The Department of Energy’s Office of Environmental Management awarded a 10-year contract worth up to $45 billion to Hanford Tank Waste Operations and Closure (H2C) of Lynchburg, Va., to oversee the management of liquid radioactive tank waste at the DOE’s Hanford Site in southeastern Washington state.

World Quantum Day: It’s here, there, and everywhere

April 14, 2023, 6:57AMNuclear News

The organizers of World Quantum Day, celebrated annually on April 14, want to shift how people think about quantum physics. What can seem like a bafflingly abstract theory tinged with science fiction is actually a fundamental description of reality, the basis of technologies we use every day, and a foundation for future applied science. Whether it’s seen through the lens of fact or fiction, quantum physics has an undeniable “cool” factor, and quantum scientists working in different fields—including fusion energy—are embracing quantum coolness to spread awareness about real science.

The earliest DT nuclear fusion discoveries

Fusion energy research has seen exciting recent breakthroughs. The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory has achieved ignition,1,2 and in the United Kingdom, the Culham Centre for Fusion Energy’s Joint European Torus (JET) has produced a record 59 megajoules of fusion energy.3 Against this backdrop of advances, we provide an account of the earliest fusion discoveries from the 1930s to the 1950s.* Some of this technical history has not been previously appreciated—most notably the first 1938 reporting of deuterium-tritium (DT) 14-MeV neutrons at the University of Michigan by Arthur Ruhlig.4 This experiment had a critical role in inspiring early thermonuclear fusion research directions. This article presents some unique insights from the extensive holdings within Los Alamos National Laboratory’s archives—including sources typically unavailable to a broad audience.

Underwater Construction Corporation (UCC) UK Ltd. announced that it has recently completed a nuclear diving pilot project at the Pile Fuel Storage Pond (PFSP) at the Sellafield nuclear site in Cumbria, England. UCC UK said the project marks a significant decommissioning milestone for Sellafield, demonstrating the capability of the company’s methods and equipment to remediate the legacy nuclear pond while limiting worker dose.

The oldest pool on the Sellafield site, the PFSP was constructed between the late 1940s and early 1950s as a storage and cooling facility for irradiated fuel and isotopes from the two Windscale reactors and was in full operation until 1962. Then through the mid-1970s, the pond facility, one of six on the site, was used for storage of intermediate-level waste and fuel from the U.K. nuclear program.

BWX Technologies announced on April 10 that its Nuclear Fuel Services subsidiary in Erwin, Tenn., has been awarded a five-year, $428 million contract from the National Nuclear Security Administration to purify and convert high-enriched uranium (HEU) from an oxide to a metal. The Phase II contract follows the successful completion by NFS of a $57.5 million contract awarded two years ago for a process line design and pilot demonstration.

NARUC, NASEO launch program for new nuclear deployment

April 13, 2023, 7:01AMNuclear News

The National Association of Regulatory Utility Commissioners (NARUC) and National Association of State Energy Officials (NASEO) have announced the launch of the Advanced Nuclear State Collaborative (ANSC)—an effort to bring together utility regulators and energy officials from across the nation to “enhance collective understanding” of the regulatory and policy issues facing states contemplating the deployment of new nuclear generation.

More than a decade after construction was declared completed, Idaho’s long-delayed Integrated Waste Treatment Unit (IWTU) has begun radiological operations, the Department of Energy’s Office of Environmental Management (EM) announced.

On Tuesday, crews at the Idaho National Laboratory Site began sending radioactive sodium-bearing liquid waste from nearby underground tanks to the IWTU for treatment. The 900,000 gallons of waste was generated during decontamination activities following spent nuclear fuel reprocessing that ended in 1992.

The IWTU uses steam reforming fluidized-bed reactor technology to convert liquid waste to a granular solid resembling coarse sand more suitable for long-term disposal.

Nuclear science and technology in space

Anyone who has heard me speak about the American Nuclear Society recently knows that I like to remind people of the ANS mission and vision statements. I invite people to read the exact words: Our mission is to “advance, foster, and spur the development and application of nuclear science, engineering, and technology to benefit society”; our vision is to see “nuclear technology . . . embraced for its vital contributions to improving peoples’ lives and preserving our planet.”

The meaning behind these statements is that ANS is here to help the profession save the world. I take that seriously: We are here to save the world. This month, Nuclear News is focusing on nuclear science, engineering, and technology’s role in space exploration both now and in the future. When we look at our mission, this is very fitting. The use of nuclear power systems in space goes back almost to the start of ANS. In 1961, the Transit 4A satellite became the first U.S. spacecraft to be powered by a radioisotope thermoelectric generator (RTG). Combined with solar cells, RTGs have been used on the Moon and on satellites and to explore the solar system and beyond. One of the interesting things about these power sources is that they were used to provide both provide electricity and heat to keep the systems they were supporting from freezing. Since then, additional nuclear systems have been designed and developed—including fission power reactors and nuclear thermal propulsion—that will provide significantly more power and faster space journeys.

At the advent of space nuclear power in the 1960s, the combination of fundamental nuclear principles and first-of-its-kind spacecraft technology were the largest barriers to entry. In the modern era, however, nuclear power production and space technology have matured industries and no longer present major challenges. These days, the biggest hurdles are advanced flexible technology development, regulations and policy, and public perception, and these issues must be successfully navigated to clear the way for a nuclear future in space.
