Obiettivo THE OVERALL AIM OF THE WHOLE JOINT PROJECT IS TO COMPARE, ON THE BASIS OF THE COSTS AND RADIOLOGICAL IMPACT OF THE MANAGEMENT AND DISPOSAL OF ALL THE ASSOCIATED WASTES, REPROCESSING OF PWR FUEL WITH ITS DIRECT DISPOSAL BY EMPLACEMENT IN A DEEP GEOLOGICAL FORMATION ON LAND. FOR THE REPROCESSING CASE, THE WASTES TO BE CONSIDERED INCLUDE GASEOUS AND LIQUID EFFLUENTS DISCHARGED ROUTINELY DURING REPROCESSING, SOLID LOW AND INTERMEDIATE LEVEL WASTES ARISING AT THE REPROCESSING PLANT, AND VITRIFIED HIGH LEVEL WASTE. THE LATTER WILL ALSO BE ASSUMED TO BE DISPOSED OF BY EMPLACEMENT IN A DEEP GEOLOGICAL FORMATION. THE STUDY WILL INCLUDE AN ANALYSIS OF THE SENSITIVITY OF THE RESULTS TO VARIATIONS IN KEY ASSUMPTIONS, SUCH AS THE TIME FOR WHICH SPENT FUEL IS STORED PRIOR TO REPROCESSING. RADIONUCLIDE INVENTORIES WILL BE PROVIDED FOR ALL THE WASTES ARISING FROM REPROCESSING, AND ESTIMATES WILL BE MADE OF THE COSTS OF MANAGEMENT AND DISPOSAL OF THESE WASTES BASED ON UK EXPERIENCE AND STUDIES. VITRIFIED HIGH LEVEL WASTE WILL BE ASSUMED TO BE EMPLACED IN A GRANITE FORMATION AND SOLID LOW AND INTERMEDIATE LEVEL WASTES IN AN INTERMEDIATE DEPTH REPOSITORY IN A CLAY FORMATION. THE RADIOLOGICAL IMPACT ON THE PUBLIC OF THE MANAGEMENT AND DISPOSAL OF ALL REPROCESSING WASTES, AND OF DIRECT DISPOSAL OF SPENT FUEL IN A GRANITE FORMATION WILL BE ASSESSED. THE COST OF DIRECT DISPOSAL OF SPENT FUEL IN A GRANITE FORMATION WILL ALSO BE ESTIMATED. 2 waste management options have been studied, the direct disposal of spent nuclear fuel and reprocessing of that fuel. This report describes the calculation of the radiological impact on the public of the management and disposal of the wastes associated with each of these 2 options. 6 waste streams wereconsidered, namely, discharge of liquid reprocessing effluents, discharge of gaseous reprocessing effluents, disposal of low level solid wastes arising from reprocessing, disposal of intermediate level solid wastes arising from reprocessing, disposal of vitrified high level reprocessing wastes and direct disposal of spent fuel. The results of the calculations are in the form of maximum annual doses and risks to individual members of the public, and collective doses to 4 population groups, integrated over 6 time periods. These results were designed for input into a computer model, which combines costs and impacts in a multiattribute hierarchy to give an overall measure of the impact of a given option.The calculation of the radiological impact on the public of the management and disposal of spent fuel wastes, associated with the options of direct disposal or reprocessing, is described. 6 waste streams were considered:discharge of liquid reprocessing effluents;discharge of gaseous reprocessing effluents;disposal of low level solid wastes arising from reprocessing;disposal of intermediate level solid wastes arising from reprocessing;disposal of vitrified high level reprocessing wastes;direct disposal of spent fuel.The results of the calculations are in the form of maximum annual doses and risks to individual members of the public, and collective doses to 4 population groups, integrated over 6 time periods. These results were designed for input into a computer model which combines costs and impacts in a multiattribute hierarchy to give an overall measure of the impact of a given option.1.
