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.

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.

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.

The Defense Nuclear Facilities Safety Board (DNFSB) is scheduled to visit the Department of Energy’s Savannah River Site in South Carolina the week of May 8 to discuss ongoing safety concerns and the protection of the public and workforce, as well as the DOE’s effectiveness in addressing those concerns.

The Department of Energy’s National Nuclear Security Administration has awarded nine new grants totaling $40.8 million to minority-serving institutions (MSIs) to promote the development of a diverse, highly skilled, and enduring stream of students in STEM fields who may find careers with the NNSA. Each grant that was awarded has a three- to five-year period of performance.

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.

As part of the run-up to the G7 Ministers’ Meeting on Climate, Energy, and Environment in Japan on April 15–16, U.K. energy security secretary Grant Shapps met in Seoul yesterday with South Korean trade, industry, and energy minister Chang-yang Lee to discuss closer collaboration on clean energy development and energy security.

The Department of Energy’s National Nuclear Security Administration has announced the establishment of the Advisory Committee for Nuclear Security (ACNS). Formerly known as the Defense Programs Advisory Committee, the newly formed ACNS is enlisting experts with knowledge of NNSA missions to provide independent advice and recommendations to the agency’s leadership.

The Department of Energy last week announced up to $450 million in funding from the Bipartisan Infrastructure Law to advance clean energy demonstration projects at current and former mine sites. The law, officially the Infrastructure Investment and Jobs Act, was signed by President Biden in November 2021.

Canadian firms Cameco and Bruce Power have announced a 10-year extension of their long-term exclusive nuclear fuel supply arrangements, securing power generation from the eight-unit 6,507-MWe Bruce nuclear plant through 2040.

In this article, we will explore prior NASA programs that incorporated fission technology for space exploration purposes. We also will look at current programs that incorporate fission technology for deep space missions, including missions to the Moon and Mars.

With the release last week of the policy paper Powering Up Britain, the U.K. government unveiled its plan to enhance the nation’s energy security and deliver on its ambitious net-zero commitments.

“This document explains how we will diversify, decarbonize, and domesticate energy production by investing in renewables and nuclear, to power Britain from Britain,” writes U.K. secretary of state for energy security and net zero Grant Shapps in the foreword. “It sets out the extraordinary opportunities opening up in technologies like carbon capture, usage, and storage; floating offshore wind manufacturing; and hydrogen, which will not only help us reach net zero but also consolidate Britain’s position as a global leader in green energy. And it details how we will use that leadership to influence energy decarbonization internationally.”

Portland, Ore.–based PacifiCorp—owner of the soon-to-be-retired Wyoming coal plant selected in 2021 as the future site of TerraPower’s Natrium reactor demonstration project—has released its 2023 Integrated Resource Plan, which recommends the addition of two more Natrium units to the company’s generation resource mix by 2033.

At the University of Rhode Island, I initially enrolled as a candidate for an accelerated track to earn bachelor’s and master’s degrees in mechanical engineering, with a minor in nuclear engineering. My objective was to concentrate on reactor power design and join efforts to make nuclear energy safer, more efficient, and less stigmatized.

My plans changed after I attended a guest presentation on high-performance nuclear thermal propulsion (HP-NTP) led by Michael Houts, manager of NASA Nuclear Research at Marshall Space Flight Center. He posted his email address on one of the last slides, so I took a chance and contacted him about potential research opportunities and thesis work. As it turned out, that one little email ultimately led to four NASA-sponsored design projects at URI—two are complete, and two are in progress—as well as my thesis. My research has been on HP-NTP, specifically the centrifugal nuclear thermal rocket (CNTR) design. In that design, liquid uranium is heated to extremely high temperatures in a cylinder that is rotated between 5,000 and 7,000 revolutions per minute as liquid hydrogen passes through the center of the cylinder, where it is heated and expanded, exiting as a propellant while the liquid uranium is retained by centrifugal force.

The United Kingdom’s nuclear regulators—the Office for Nuclear Regulation (ONR), the Environment Agency, and Natural Resources Wales (NRW)—have announced the completion of step one of their generic design assessment (GDA) for Rolls-Royce SMR’s 470-MWe small modular reactor design and the start of step two, which is expected to last 16 months.

Canada’s Bruce Power, operator of Ontario’s eight-unit Bruce nuclear power plant, has announced the issuance of C$600 million (about $446.3 million) in green bonds in support of the company’s net-zero-by-2027 goal. (Investopedia defines green bonds as fixed-income instruments specifically earmarked to raise money for environmentally friendly projects.)

The Department of Energy reported on March 30 that the Savannah River Site’s H Canyon facility recently initiated actions to recycle a small amount of used high-enriched uranium (HEU). SRS is a 310-square-mile DOE site in South Carolina.

The HEU, which is currently stored at the site’s H Area, will be downblended in a few years into high-assay low-enriched uranium (HALEU), which will help to provide fuel for advanced nuclear reactors in the United States.

The DOE has a brief video available with graphic information about HALEU.

Unit 3 at the Vogtle nuclear power plant has been successfully synchronized and connected to the electric grid, Georgia Power announced on April 1. The unit—one of two Westinghouse-supplied AP1000s at the Waynesboro, Ga., plant’s nuclear expansion site—becomes the first new U.S. power reactor to start up in seven years.
