DRAWING UP OF MANAGEMENT ROUTES FOR LWR HULLS, BASED ON THE COMPACTION/PACKAGING AND EXHAUSTIVE DECONTAMINATION CONCEPTS

Objective

THIS STUDY MAKES PART OF A JOINT STUDY, WHICH AIMS AT THE ASSESSMENT OF DIFFERENT MANAGEMENT ROUTES FOR HULLS AND CAPS, GENERATED DURING THE REPROCESSING OF SPENT FUEL. THE ASSESSMENT WILL BE BASED ON ECONOMICAL AND RADIOLOGICAL CRITERIA.

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.

THE METHODOLOGY, TO BE APPLIED FOR THE EVALUATION OF THE MANAGEMENT ROUTES, CONSISTS OF THE FOLLOWING TASKS:

1. DEFINITION OF A REFERENCE SCENARIO.
2. DEFINITION OF DISCHARGE LIMITS AND WASTE ACCEPTANCE CRITERIA.
3. DEFINITION OF AMOUNTS AND CHARACTERISTICS OF HULLS AND CAPS.
4. DRAWING-UP OF THE BASIC MANAGEMENT ROUTES.
5. SENSITIVITY STUDIES ON EACH BASIC MANAGEMENT ROUTE.
6. DEVELOPMENT OF COMPUTING PROGRAMMES FOR ITEMISING AND EVALUATING THE DIFFERENT MANAGEMENT OPTIONS.
7. COSTING OF THE BASIC MANAGEMENT ROUTES, AS WELL AS THE VARIANTS EVOLVED FROM SENSITIVITY STUDIES.
8. ASSESSMENT OF THE RELATED OCCUPATIONAL EXPOSURE.
9. ASSESSMENT OF THE RELATED RADIOLOGICAL IMPACT TO THE PUBLIC.

1. DISCUSSION OF DATA CONCERNING AMOUNTS AND CHARACTERISTICS OF HULLS AND CAPS, GENERATED IN THE FRAMEWORK OF THE REFERENCE SCENARIO.

2. DRAWING-UP OF THE FOLLOWING BASIC MANAGEMENT ROUTES:
NO. 1: HULLS COMPACTION/CONDITIONING/PACKAGING/INTERIM STORAGE;
NO. 2: HULLS DECONTAMINATION/CEMENTATION/PACKAGING/INTERIM STORAGE.

3. SENSITIVITY STUDIES TO STUDY THE IMPACT OF SOME IMPORTANT PARAMETERS ON:
- WASTE PRODUCT CHARACTERISTICS AND ARISINGS;
- THE TOTAL VOLUME OF THE TREATMENT/CONDITIONING FACILITY BUILDINGS.

4. CALCULATION OF THE OCCUPATIONAL EXPOSURE FOR ROUTINE OPERATION AND MAINTENANCE: ANNUAL INDIVIDUAL DOSE AND COLLECTIVE DOSE FOR 30 YEARS OPERATION.
