Diverse SMR Designs Vie for UK’s Attention
The UK’s ambition to expand its nuclear energy capacity to 24 GW by 2050 includes a mix of traditional large-scale plants and Small Modular Reactors (SMRs).
While GE Hitachi, Holtec, NuScale Power, Rolls-Royce SMR, and Westinghouse have submitted their SMR designs, EDF has withdrawn its Nuward model from the Great British Nuclear (GBN) selection process.
EDF’s Withdrawal: A Strategic Decision
EDF cited “incompatibility” between the GBN’s required commitment level and timeline, and the current maturity of the Nuward SMR, as the reason for its withdrawal. This follows EDF’s recent announcement to optimize the Nuward design using proven technologies to meet project deadlines and budgets.
Competing SMR Technologies in the Spotlight
GE Hitachi has submitted its BWRX-300 SMR, emphasizing its proven track record, licensed fuel, and manufacturing-ready design. They view the BWRX-300 as the “lowest risk and highest reward choice” for GBN.
Rolls-Royce SMR also submitted its tender, expressing confidence in its rapid progress towards the next phase. They believe their SMR offers significant export potential for countries seeking long-term, low-carbon energy solutions.
Holtec’s submission highlighted their collaboration with Hyundai Engineering & Construction and the strategic cooperation between the US, UK, and South Korea. They see their SMR-300 as crucial for UK energy security.
NuScale submitted a tender for its VOYGR SMR, emphasizing its readiness for deployment with completed R&D, regulatory approvals, and manufacturing underway.
Westinghouse, with its AP300 SMR, has applied for Generic Design Assessment, highlighting its proven technology and established supply chain. They express confidence in their ability to meet the UK’s energy security and net-zero goals.
Future Outlook and Government Influence
The initial timeline aimed to shortlist four SMR designs and award contracts to two or three providers by the end of the year. The goal was to co-fund the technology through the design and regulatory process, potentially leading to equipment supply contracts.
The impact of the recent change in government on the selection process remains unclear. However, the incoming Labour government has expressed support for nuclear energy and aims to bolster the sector’s long-term security.
In conclusion, while EDF’s withdrawal alters the landscape, the UK’s SMR competition continues, with a diverse range of technologies vying for a role in the nation’s future energy mix. The path forward remains dynamic, shaped by both technological advancements and political decisions.
