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.
There are 13 former power reactor and research reactor sites in various stages of Decommissioning:
- Berkeley, Bradwell, Chapelcross, Dungeness A, Harwell, Hinkley Point A, Hunterston A, Oldbury, Sizewell A, Trawfynydd, Winfrith and Wylfa all licensed to Magnox Limited; and
- Dounreay, licensed to Dounreay Site Restoration Limited (DSRL).
There are 2 sites in the final stages of decommissioning and site clearance preparing to delicense, at:
- Amersham licensed to GE Healthcare Ltd (former radiopharmaceuticals site); and
- Imperial College Research Reactor at Ascot.
Fuel manufacturing sites
There are 2 sites that enrich uranium and produce new fuel for nuclear power plants:
- Capenhurst Works, licensed to Urenco UK Ltd; and
- Springfields Works, licensed to Springfields Fuels Ltd.
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:
- Tradebe Inutec Ltd at Winfrith;
- Metals Recycling Facility operated by Cyclife UK Ltd in Lilyhall Cumbria; and
- Low Level Waste Repository (LLWR) at Drigg in Cumbria.
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.
