Abstract

The decommissioning of a laboratory-scale reprocessing facility which has very high contamination and dose levels will provide an excellent opportunity to gain experience in a number of generic decommissioning techniques: visual/radiometric inspections; dose predictions; remote handling; decontamination of lead, steel and concrete using dry and wet processes; waste categorization, size reduction, monitoring and disposal. This final report outlines the chosen decommissioning strategy, the engineering design and construction of the remote equipment system, the prepatory work that has been required in the laboratory area to allow the equipment to be installed and the decommissioning operations which have been successfully undertaken in the first highly active cell to be remotely decommissioned at the Sellafield site. Many lessons have been learnt, in particular that historical data on a facility's design and use cannot always be relied on, and that proving a complex remote system in an inactive mock-up is invaluable.
