PERFORMANCE ASSESSMENT OF CONFINEMENTS FOR MLW AND ALPHA WASTE

Objective

THE OVERALL OBJECTIVES OF THE UK CONTRIBUTION TO THE PACOMA PROJECT ARE TO DEVELOP AND DEMONSTRATE PROCEDURES FOR ASSESSING THE RADIOLOGICAL IMPACT OF DISPOSAL OF INTERMEDIATE LEVEL WASTE IN A DEEP REPOSITORY LOCATED IN A CLAY FORMATION. THE HYPOTHETICAL REPOSITORY CONSIDERED IS ASSUMMED TO BE AT HARWELL IN OXFORDSHIRE. THE RESEARCH IS CO-ORDINATED BY THE UK DEPARTMENT OF ENVIRONMENT AND CEC AND IS BEING CARRIED OUT BY FOUR ORGANISATIONS :
NATIONAL RADIOLOGICAL PROTECTION BOARD (NRPB)
THEORETICAL PHYSICS DIVISION, UKAEA HARWELL LABORATORY
ELECTROWATT ENGINEERING LTD
PRINCIPIA MECHANICA
THE NRPB WORK IS IN TWO PHASES. THE OBJECTIVES IS PHASE I ARE TO ESTABLISH A DETAILED METHODOLOGY FOR THE ASSESSMENT, TO COLLECT DATA FOR BIOSPHERE MODELLING AND TO CARRY OUT PRELIMNINARY CALCULATIONS. IN PHASE II THE AIM IS TO CARRY OUT THE ASSESSMENT, USING INFORMATION PROVIDED BY OTHER UK CONTRACTORS AND IN CONSULTATION WITH OTHER PARTICIPANTS IN PACOMA, PARTICULARLY CEN/SCK.

B.1. ADAPTATION OF PAGIS METHODOLOGY FOR USE IN THE ASSESSMENT OF INTERMEDIATE LEVEL WASTE DISPOSAL, IDENTIFICATION OF RADIONUCLIDE RELEASE SCENARIOS.
B.2. REVIEW OF AVAILABLE BIOSPHERE DATA, AND PRELIMINARY CALCULATIONS FOR TYPICAL RELEASES.
B.3. DETAILED PLANNING OF CALCULATIONS TO BE CARRIED OUT IN THE FULL ASSESSMENT, FINALISING BIOSPHERE DATA AND ASSUMPTIONS FOR EACH SCENARIO.
B.4. BEST ESTIMATES OF DOSES AND RISKS TO INDIVIDUALS AND POPULATIONS FOR EACH SCENARIO.
B.5. SENSITIVITY AND UNCERTAINTY CALCULATIONS.
B.6. CO-ORDINATION OF FINAL JOINT REPORT OF THE ASSESSMENT.
