About the Inventory
The Inventory is a snapshot of radioactive wastes and materials taken at a specific point in time, called the ‘stock date’. Updated every three years, it’s where you’ll find data, documents and information on the radioactive waste and materials that exist now and that we expect to generate as we deliver our mission to clean-up the UK’s earliest nuclear sites safely, securely and cost effectively on behalf of the government.
