We are committed to disposing of our nuclear submarines in a way that is safe, environmentally responsible, secure and cost-effective.

The purpose of the Submarine Dismantling Project (SDP) is to develop a solution for the disposal of the UK’s nuclear submarines after they have left service with the Royal Navy. This Ministry of Defence project extends over a 60 year period and includes the provision of facilities to dismantle 27 defueled nuclear submarines of past and current classes. It was formerly known as the ISOLUS (Interim Storage of Laid-Up Submarines) project.

Most of the material from each submarine will be recyclable; however, there will be some radioactive and non-radioactive hazardous wastes that will need to be dealt with, in keeping with strict legislative and regulatory requirements. The project includes the interim storage on land of the resulting Intermediate Level Radioactive Waste until it is transferred into a planned long-term geological disposal facility. It also includes the eventual decommissioning of the dismantling and storage facilities themselves.

The Submarine Dismantling Project is undertaking further Statutory Consultation with Government bodies to consider the detailed scope of the SEA – which identifies and considers any potentially significant environmental effects of submarine dismantling - including the potential candidate sites for the removal of the radioactive elements of the submarine.
