Big news as I write this, my last column as ANS president: Legislation has been passed that will ban the importation of uranium from Russia (though waivers can be used in certain circumstances to continue imports through 2027). This ban has been discussed since the Russian invasion of Ukraine. I am sure all U.S. utilities have followed their risk-management policies.

With two years to plan, appropriate-use waivers, and access to American Assured Fuel Supply, there should not be any disruption to domestic reactor operations. The ban will force the United States and our Western allies to be independent and stronger. Congress has helped by providing $2.72 billion to support new domestic enrichment capacity. The challenge now is for the Department of Energy to turn this into actual new capacity as quickly as possible.

During the 2024 International Conference on Nuclear Security (ICONS) in May, representatives from the U.S. Department of Energy and the National Nuclear Security Administration discussed U.S. nuclear security priorities, noted their achievements and those of U.S. partners, and explained how to tackle the security challenges of today and tomorrow.

The large vehicle used to transport highly radioactive canisters at the Department of Energy’s Savannah River Site has completed a pit stop to ensure the continued movement of the site’s radioactive liquid waste work.

Utilities need to know months ahead of a scheduled refueling outage that fresh fuel will be on-site and ready to load. Now that the Prohibiting Russian Uranium Imports Act has been signed into law, U.S. utilities with plans to use Russian-origin low-enriched uranium also need to know if they can secure a waiver for imports through December 31, 2027—subject to specific annual limits—if “no alternative viable source of [LEU] is available to sustain the continued operation of a nuclear reactor or a United States nuclear energy company” or if LEU imports from Russia are “in the national interest.”

The Defense Nuclear Facilities Safety Board (DNFSB), an independent government organization responsible for overseeing public health and safety issues at Department of Energy defense nuclear facilities, has alerted the DOE because of safety concerns it has regarding the use of continuous air monitors (CAM) at the Waste Isolation Pilot Plant in New Mexico.

Part of WIPP’s new Safety Significant Confinement Ventilation System (SSCVS), the CAM system is intended to detect a radiological release in the repository and automatically close vent dampers to prevent the escape of radioactive particles to the outside environment. The SSCVS, which began commissioning in November 2023, is intended to increase airflow to the underground to allow for simultaneous underground waste emplacement, mining, and ground control work.

There is a mix of good news and bad in the latest Nuclear Engineering Enrollment and Degrees Survey, 2021–2022 Data. According to this report from the Oak Ridge Institute for Science and Education (ORISE), compiled with data initially released in November 2023 and updated in February 2024, the number of doctoral degrees awarded in nuclear engineering at the end of the 2022 academic year in the United States—211 Ph.D.s—was the highest since the beginning of this survey’s data collection in 1966. However, the overall numbers of nuclear engineering degrees awarded in 2021 and 2022 were at their lowest levels in more than a decade. In addition, both undergraduate and graduate enrollment numbers were down compared with 2018 and 2019.

The DIII-D National Fusion Facility is starting up after an eight-month experimental hiatus, equipped with new and improved plasma control and diagnostic systems. The upgrades will help researchers from around the nation and the world resolve key physics questions to bridge the gap between current magnetic confinement fusion research and the first fusion power pilot plants. General Atomics, which operates DIII-D for the Department of Energy, announced the completion of upgrades on May 8.

The Department of Energy’s Isotope Program (DOE IP) announced last week that it would end its “active standby” capability for strontium-82 production about two decades after beginning production of the isotope for cardiac diagnostic imaging. The DOE IP is celebrating commercialization of the Sr-82 supply chain as “a success story for both industry and the DOE IP.” Now that the Sr-82 market is commercially viable, the DOE IP and its National Isotope Development Center can “reassign those dedicated radioisotope production capacities to other mission needs”—including Sr-89.

The U.S. Department of Energy, Washington State Department of Ecology, and U.S. Environmental Protection Agency have reached an agreement on revised plans for managing millions of gallons of radioactive and chemical liquid waste stored in 177 underground tanks at the Hanford Site near Richland, Wash.

