Abstract

One of the keys to efficient and safe decommissioning of nuclear facilities, including long-term storage of nuclear waste and materials, is trustworthy reliable metrology. Sellafield Ltd and the UK’s National Metrology Institute (the National Physical Laboratory) have worked closely together to address several key measurement challenges related to decommissioning to facilitate for e.g., long-term reliable inspection and to support safety cases.

A number of examples are given where reliable metrology has been deployed or is being developed to facilitate such decommissioning in the challenging environments found in nuclear decommissioning and storage of waste and other materials. Metrology areas such as reliable thermometry (including surface thermometry), quantifying fuel drying, alpha particle detection, detection of corrosion and other features on waste containers and development of acoustic approaches to detect possible in-container hydrogen deflagration events will be covered.
