The New Mexico Environment Department (NMED) is adding several conditions to the operating permit for the Department of Energy’s Waste Isolation Pilot Plant (WIPP) near Carlsbad, N.M. The permit changes, which would prioritize the disposal of transuranic (TRU) waste generated in the state and limit the repository’s capacity, are contained in a fact sheet the NMED.

It’s official: Early in the morning on December 5 at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), the laser-triggered implosion of a meticulously engineered capsule of deuterium and tritium about the size of a peppercorn yielded, for the first time on Earth, more energy from a fusion reaction than was delivered to the capsule. The input of 2.05 megajoules (MJ) to the target heated the diamond-shelled, spherical capsule to over 3 million degrees Celsius and yielded 3.15 MJ of fusion energy output. The achievement was announced earlier today by officials and scientists representing the Department of Energy and its National Nuclear Security Administration, the White House, and LLNL during a livestreamed event.

Construction of a backup load-in station has been completed at the Hanford Site’s Effluent Treatment Facility (ETF) in Washington state.

“We broke ground on the backup facility about a year ago,” said Rob Wood, project manager for Washington River Protection Solutions, the Department of Energy’s tank operations contractor at the site. “I am proud of the team for completing this portion of the load-in expansion project and doing it safely. In phase two, expansion of the main load-in station will prepare us for 24/7 operations on the Hanford Site.”

The Department of Energy’s Office of Nuclear Energy announced December 7 that its new HALEU Consortium is open for membership. And not just from U.S. enrichers, fuel fabricators, and others working in the front-end fuel cycle, but from “any U.S. entity, association, and government organization involved in the nuclear fuel cycle,” and—at the DOE’s discretion—“organizations whose facilities are in ally or partner nations.” The HALEU Consortium will essentially serve as an information clearinghouse to meet DOE-NE’s ongoing needs for firm supply and demand data as it supports the development of a commercial domestic high-assay low-enriched uranium (HALEU) infrastructure to fuel advanced reactors. The consortium is open for business almost one full year after the DOE first requested public input on its structure.

ANS will host a members-only event on December 7 from 1:00 to 2:00 p.m. EST with Jigar Shah, director of the Department of Energy’s Loan Programs Office (LPO). Craig Piercy, ANS executive director and chief executive officer, will lead the interview.

Register now: Hear about the ambitious goals of the Biden administration to decarbonize the power sector by 2035, which were highlighted in Shah’s article in the November issue of Nuclear News. Shah will also discuss how nuclear can be an important part of the decarbonized energy mix in the United States and how he believes the LPO can support the administration’s target.

Centrus Energy confirmed on December 1 that its wholly owned subsidiary American Centrifuge Operating signed a contract with the Department of Energy, which was first announced on November 10, to complete and operate a demo-scale high-assay low-enriched uranium (HALEU) gaseous centrifuge cascade.

Whether commercial demand for high-assay low-enriched uranium (HALEU) fuel ultimately falls at the high or low end of divergent forecasts, one thing is certain: the United States is not ready to meet demand, because it currently has no domestic HALEU enrichment capacity. But conversations happening now could help build the commercial HALEU enrichment infrastructure needed to support advanced reactor deployments. At the 2022 American Nuclear Society Winter Meeting, representatives from three potential HALEU enrichers, the government, and industry met to discuss their timelines and challenges during “Got Fuel? Progress Toward Establishing a Domestic US HALEU Supply,” a November 15 executive session cosponsored by the Nuclear Nonproliferation Policy Division and the Fuel Cycle and Waste Management Division.

At a moment of global crisis, in a windowless squash court below the football stadium bleachers at the University of Chicago, a group of scientists changed the world forever.

On December 2, 1942, a team of researchers led by Enrico Fermi, an Italian refugee, successfully achieved the world’s first human-­created, self-­sustaining nuclear chain reaction. Racing to beat Nazi Germany to the creation of an atomic weapon, the team of researchers, working as part of the Manhattan Project, split uranium atoms contained within a large graphite pile—Chicago Pile-­1, the first nuclear reactor ever built.

