The UK is making strides in sustainable decommissioning practices by embarking on the dismantling of a nuclear-powered submarine, Swiftsure, using a groundbreaking methodology that aims to recycle or reuse 90 percent of the vessel. This innovative approach is being managed by Babcock, which is responsible for dismantling the submarine’s radiological components. The company has also partnered with Veolia, a London-based firm, to lead the recycling efforts and facilitate the reuse of the submarine’s structural materials, including steel and sections of the reactor compartment located within the pressure hull.
Harry Holt, Chief Executive of Babcock Nuclear Sector, described the initiative as a “world first,” emphasizing the combination of nuclear expertise and collaborative industry efforts that have made this project possible. The aim is to set a new standard in the decommissioning of nuclear vessels, showcasing the potential for sustainable practices in the industry.
John Abraham, Chief Operating Officer of Veolia, echoed this sentiment, stating that the project signifies a new era of sustainability in the decommissioning and recycling of nuclear submarines. He emphasized that this effort aligns with their GreenUp strategic program, which is focused on depolluting, decarbonizing, and preserving natural resources.
The Submarine Dismantling Project, overseen by the UK Ministry of Defence’s Submarine Delivery Agency, was established to address the complexities involved in dismantling and disposing of nuclear-powered submarines. Approved in 2013, the project outlines a structured and long-term plan to safely dismantle 27 decommissioned submarines.
As of July, the Swiftsure has entered the final phases of its dismantling process at Babcock’s facility in Rosyth. This critical phase involves the careful identification and removal of any remaining classified components, coupled with meticulous testing procedures to ensure that parts of the submarine are cleared of radioactive materials. This rigorous process underscores the project’s commitment to safety and environmental responsibility throughout the decommissioning activities.
