RainMan - A methodology for the evaluation of decommissioning waste

The main objective of this study, promoted by ANPA, the Italian Nuclear Regulatory Body, carried out with ANSALDO and in close co-operation with SOGIN, was to define a methodology for the evaluation of the inventory of the amount of radioactive waste produced during the NPPs decommissioning activities, in terms of both volume and radioactivity content, and estimate the solid materials suitable for release from the regulatory control. The simulation code RainMan, developed within this project, allows, according to a selected scenario, for the evaluation of the solid materials that could be cleared and the volumes of the L-MLW that should be sent to a disposal facility.
