Obiettivo THE OBJECTIVE OF THIS RESEARCH IS TO CONDUCT A BROADLY-BASED STUDY IN WHICH A METHODOLOGY IS DEMONSTRATED FOR ASSESSING AS MANY AS POSSIBLE OF THE FACTORS RELEVANT TO DECISIONS ON THE MANAGEMENT OF ALL THE MAJOR TYPES OF WASTE ARISING IN STAGES 2 AND 3 OF DECOMMISSIONING. THE METHODOLOGY WILL INCLUDE THE USE OF DECISION-AIDING TECHNIQUES AND WILL SHOW HOW QUANTITAIVE AND QUALITATIVE FACTORS CAN BE WIEIGHED AGAINTS EACH OTHER, IN ORDER TO PROVIDE GUIDANCE TO THOSE RESPONSIBLE FOR TAKING DECISIONS. THE METHODOLOGY WILL BE ILLUSTRATED BY EXAMPLES BASED ON SEVERAL DIFFERENT TYPES OF REACTOR. In order to compare different decommissioning options, various impacts associated with decommissioning operations and waste disposal were assessed, namely financial cost and radiological, environmental and sociopolitical impact. With the exception of post-disposal radiological impact, broadly representative data from the literature were used. The postdisposal radiological impact was calculated for 4 generic disposal concepts (near surface, deep geologic, coastal tunnel and deep ocean bed) using established National Radiological Protection Board (NRPB) models for the transfer of radionuclides through the environment to man. In general, environmental and social factors cannot be quantified in the way costs and doses can be, so these were assessed semiquantitatively or qualitatively; quantitative judgements were left to the comparison stage.B.1.- DEFINITION AND DESCRIPTION OF FACTORS RELEVANT TO WASTE MANAGEMENT DECISIONS INCLUDING RADIOLOGICAL HAZARD, SOCIO-POLITICAL FACTORS AND COST EFFECTIVENESS. B.2.- DEFINITION OF ALL RADIOACTIVE WASTES ARISING FROM STAGE 2 AND 3 DECOMMISSIONING OF TYPICAL PWRS, AGRS, AND MAGNOX REACTORS. B.3.- DEFINITION OF SUITABLE MANAGEMENT SYSTEMS FOR IMMEDIATED AND DELAYED DISMANTLING AND FOR VARIOUS DISPOSAL AND RECYCLING-REUSE ROUTES. B.4.- ASSESSMENT OF THE RADIOLOGICAL IMPACT OF EACH MANAGEMENT SYSTEM TO WORKERS AND MEMBERS OF THE PUBLIC. B.5.- ASSESSMENT OF OTHER ENVIRONMENTAL FACTORS ASSOCIATED WITH EACH MANAGEMENT SYSTEM, INCLUDING NON-RADIOACTIVE POLLUTANTS, TRANSPORT, CONVENTIONAL SAFETY AND EFFECTS ON RESOURCES. B.6.- ASSESSMENT OF SOCIAL AND POLITICAL FACTORS ASSOCIATED WITH EACH MANAGEMENT SYSTEM, SUCH AS PUBLIC ACCEPTABILITY AND INTERNATIONAL CONCERNS. B.7.- ASSESSMENT OF THE COST OF WASTE TREATMENT, TRANSPORT AND DISPOSAL, ASOCIATED WITH EACH MANAGEMENT SYSTEM. B.8.- DEMONSTRATION OF THE METHODOLOGY ON THE THREE REACTOR TYPES TO IDENTIFY THE DOMINATING DECISION-AIDING FACTORS AND THE PRIORITIES FOR FURTHER WORK.
