va.), and Roger Wicker (R., Miss.).

SHINE Technologies, a Wisconsin-based medical isotopes and fusion technology company, announced today that it has demonstrated clearly visible Cherenkov radiation produced by fusion for what is believed to be the first time in history. Cherenkov radiation is the characteristic blue glow typically seen in underwater fission reactions.

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.

The Nuclear Regulatory Commission has accepted for formal review NuScale Power’s standard design approval (SDA) application for its updated small modular reactor design, the Portland, Ore.–based firm announced yesterday.

The Department of Energy today released its final environmental assessment (EA) and a proposed finding of no significant impact (FONSI) for the design, construction, and operation of the Molten Chloride Reactor Experiment (MCRE) at Idaho National Laboratory. The draft EA was released earlier this year, in March, for four weeks of public comments.

Dozens of students from the Savannah River Nuclear Solutions (SRNS) Internship Program were recently offered a chance at full-service positions during what SRNS called a signing day event held at the Department of Energy’s Savannah River Site, near Aiken, S.C.

CFPP LLC, the limited liability company established by Utah Associated Municipal Power Systems (UAMPS) in 2020 to bring its Carbon Free Power Project to fruition, has applied to the Nuclear Regulatory Commission for a limited work authorization (LWA) to permit certain early project construction activities prior to the issuance of a combined license (COL). In a July 31 news release, CFPP said that should its application be approved, early-scope construction on the small modular reactor project would likely begin in mid-2025.

The Department of Energy’s Office of Environmental Management awarded a contract to Aptim Federal Services of Baton Rouge, La., to perform deactivation, decommissioning, and removal of the former Ion Beam Facility at Los Alamos National Laboratory in New Mexico.

Helling

Terry

The relatively young pedagogical field of mind, brain, and education (MBE) is being increasingly applied to training programs in the nuclear industry. Last month, this column highlighted how the MBE approach is being used at the Beaver Valley nuclear power plant in Shippingport, Pa. (“Neuroscience meets nuclear science at Beaver Valley,” NN, June 2023, p. 80). This month, the focus is on the MBE efforts of Pittsburgh-­based Westinghouse Electric Company, led by Westinghouse employees Pamela Terry, business and staff development lead, and Dave Helling, senior training advisor.

Helling was one of four panelists (along with Beaver Valley’s instructional technologist Annaliese Piraino) who participated in a discussion at the Conference on Nuclear Training and Education: A Biennial International Forum (CONTE 2023) earlier this year. There, he summarized his two conference presentations and discussed aspects of his company’s psychology-­ and neuroscience-­based approach to training and education.

To the ears of the nuclear community, the news from Georgia Power this morning may sound a bit like “Ode to Joy” from Beethoven’s Ninth: After years of delay, Unit 3 at the Vogtle nuclear power plant has entered commercial operation, becoming the first newly constructed power reactor in the United States in more than 30 years and the nation’s first Westinghouse-supplied Generation III+ AP1000 unit to be placed into service. The new unit joins Vogtle-1 and -2—1,169-MWe four-loop pressurized water reactors that entered commercial operation in the late 1980s.

The Nuclear Regulatory Commission has authorized Southern Nuclear Operating Company to begin loading fuel into Unit 4 at the Vogtle nuclear expansion site near Waynesboro, Ga., making the unit the second reactor to reach this milestone in the agency’s combined license process—a little less than one year after Vogtle-3. (Prior to 1989, reactors were licensed under a two-step process, requiring both a construction permit and an operating license.)

The Nuclear Regulatory Commission reported on July 27 that it has issued a license to Rare Element Resources Inc. for a proposed pilot project in Wyoming to demonstrate a proprietary process to extract rare earth elements from ore.

Sometimes, even with decades of research and testing, a project never gets off the ground. That has been the case for U.S. nuclear thermal rockets—so far. Research began in the 1950s and peaked with a series of rigorous ground tests for NERVA—the Nuclear Engine for Rocket Vehicle Applications—before the program was canceled in 1973. Five decades on, this technology has yet to make it to the launchpad. But while mission priorities shift, the physics is solid: Fission-powered nuclear thermal rockets (NTRs) still offer two to five times greater efficiency than conventional rockets.
