Earlier this year, Nuclear Waste Services, the radioactive waste management subsidiary of the U.K. Nuclear Decommissioning Authority, hosted a group of five teenagers for a week of exposure to real-world work environments at its facilities in Calderbridge, Cumbria. The students learned about career opportunities and leadership responsibilities at the company while they engaged with senior management and performed activities with several NWS teams, including employees in the environmental, waste characterization, cybersecurity, human resources, and geological disposal facility grants departments.

Last week saw a wave of U.S. and U.K. nuclear companies and organizations forging new transatlantic ties, with even the American Nuclear Society and the U.K.’s Nuclear Institute reaching a new agreement.

With President Trump on a state visit to the U.K., in part to sign a landmark new agreement on U.S.-U.K. nuclear collaboration, a flurry of transatlantic partnerships and deals bridging the countries’ nuclear sectors have been announced.

The American Nuclear Society is taking an active role in this bridge-building by forming a reciprocal membership agreement with the U.K.’s Nuclear Institute.

The U.K.’s Sellafield Ltd. and Japan’s Tokyo Electric Power Company have pledge to continue to work together for up to an additional 10 years, extending a cooperative agreement begun in 2014 following the 2011 tsunami that resulted in the irreparable damage of TEPCO’s Fukushima Daiichi plant.

As the U.K. government looks to finalize investment decisions for the construction of the Sizewell C nuclear power plant this summer, France’s state-owned EDF has announced plans to take a 12.5 percent stake in the project and commit up to £1.1 billion ($1.5 billion) in funding.

U.S.-based private capital group Apollo Global has committed £4.5 billion ($6.13 billion) in financing to EDF Energy, primarily to support the U.K.’s Hinkley Point C station. The move addresses funding needs left unmet since China General Nuclear Power Corporation—which originally planned to pay for one-third of the project—exited in 2023 amid U.K. government efforts to reduce Chinese involvement.

It’s a move that “brings to an end decades of dithering and delay, with the government backing the builders.” That’s how the U.K. government announced, with alliterative fanfare, its £14.2 billion (about $19.2 billion) investment in Sizewell C, where EDF Energy plans to build two 1,600-MWe EPRs.

Rolls-Royce SMR has emerged as the United Kingdom’s preferred bidder to build the country’s first small modular reactors following a two-year competition, the U.K. government announced June 10. Rolls-Royce SMR expects to build three SMRs with Great British Energy–Nuclear, subject to contracting later this year and regulatory approvals. Great British Energy–Nuclear will “aim to allocate a site later this year and connect projects to the grid in the mid-2030s.”

The community of Lincolnshire in eastern England voted on June 3 to withdraw from consideration to host a deep geologic repository for high-level radioactive waste. Lincolnshire was one of three communities the U.K. government’s Nuclear Waste Services identified in January as possible hosts for a repository.

A 1960s Electrolux vacuum cleaner was among the more unusual items workers removed from one of the world’s oldest nuclear waste stores at the United Kingdom’s Sellafield nuclear site.

Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.

TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Shaping the global nuclear future requires an understanding of nuclear’s role in addressing national and energy security endeavors together with foresight into the energy sector’s future needs. Nuclear typically produces reliable baseload electricity, but it could also play an important role in economically viable cogeneration. In addition, future electricity demand will require significant enhancements to baseload generation. Addressing these challenges requires a combination of innovation, collaboration, capacity enhancements, and focused strategic investments.

Nuclear is increasingly recognized as essential to enabling energy security and achieving net-zero emissions. The United Kingdom has demonstrated leadership in this area, with initiatives such as the Young Generation Network’s global #NetZeroNeedsNuclear campaign at COP26 in Glasgow, Scotland. Efforts like these are impossible without international collaboration.

Sellafield Ltd. and AtkinsRéalis have successfully operated a robotic dog from a remote location in what might be the first time such an operation has happened at a nuclear licensed site, according to the companies in a March 18 press release.

The U.K. government’s Nuclear Waste Services said it has identified three “areas of focus” in its search to find a suitable site and a willing community to host a geologic disposal facility (GDF) for the country’s most hazardous radioactive waste. The areas are within three communities currently involved in the siting process—Mid Copeland and South Copeland in Cumbria, and East Lincolnshire, England.

Tokamak Energy’s ST40 experimental fusion facility will receive a $52 million upgrade under a joint public-private effort with the U.S. Department of Energy and the U.K. Department of Energy Security and Net Zero (DESNZ) aimed at advancing the fusion science and technology needed to deliver a future pilot plant.

Leadership of the United Kingdom’s STEP (Spherical Tokamak for Energy Production) fusion program has transitioned to U.K. Industrial Fusion Solutions Ltd. (UKIFS), a wholly owned subsidiary of the U.K. Atomic Energy Authority (UKAEA). UKIFS was established in February 2023 to lead a public-private partnership that will design, build, and operate the STEP prototype fusion energy plant in Nottinghamshire in England’s East Midlands region.

Despite progress made over the past years, the United Kingdom’s Nuclear Decommissioning Authority (NDA) has not seen an adequate return on investment in cleaning up the Sellafield nuclear site on England’s Cumbria coast, according to a new report by the U.K.’s National Audit Office, which scrutinizes government spending.

The Nuclear Decommissioning Authority (NDA), the government agency charged with cleaning up the United Kingdom’s nuclear sites, has awarded three contracts totaling £30 million (about $39 million) for research into new decommissioning techniques.

A plan to build up a high-assay low-enriched uranium fuel cycle in the United Kingdom to support the deployment of advanced reactors is still in place after the Labour party was voted to power on July 4, bringing 14 years of conservative government to an end. A competitive solicitation for grant funding to build a commercial-scale HALEU deconversion facility opened days before the election, and the support of the new government was confirmed by a set of updates on July 19. But what does the U.K. HALEU program entail, and how does it differ from the U.S. HALEU Availability Program?

Japan’s recent moves to boost fusion power in the nation’s energy plan and accelerate the timeline for a prototype fusion power plant come in response to increased global attention on fusion energy. Even as ITER faces delays, more than 40 private fusion developers are pursuing different technologies and competing for attention. And so are other countries, including the United Kingdom, which announced its plans for a fusion pilot plant back in 2019. Fusion companies and nations alike are responding to a growing sense that there is a race—or at least collective momentum—to commercialize fusion energy.