The United States has an ambitious goal: to establish a high-assay low enriched-uranium advanced nuclear fuel supply chain, revive the once thriving nuclear fuel market for low-enriched uranium in the nation, and “reestablish U.S. leadership in nuclear energy more broadly.” Making a success of that could have impacts beyond the nuclear sector. According to the Department of Energy’s Office of Nuclear Energy, “Expanding domestic LEU and HALEU enrichment production will be essential for fueling the clean energy required to bring down emissions in all sectors of the economy—including in hard-to-abate sectors such as manufacturing and industrial—while delivering high paying jobs to communities across the country.”

The Department of Energy has issued a request for qualifications (RFQ) for interested parties that are looking to establish carbon pollution–free electricity (CFE) projects at its Waste Isolation Pilot Plant site in New Mexico.

The Department of Energy’s Office of Environmental Management has authorized the newest megavolume disposal unit to begin operating at the Savannah River Site in South Carolina.

The mission of the Department of Energy’s Office of River Protection (ORP) is to complete the safe cleanup of waste resulting from decades of nuclear weapons development. One of the most technologically challenging responsibilities is the safe disposition of approximately 56 million gallons of radioactive waste historically stored in 177 tanks at the Hanford Site in Washington state.

ORP has a clear incentive to reduce the overall mission duration and cost. One pathway is to develop and deploy innovative technical solutions that can advance baseline flow sheets toward higher efficiency operations while reducing identified risks without compromising safety. Vitrification is the baseline process that will convert both high-level and low-level radioactive waste at Hanford into a stable glass waste form for long-term storage and disposal.

Although vitrification is a mature technology, there are key areas where technology can further reduce operational risks, advance baseline processes to maximize waste throughput, and provide the underpinning to enhance operational flexibility; all steps in reducing mission duration and cost.

The Department of Energy’s Office of Environmental Management has issued a request for qualifications for interested parties and prospective offerors looking to enter into a realty agreement for carbon-pollution-free electricity (CFE) projects at the department’s Waste Isolation Pilot Plant site in southeastern New Mexico.

The Office of Nuclear Energy is awarding $59.7 million to 25 U.S. colleges and universities, two national laboratories, and one industry organization to support nuclear energy research and development and provide access to world-class research facilities, the Department of Energy announced on April 15.

Huff

After serving two years as the Department of Energy’s assistant secretary for Nuclear Energy, Kathryn Huff will vacate that position on May 3 and return to teaching. Huff had started at the DOE in May 2021, serving for one year as the principal deputy assistant secretary for Nuclear Energy.

“Serving in this capacity has been an unparalleled privilege, and I’m immensely grateful for the opportunity to have worked alongside you--the dedicated and talented public servants in Nuclear Energy, in DOE, and across the Biden-Harris Administration,” Huff wrote in an email announcement to colleagues last week. “I chose this timing to enable the smoothest transition back to my professorship at the University of Illinois at Urbana-Champaign where my beloved research, students, husband, and dog await.”

Nuclear Regulatory Commission staff will host a public information meeting on Wednesday, April 17, to discuss plans for repowering the shuttered Palisades nuclear plant in Michigan.

Researchers at the Department of Energy’s Argonne National Laboratory are developing and deploying ARG-US (from the Greek Argus, meaning “Watchful Guardian”) remote monitoring systems technologies to enhance the safety, security, and safeguards (3S) of packages of nuclear and other radioactive material during storage, transportation, and disposal.

Last year in late August, 120 storage cylinders of depleted uranium oxide (DUOx) safely arrived by rail in West Texas, having been shipped from the Department of Energy’s Portsmouth Site in Ohio. It was the first such shipment of the stable crystalline powder from the Portsmouth Site and was another milestone in the DOE Office of Environmental Management’s (EM) efforts to ship DUOx for off-site disposal.
