Vulcan - Sub Testing

The Ministry of Defence has confirmed that the Vulcan Naval Reactor Test Establishment (NRTE) in Caithness, Scotland, will continue operating in support of the UK’s nuclear submarine programme until at least April 2027, before transitioning to decommissioning. In a written statement to Parliament on Wednesday, Maria Eagle, Minister for Defence Procurement and Industry, outlined the future of the site, which has supported nuclear propulsion testing for more than half a century. The last test reactor was shut down in 2015, and the site has since focused on fuel management and safety assurance for the Royal Navy’s nuclear-powered submarines. The announcement provides clarity on the future of the historic site, ensuring continuity of operations for the UK’s submarine deterrent in the near term while outlining a path toward final closure and clean-up.
