The United Kingdom’s Royal Navy is considering the integration of nuclear power into its fleet of surface ships. The Ministry of Defense has issued a Request for Information (RFI) to gather insights from the defense industry on incorporating Generation 4 nuclear reactors into its existing fleet.
The RFI seeks to explore the feasibility and benefits of adding advanced nuclear technologies to Royal Navy surface ships. The MOD is requesting detailed information on Generation 4 nuclear reactor designs, their application to large surface vessels, and the potential challenges associated with their use. The submission deadline for responses is October 9, 2024.
According to the contract summary, the Royal Navy is interested in understanding how Generation 4 nuclear reactors, including both larger reactors and micromodular reactors, could be integrated into its surface fleet. These reactors represent the latest advancements in nuclear technology, offering improvements in affordability, safety, and efficiency compared to current reactor technologies.
The RFI aims to align the MOD with industry capabilities and processes, facilitating informed strategic decisions and potential investments. Once submitted, responses will be reviewed by experts from various functional areas within the Navy Command Headquarters and other relevant MOD departments.
Nuclear power has long been associated with submarines due to their need for extended periods at sea without refueling. Currently, over 160 ships worldwide use small nuclear reactors, primarily for long-range capabilities and powerful propulsion. Countries like the US, Russia, and China already operate nuclear-powered warships.
The Royal Navy’s existing nuclear capabilities are centered around the Vanguard Class of ballistic missile submarines, which use Rolls-Royce PWR 2 reactors for propulsion and electricity. However, the Navy’s ambitions extend to its surface fleet, which includes the HMS Queen Elizabeth and HMS Prince of Wales—some of the largest warships ever built.
Incorporating nuclear reactors into these ships could significantly enhance their operational range and speed while promoting more sustainable, emission-free operations. The Royal Navy’s exploration into nuclear power underscores its commitment to advancing maritime technology and maintaining strategic superiority.
