As the digital age propels forward with advancements in artificial intelligence (AI), data centres face an unprecedented demand for energy. Traditional energy sources are increasingly seen as unsustainable, leading to a heightened interest in advanced nuclear power. This interest was highlighted during a recent presentation at Foresight NetZero by Steven Coates from X-Energy, a company at the forefront of developing small modular reactors (SMRs) and innovative nuclear fuel solutions.
X-energy and Its Advanced Nuclear Solutions
X-energy specialises in Advanced Small Modular Reactors (SMRs) and is a key player in nuclear fuel manufacturing. Based in Rockville, Maryland, with a significant presence in the UK, the company aims to support global energy security and net-zero ambitions. Their flagship XC-100 reactor is a high-temperature gas reactor, helium-cooled and graphite-moderated, capable of producing 320 megawatts of thermal power and 80 megawatts of electrical power. This modular approach reduces construction time and costs compared to traditional nuclear reactors.
Nuclear Power for AI and Data Centres
One of the most compelling applications for advanced nuclear power is in supporting data centres, which are integral to the development and operation of AI. Data centres require consistent and scalable energy sources to manage the vast computational demands. The XC-100 reactors can adjust their output to match varying loads, a feature known as load following, which is particularly beneficial for data centres. This ability to scale energy production from 100% to 40% and back within 60 minutes ensures that energy supply meets the fluctuating demands efficiently.
Broader Applications of Nuclear Power
Beyond powering data centres, X-energy's reactors offer multiple applications:
Electricity Generation: The reactors can provide electricity directly to the grid or via direct wire to specific facilities, ensuring a reliable power supply.
Steam Off-Take: High-quality steam produced by the reactors can be used for industrial processes, including hydrogen production and sustainable fuel generation.
District Heating: The reactors' ability to produce consistent heat makes them suitable for district heating solutions, reducing reliance on fossil fuels.
Process Heat: Various industries can use the high-temperature steam for processes requiring substantial heat energy.
Regulatory and Construction Advantages
X-energy's approach to nuclear power also addresses common concerns about nuclear energy's feasibility and safety. The intrinsic safety of their reactor fuel, which is encased in carbon and ceramic, significantly reduces the risk of accidents. Furthermore, the smaller size and modular nature of their reactors mean shorter construction times and lower costs. For instance, their first project with Dow Chemicals in Texas is expected to be operational by 2030, following a four-year construction period starting in 2026.
Economic and Environmental Impact
Deploying a fleet of XC-100 reactors in the UK could generate substantial economic benefits, estimated at over £20 billion, and support high local content through the supply chain. Moreover, the reactors' operation can significantly reduce carbon emissions, contributing to national and global decarbonisation goals. X-energy's ambition includes building 40 XC-100 reactors in the UK, providing 3.2 gigawatts of electrical power and 8 gigawatts of thermal power.
Strategic Partnerships and Future Prospects
X-energy has established strategic partnerships with key UK entities, including Cavendish Nuclear and Teesside University, to support their deployment plans. These collaborations aim to enhance the UK's manufacturing supply chain, construction feasibility, and spent fuel management. The government's recognition of X-energy's advanced nuclear technology through funding awards underscores the potential and importance of their solutions in achieving net-zero targets.
Conclusion
As the demand for AI and data centre operations grows, advanced nuclear power presents a viable, sustainable energy solution. X-energy's innovative SMR technology not only meets the energy demands of data centres but also offers versatile applications across various industries. With strategic partnerships and a commitment to safety and efficiency, advanced nuclear power is poised to play a crucial role in the future of energy.
