Office for Nuclear Regulation

Decommissioning, fuel and waste

As a part of our Sellafield, Decommissioning, Fuel and Waste division the DFW sub-division is responsible for regulating safety on 20 licensed nuclear sites and for regulating transport of radioactive material between these and other nuclear sites. DFW also leads for ONR on a number of broader topics, not specifically related to the licensed sites, these include:  providing advice to government and others on Radioactive waste management and decommissioning policy and strategy; Land quality management; and the regulatory framework for Geological disposal  of radioactive waste.

Decommissioning sites

There are 13 former power reactor and research reactor sites in various stages of Decommissioning:

There are 2 sites in the final stages of decommissioning and site clearance preparing to delicense, at:

Fuel manufacturing sites

There are 2 sites that enrich uranium and produce new fuel for nuclear power plants:

Waste treatment and disposal sites

There are two commercial sites that recycle and treat low level radioactive waste and a low-level radioactive waste disposal site:

The governmental body responsible for securing the clean-up of civil nuclear liabilities in the UK is the Nuclear Decommissioning Authority (NDA5) which owns 17 sites. DFW inspectors have regular interactions with the NDA through national and other forums, where the site licence companies are sometimes represented.  One such group is the National Decommissioning Strategy and Policy Group (NDSPG), of which ONR is a member. NDSPG is chaired by BEIS and the NDA acts as its secretariat, ONR’s role is to ensure that when decommissioning and radioactive waste management policies and strategies are developed, that they meet national and international nuclear safety standards.