Aecon-Wachs, the U.S. division of Aecon Nuclear, has been tapped to support the Department of Energy’s goal of repurposing the unfinished Mixed Oxide Fuel Fabrication Facility at the Savannah River Site (SRS) in South Carolina. Known as Building 226-F, the facility is being transitioned into the Savannah River Plutonium Processing Facility (SRPPF) to produce plutonium pits for the nation’s stockpile of nuclear weapons.

Advanced reactors and small modular reactors with strikingly different coolants and sizes offer an array of different benefits, but when it comes to fuel cycle issues, including spent fuel and waste, they have a lot in common with conventional light water reactors. Two reports released within the last week—a National Academies of Sciences, Engineering, and Medicine (NASEM) consensus committee report two years in the making and a Department of Energy study released by Argonne National Laboratory—address the timely topic of advanced reactor fuel cycle issues. While the NASEM committee ventured to define research and infrastructure needs to support the entire nuclear power fuel cycle, inclusive of new technologies, for decades to come, the DOE report compares the front- and back-end fuel cycle metrics of three reactor designs (from NuScale Power, TerraPower, and X-energy) that have been selected for DOE cost-share–funded demonstrations within this decade. Together, these reports provide assurance that the fuel cycle needs of a fleet of new reactors can be met and point to near-term research and planning needs.

The Biden-­Harris administration has committed to decarbonizing the power sector by 2035 and the economy by 2050, while creating good jobs and promoting equity. There’s no question that the lowest-­cost, most reliable grid of the future will require clean, firm baseload power to support intermittent renewable energy.

Nuclear is such a reliable source of firm, flexible baseload power for the grid. Energy mix optimization models show that as penetration of renewables (such as solar and wind) grows, required energy storage capacity also grows, leading to increasing cost competitiveness of dispatchable carbon-­free power sources (including low-­impact hydro, geothermal energy, carbon capture and storage, zero-­carbon fuels like hydrogen, and nuclear). Nuclear power is an essential component of America’s transition to a clean electric grid to maintain reliability, resiliency, and affordability.

Canadian Nuclear Laboratories (CNL) and General Fusion have announced a memorandum of understanding (MOU) to “develop fusion energy research capabilities within CNL, to support the goal of constructing a potential General Fusion commercial power plant in Canada before 2030.” The plant would follow on a demonstration-scale plant that General Fusion wants to have operating in the United Kingdom by 2027 to validate the performance and economics of the technology.

There are worse places to be than Vienna, Austria, in the early fall. The place has an old-world vibe for sure. The U-Bahn doesn’t have turnstiles; it runs on the honor system. People take care to dress up before they amble down the Kärntner Strasse, the city’s main shopping district.

Every September, a little further north, 3,000 delegates from around the world, along with 200 representatives from nongovernmental organizations, descend on the Vienna International Center of the United Nations—the VIC, for short—for the International Atomic Energy Agency’s General Conference. Attendees ply its curving hallways and attend side events, engage in meetings on the margins, and tour the national booth displays.

Inside the large, purpose-built plenary hall, a seemingly endless procession of national speakers, each allotted seven minutes (with flashing red digits to let all know who’s run over time), tout their nation’s achievements in nuclear technology and express its views on nuclear matters of any sort. As an accredited NGO, ANS has a desk in the plenary complete with microphone and wireless translation headset. An IAEA plenary is a highly scripted affair—one that looks boring at first glance, but once you put the headphones on and get acclimated to the vagaries of real-time translation, a coherent and interesting picture starts to emerge.

The Department of Energy announced a cost-shared award on November 10 valued at about $150 million for American Centrifuge Operating, a subsidiary of Centrus Energy, to complete the high-assay low-enriched uranium (HALEU) demonstration project it began in 2019. After delays that Centrus attributes in part to the COVID-19 pandemic, the company now has until the end of 2023 to produce the first 20 kilograms of HALEU enriched to 19.75 percent U-235 from the 16-centrifuge cascade it has installed in a DOE-owned Piketon, Ohio, facility—the only U.S. facility currently licensed to produce HALEU.

