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.

The Nuclear Regulatory Commission sent a notice dated March 30 to Urenco USA regarding a proposed $70,000 civil penalty for two violations related to the improper implementation of safety controls at the company’s commercial enrichment facility in Eunice, N.M., which is operated by Louisiana Energy Services. The NRC publicly announced the proposed fine on April 3.

A new report from the environmental advocacy group RePlanet makes the case for recycling used nuclear fuel for use in advanced power reactors. According to the report, What a Waste: How fast-fission power can provide clean energy from nuclear waste, by using current inventories of used fuel and depleted uranium stocks in Europe and the United Kingdom, fast breeder reactors could generate between 600 and 1,000 years of carbon-free electricity for the entire European Union.

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.

The latest advances in nuclear fusion, the remaining challenges, and proposals to overcome those challenges are the focus of a new report, Fusion Energy: Potentially Transformative Technology Still Faces Fundamental Challenges, published by the Government Accountability Office.

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.

The first cask of used nuclear fuel was moved to dry storage at the Krško nuclear power plant in Slovenia on April 2, officially marking the storage facility’s commissioning, announced Holtec International, which is conducting the fuel transfer campaign.

According to Holtec, the current fuel loading campaign will consist of a total of 16 of the company’s HI-STORM FW casks being placed in dry storage.

The facility: Plant operator Nuklearna elektrarna Krško (NEK) received the operating license for the dry storage facility, the plant’s first, from the Slovenian Nuclear Safety Administration last October. The Krško facility was built under the management of Holtec’s Civil Design and Construction Department with the assistance of local supply chains, primarily consisting of Slovenian, Croatian, and Italian companies.

The Environmental Protection Agency has proposed adding the Fansteel Metals Superfund site in Muskogee, Okla., to the National Priorities List (NPL), the roster of the nation’s most contaminated sites that threaten human health or the environment. By adding this site to the NPL, the EPA said it can prioritize funding for cleanup and necessary enforcement action.

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.)

Representatives from the Japan Nuclear Damage Compensation and Decommissioning Facilitation Corporation (NDF) recently visited the Department of Energy's Office of Environmental Management (EM) headquarters in Washington, D.C., and the Hanford Site in Washington state to promote collaboration and provide updates on the status and plans to decommission Japan's Fukushima Daiichi nuclear power plant. The Great East Japan Earthquake of March 11, 2011, caused damage to the plant and surrounding communities. The NDF was created in September 2011 to oversee the decommissioning and cleanup of the plant, which is owned by the Tokyo Electric Power Company.
