Objective THE OBJECTIVES OF THE WORK ARE : - TO ESTABLISH A METHODOLOGY FOR THE ASSESSMENT OF RISKS ASSOCIATED WITH HUMAN INTRUSION EVENTS APPLICABLE TO THE TYPES OF UNDERGROUND REPOSITORY STUDIED IN THE PAGIS AND PACOMA PROJECTS; - TO DELINEATE THE APPLICATION OF THE METHODOLOGY TO THE ALTERNATIVE DISPOSAL CONCEPTS, TAKING INTO ACCOUNT THE CHARACTERISTICS OF THE HOST ROCKS (CLAY, GRANITE, SALT AND SUB-SEABED SEDIMENTS) AND REPOSITORY DESIGNS; - TO PRODUCE AN AUTHORATIVE SOURCE OF REFERENCE (DATABASE AND METHODOLOGY) FOR USE IN SAFETY ASSESSMENT OF HLW AND ILW DISPOSAL FACILITIES.1. THE VARIOUS HUMAN ACTIVITIES WHICH MIGHT RESULT IN AN INTRUSION INTO A REPOSITORY, OR DISRUPTION OF THE HOST GEOLOGY LEADING TO ENHANCED RADIONUCLIDE MIGRATION, WILL BE IDENTIFIED. RELEVANT INFORMATION NECESSARY TO DEFINE AND QUANTIFY EACH MODE WILL BE COLLATED. 2. THE RADIOLOGICAL CONSEQUENCES, TO POTENTIAL INTRUDERS AND TO OTHERS, FROM DEFINED INTRUSION MODES WILL BE REVIEWED AND APPROPRIATE CALCULATION SCHEMES DEFINED. 3. THE PROBABILITIES OF INTRUSIVE EVENTS, IDENTIFIED AS SIGNIFICANT, WILL BE ESTIMATED FOR REFERENCE CIRCUMSTANCES. FACTORS AFFECTING THESE PROBABILITIES WILL BE IDENTIFIED AND QUANTIFIED AS FAR AS POSSIBLE. 4. FROM THE ANALYSIS MADE ABOVE, A GENERAL PHILOSOPHY FOR ASSESSMENT OF RISK FROM HUMAN INTRUSIONS WILL BE DEVELOPED. THE APPLICATION OF THE METHODOLOGY WILL BE OUTLINED FOR THE PARTICULAR HOST GEOLOGIES AND REPOSITORIES CONSIDERED IN PAGIS AND PACOMA, WITH THE AID OF EXAMPLES. 5. THE CAPACITY FOR REDUCTION OF RISK FROM INTRUSION BY MEASURES TO REDUCE THE PROBABILITY OR CONSEQUENCES OF INTRUSION WILL BE EXAMINED. THIS WILL INCLUDE AN EXAMINATION OF POSSIBLE ANTI-INTRUSION MEASURES.
