Objective THE OBJECTIVE OF THIS CONTRACT IS TO CONTRIBUTE TO THE IMPLEMENTATION OF A JOINT STUDY ON MANAGEMENT OPTIONS FOR HULLS AND CAPS BY DRAWING UP TWO BASIC ROUTES EMPHASIZING THE TREATMENT/CONDITIONING AND PACKAGING ASPECTS. A MANAGEMENT ROUTE IS DEFINED AS EACH ASSEMBLY OF CO-ORDINATED ACTIONS BY WHICH THE MANAGEMENT OF HULLS AND CAPS FROM THEIR PRODUCTION TO THEIR DISPOSAL IS IMPLEMENTED. USUALLY, THESE ACTIONS COMPRISE TREATMENT, CONDITIONING, PACKAGING, INTERIM STORAGE, TRANSPORT AND DISPOSAL OPERATIONS. SINCE THIS JOINT STUDY WILL ADOPT THE METHODOLOGY FOLLOWED IN A PREVIOUS ONE, DEVOTED TO TWO OTHER SPECIFIC ALPHA WASTES (SOLID PLUTONIUM CONTAINING WASTE AND REPROCESSING SLUDGES), IT WILL BE REFERRED TO IT FOR THE DEFINITION OF THE REFERENCE SCENARIO, THE BASIC HYPOTHESIS AND THE PROCEDURE TO BE CARRIED OUT FOR ASSESSING COST AND RADIOLOGICAL IMPACT TO THE PUBLIC. THE TASKS OF NUKEM IN THIS CONTRACT ARE: - DEFINITION OF CHARACTERISTICS AND ARISINGS OF HULLS AND CAPS, PARTLY, - DRAWING-UP OF 2 BASIC MANAGEMENT ROUTES TAKING INTO ACCOUNT TREATMENT AND CONDITIONING, - SENSITIVITY STUDIES ON EACH BASIC MANAGEMENT ROUTES, - DETERMINATION OF GEOLOGICAL DISPOSAL COSTS AT GORLEBEN, - ASSESSMENT OF THE RELATED OCCUPATIONAL EXPOSURE. 1. HULLS AND CAPS CHARACTERISTICS AND ARISINGS FOR THIS TASK, IT IS ONLY ASKED TO NUKEM TO DISCUSS THE DATA PROVIDED BY AN OTHER ORGANISATION PARTICIPATING IN THE JOINT STUDY, SO THAT A REFERENCE WASTE COMPOSITION CAN BE AGREED UPON WITHIN THE WORKING GROUP. 2. DRAWING-UP OF BASIC MANAGEMENT ROUTE NUKEM EXTENSIVELY DEFINES TWO BASIC ROUTES: ROUTE NO. 1: HULLS, CAPS COMPACTION/CEMENTATION/PACKAGING/INTERIM STORAGE ROUTE NO. 2: HULLS, CAPS COMPACTION/EMBEDDING IN GRAPHITE ETC. 3. SENSITIVITY STUDIES FOR BOTH THE MANAGEMENT ROUTES SENSITIVITY STUDIES ARE PERFORMED BY VARIATIONS OF THE MOST IMPORTANT PARAMETERS AS INDICATED IN THE WORK PROGRAMME. 4. COST EVALUATION AS FAR AS DISPOSAL OF CONDITIONED AND PACKAGED HULLS IN THE GORLEBEN SALT DOME IS CONCERNED, NUKEM WILL PROVIDE DATA ON THE RELATED DISPOSAL COST. THIS WILL BE EXPRESSED IN ECU/M3 OF CONDITIONED WASTE. 5. ASSESSMENT OF THE OCCUPATIONAL EXPOSURE FOR THE TWO BASIC ROUTES OF CONCERN, THE OCCUPATIONAL EXPOSURE WILL BE DETERMINED FOR ROUTINE OPERATIONS INCLUDING MANUAL OPERATIONS FOR REPAIRS AND MAINTENANCE, PACKAGING, TRANSPORT AND DISPOSAL AT GORLEBEN. ON ACCOUNT OF THE IMPORTANCE OF THE CONDITIONING/DISPOSAL CRITERION ON THE TOTAL MANAGEMENT COST OF LWR HULLS, NUKEM WAS ASKED TO COMPLEMENT ITS CONTRIBUTION IN THIS FIELD BY REVIEWING AND EVALUATING THE ECONOMIC IMPACT OF THE DIFFERENT CRITERIA ALREADY FIXED OR ENVISAGED FORV THIS KIND OF WASTE PRODUCTS IN EUROPE. THE AMENDMENT TO THE CURRENT WORK PROGRAMME ALSO DEALS WITH UPDATED COST EVALUATION OF THE KONRAD MINE AND THE GORLEBEN SALT DOME ON THE BASIS OF NEW DATA ON COST COMPONENTS RECENTLY MADE AVAILABLE BY THE PTB.
