IT IS EXPECTED TO ACCUMULATE LARGE QUANTITY OF TRANSURANIC WASTES (AND LONGLIVED
/
LOW LEVEL RADIOACTIVE WASTES). IN THE CIRCUMSTANCES,ATOMIC ENERGYCOMMITTEE RECOMMENDED THAT IT IS NECESSARY TO PRESENT APPLICABLE TECHNOLOGY FORISOLATING TRANSURANIC WASTE TILL 2000.THE LONG TERM SAFETY OF ISOLATION TECHNOLOGY MUST BE CONVINCINGLY ASSESSED PRIORTO ITS APPLICATION. THEREFORE MODELS WHICH CAN PREDICT RELEASE AND MIGRATION OFRADIONUCLIDES WITH ADEQUATE ACCURACY NEED TO BE DEVELOPED AND VALIDATED. IN THISINVESTIGATION,THE PURPOSE OF WHICH IS TO IDENTIFY PRINCIPAL PHENOMENA FORPERFORMANCE ASSESSMENT AND TO INTEGRATE SIMPLIFIED SYSTEM MODELS FOR OVERALLSAFETY ASSESSMENT.IN 1993 FOUR SUBJECTS LISTED BELOW WERE INVESTIGATED.(1)SCENARIO DEVELOPMENT FOR PERFORMANCE ASSESSMENT OF TRU WASTE ISOLATION.(2)INVESTIGATION OF ASSESSMENT METHODS FOR IMPORTANT PHENOMENA OF TRU WASTEISOLATION.(3)PRELIMINARY ASSESSMENT FOR GAS GENERATION FROM TRU WASTES.(4)DEVELOPMENT OF TOTAL PERFORMANCE ASSESSMENT METHDOOLO
