Abstract

MOIRA-PLUS is a decision support system (DSS) designed to address the mid and long-termissues after nuclear accidents causing the contamination of freshwater bodies andcatchments with radionuclides. It is designed to allow for a reliable assessment of thelong-term evolution of the radiological situation and of possible alternativerehabilitation strategies, including an objective evaluation of their social, economic andecological impacts in a rational and comprehensive manner. MOIRA also features a decisionanalysis methodology, making use of multi-attribute analysis, which can take into accountthe preferences and needs of different types of stakeholders. The main functions andelements of the MOIRA-PLUS DSS are described summarily, together with the conclusions fromend-user’s experiences with the system. MOIRA-PLUS has proven to be a mature system, userfriendly and relatively easy to set up. It can help to reassure the public by enabling arealistic evaluation of the complete impacts of possible recovery strategies. However, theusers also identified possibilities for further improvement of the DSS.
