In collaboration with the National Radiological Protection Board, AEA Technology have carried out research programme support work to the European Commisison, in the development of methodologies to evaluate the risks of decommissioning nuclear facilties and disposal of the resulting waste materials.
In Part A, the feasibility of establishing a decommissioning safety database for use in deterministic or probabilistic safety analysis was examined. The study examined general data requirements for decommissioning safety analysis and identified data that were currently available. The study concluded that in principle a database could be established. However, to obtain the maximum benefit, careful organization would be needed to define, identify and collect the relevant data, especially on an international scale. Commercial interests could prove to be a barrier.
Part B was concerned with identifying the optimum strategy for decommissioning plutonium contaminated gloveboxes. Previously developed decision-aiding and risk assessment methodologies were employed with a view to systematically assessing the various options available. Radiological safety, economics and social and project-specific factors were examined. The results of the analysis indicate that decision-aiding techniques can show: the important factors which need consideration; the trade-offs which must be made in choosing between options; options which are unlikely to warrant further consideration. .
