Abstract

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