In the 1950s, the U.S. Department of Energy constructed the Portsmouth Gaseous Diffusion Plant in rural southern Ohio to enrich uranium, alongside two other federally owned and managed facilities in Oak Ridge, Tenn., and Paducah, Ky. The Cold War-era plant was built as a self-sufficient industrial city with more than 400 buildings and facilities centered around three massive gaseous diffusion process buildings that could enrich the level of the uranium-235 isotope for nuclear fuel in the defense and energy sectors.

Just days before COP27 and the U.S. midterm elections, the White House announced $1.55 billion in Inflation Reduction Act (IRA) funding for national laboratories and the launch of a Net-Zero Game Changers Initiative based on a new report, U.S. Innovation to Meet 2050 Climate Goals. Out of 37 research and development opportunities identified, fusion energy was selected as one of just five near-term priorities for the new cross-agency initiative. Together, the announcements signal policy and infrastructure support for fusion energy—the biggest chunk of Department of Energy Office of Science (DOE-SC) IRA funding went to ITER, via Oak Ridge National Laboratory—and for advanced nuclear technologies to power the grid and provide process heat to hard-to-decarbonize industrial sectors.

Rachel Taow, who is the process modernization lead for the Gateway for Accelerated Innovation in Nuclear (GAIN) at Idaho National Laboratory, received an award in the category of law and finance during the 11th Annual C3E Women in Clean Energy Symposium and Awards, held on November 2 in Washington, D.C. Taow has 16 years of government contracting experience—the last six spent with GAIN—and was nominated for the award by GAIN director Christine King.

The Clean Energy Education & Empowerment (C3E) Initiative was created in 2010 to close the gender gap in clean energy fields, and since 2012, outstanding mid-career women in clean energy have been recognized at the annual C3E symposium. Nine women received awards this year, including—for the first time in the 11 years of the C3E award program—a woman working to advance nuclear energy.

In May 2019, Zahn’s Corner Middle School in Pike County, Ohio, located within four miles of the former Portsmouth Gaseous Diffusion Plant (PORTS), was closed after local officials reported enriched uranium and transuranic radionuclides were detected inside the school and at outside air monitors.

Now, Cincinnati’s WKRC Local 12, a news affiliate of Sinclair Broadcast Group, is reporting that a private house in Lucasville, Ohio, 10 miles from the PORTS site, has been contaminated with enriched uranium.

Deploying a fleet of advanced reactors in the 2030s means deploying high-assay low- enriched uranium (HALEU) infrastructure now.

The future fleet will need more than 40 metric tons of HALEU by 2030, according to Department of Energy projections. Getting to the 5–20 percent fissile uranium-235 content of HALEU involves either enriching natural or low-enriched uranium (LEU) or downblending high-enriched uranium (HEU).

Because downblending the limited stocks of HEU held at the DOE’s Idaho National Laboratory and Savannah River Site is a short-term option at best, the Energy Act of 2020 authorized a HALEU Availability Program to build a sustainable enrichment infrastructure by the time advanced reactors are ready for commercial deployment.

Comments on a request for information reached the DOE in February 2022, just before Russia’s invasion of Ukraine amplified global energy security concerns. While the war in Ukraine didn’t change the DOE’s plans, it “accelerated everything,” said Kathryn Huff, who leads the DOE’s Office of Nuclear Energy (DOE-NE) as assistant secretary. “Our attention is now laser-focused on this issue in a way that it wouldn’t have been in the past.”

The nuclear industry leaders assembled in Washington, D.C., last week to discuss small modular reactor supply chains agreed that lost generation capacity from the expected retirement of hundreds or thousands of coal power plants over the next decade—a cliff, in one panelist’s words—represents an opportunity that developers of SMRs and advanced reactors are competing to meet.

“I think in total 80 projects are ongoing,” said Boris Schucht, panel moderator and chief executive officer of Urenco Group, as he opened the forum. “Of course not all of them will win, and we will discuss today what is needed so that they can be successful.”
