Nuclear research reactors throughout the world enable crucial scientific progress that benefit many sectors, health care and the environment among them. But some of those reactors need an important adjustment: a conversion from using high-enriched uranium fuel to using low-enriched uranium fuel.
The Department of Energy’s Office of Science announced $112 million in funding on August 14 for 12 projects designed by fusion scientists, applied mathematicians, and computer scientists to apply high-performance computing and exascale computers to complex fusion energy problems.
The list of projects and more information can be found on the Fusion Energy Sciences homepage.
The Department of Energy today announced a noncompetitive financial assistance cooperative agreement with Southeast New Mexico College, located in Carlsbad, N.M., for educational programs to enhance the knowledge, skills, and abilities of current Waste Isolation Pilot Plant employees while also building and training WIPP’s next-generation workforce.
The Department of Energy’s Hanford Site has introduced its newest team members, Dee and Freda, two highly skilled explosive-detecting K-9 officers. The police dogs will work with Richland Operations Office contractor Hanford Mission Integration Solutions to help ensure the safety and security of the legacy nuclear reservation near Richland, Wash.
The Department of Energy announced last week that Melter 1 at the Hanford Site’s Waste Treatment and Immobilization Plant, also known as the Vit Plant, has hit its operational temperature of 2,100ºF. The DOE began heating Melter 1 in October 2022, but was soon forced to pause when abnormalities in the heaters’ power supply were encountered.
The Nuclear Waste Technical Review Board, which evaluates the Department of Energy’s activities on radioactive waste management, is holding a hybrid (in person and virtual) public meeting on August 30 to discuss the DOE’s consent-based process for siting one or more federal interim storage facilities for commercial spent nuclear fuel. The DOE’s research and development related to high-burnup SNF and advanced reactor waste disposal will also be discussed.
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.
The Department of Energy is providing $4.6 million in funding for 18 projects at national laboratories and U.S. universities to help address critical scientific and technological challenges in pursuing fusion energy systems.
The Department of Energy is planning to ship contaminated process equipment from its Savannah River Site in South Carolina to Waste Control Specialists’ federal low-level radioactive waste facility in Andrews County, Texas.
The Department of Energy is holding an initial Industry Day on July 28 that is open to parties with proven experience in implementing successful clean electricity projects generating 200 MW or larger.
The Spallation Neutron Source (SNS) at the Department of Energy's Oak Ridge National Laboratory set a world record when its particle accelerator beam operating power reached 1.7 MW, an improvement on the facility’s original design capability of 1.4 MW, ORNL announced on July 21. That higher power provides more neutrons for researchers who use the Office of Science user facility for materials science investigations.

The Department of Energy’s Carlsbad Field Office announced that it has made a significant step toward increasing airflow to the Waste Isolation Pilot Plant (WIPP) underground with the excavation of a new utility shaft. According to the office, crews working on the shaft recently reached an underground depth, known as station depth, that will allow horizontal tunneling work to begin on connecting the shaft to the WIPP repository complex.
Located in southeastern New Mexico, the repository for defense-related transuranic waste sits 2,150 feet below ground level. Airflow to the underground has been restricted following a radiological release in 2014.
When completed, the 26-foot-diameter utility shaft will provide air to WIPP’s new ventilation system, called the Safety Significant Confinement Ventilation System (SSCVS). The increased airflow provided by the system will allow for simultaneous mining, rock bolting, waste emplacement, and maintenance operations.
Commonwealth Fusion Systems (CFS) and Tokamak Energy Inc. are the two magnetic confinement tokamak fusion developers to receive a portion of the $46 million in funding announced by the Department of Energy in late May for the first 18 months of a public-private Milestone-Based Fusion Development Program aimed at developing fusion pilot plant designs and resolving related scientific and technological challenges within five to 10 years.
“It is critical after the Hamaoka Nuclear Power Station restart that we reduce our cost and increase our capacity factor while becoming more economically competitive.” Ichiro Ihara, chief nuclear officer of Chubu Electric Power, made this observation recently when the Electric Power Research Institute visited the Japanese nuclear power plant for a strategy development session for plant modernization. EPRI’s team of five specialists spent four days at Hamaoka to investigate the feasibility of potential improvements—the third step of the EPRI modernization strategy planning process. It was a trip six months in the making—and the first time EPRI has applied its nuclear plant modernization process outside the United States.
Take note! Registration closes today for the U.S. Department of Energy Conference for Newcomers: Understanding Exports of Advanced Reactor Technologies, scheduled for July 26–27 at Argonne National Laboratory in Lemont, Ill.
Contact Mercedes Trent (mercedes.trent@nnsa.doe.gov) to sign up for the conference. Additional information will follow upon registration.
Princeton Stellarators Inc. (PSI) and Type One Energy Group are two of the eight fusion developers selected by the Department of Energy in late May to receive a total of $46 million in funding to kick off a public-private Milestone-Based Fusion Development Program aimed at developing fusion pilot plant designs and resolving related scientific and technological challenges within five to 10 years. The DOE’s selections cover an array of plasma confinement concepts, including the magnetic confinement stellarators being developed by PSI and Type One more than 70 years after the stellarator was first envisioned.
Nuclear Newswire previously took a close look at two of the DOE’s picks: Realta Fusion and Zap Energy (“innovative concept”) and Focused Energy and Xcimer Energy (inertial fusion). Here, we’ll examine how PSI and Type One are engineering solutions to the fusion plasma confinement challenge. Both companies are benefiting from recent advances in computing power and high-temperature superconducting (HTS) magnets. It’s in plans for design, manufacturing, assembly, and control of their stellarators that they differ.
The Gateway for Accelerated Innovation in Nuclear (GAIN) announced June 26 the companies that have received GAIN Nuclear Energy Vouchers, which allow private companies to access the expertise and research capabilities of Department of Energy national laboratories to advance their projects toward commercial deployment. This is the third round of GAIN vouchers awarded for fiscal year 2023; the first round was announced in December 2022 and the second in March.
The future of nuclear power and nuclear science will be informed by the past. But how did “the future” look six decades ago? We’ll check back on the predictions of ANS members in 1965 before assessing the investments in technology, workforce, and licensing needed now.
Like many researchers, I long ago recognized the significance of debates about open access (OA) publishing. However, I did not become too deeply involved, knowing that I alone could not directly influence any outcomes.
The first was the memo from the White House Office of Science and Technology Policy (OSTP)—commonly referred to as the Nelson memo—issued in August last year. In it, grant recipients are guided to provide immediate public access to research papers and data resulting from federally funded research. The second was my election as president of the American Nuclear Society. During my term from June 16, 2022, through June 15, 2023, I faced very concrete decisions that led to the recent launch of ANS's latest publishing venture, Nuclear Science and Technology Open Research (NSTOR).
