Decontamination and decommissioning developments and experiences in the UK

The paper illustrates some of the decommissioning experiences gained by BNFL with its United Kingdom operations. It includes a brief description of a number of projects at the Company's reprocessing site at Sellafield, the full decommissioning through to delicensing of the Universities Research Reactor at Risley, Warrington and the planning and initial work for the decommissioning of the Triga Mk I Reactor at ICI Billingham. The paper concludes with a summary of the necessary technology and development projects undertaken to support the decommissioning operations to date and the advances made by BNFL in the accurate cost estimation of achieving these objectives.
