Radiological characterisation for decommissioning: international good practice and experience - 000112

The 'Expert group on Radiological Characterisation for Decommissioning' (TGRCD),under the auspices of the Nuclear Energy Agency (NEA) had provided high-level guidance for practitioners in characterisation for decommissioning. This work focused on the characterisation of radioactive waste and materials during the decommissioning of nuclear facilities. The expert group has completed the final report titled 'Radiological Characterisation from a Waste and Materials End-State Perspective: Practices and Experience'. The report is written for characterisation practitioners who carry out the tactical planning, preparation, optimisation and implementation of characterisation to support the decommissioning of nuclear facilities and the management of associated materials and waste. It compiles recent experience of NEA member countries in radiological characterisation, including the experience of international experts and practitioners; the learning from international case studies and international conferences; and national approaches to the application of international and national regulations, standards and guidance documents. Using this comprehensive approach and evaluation studies, the report identifies relevant good practices and sets out practical guidance covering all stages of the characterisation process as related to decommissioning.
