DRAWING-UP OF MANAGEMENT ROUTES FOR LWR-HULLS BASED ON THE DIRECT CEMENTATION AND MELTING CONCEPTS

Objective

THE OBJECTIVE OF THE 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:

- ROUTE NO 1: HULLS AND CAPS CEMENTATION/PACKAGING/INTERIM STORAGE (REFERENCE INDUSTRIAL ROUTE OF THE LA HAGUE REPROCESSING PLANT).

- ROUTE NO 2: HULLS MELTING IN A COLD CRUCIBLE, CAPS MELTING IN CONVENTIONAL CRUCIBLE/PACKAGING/INTERIM STORAGE (ALTERNATIVE ROUTE UNDER DEVELOPMENT).

IN ORDER TO EVALUATE MANAGEMENT ROUTES FOR HULLS AND CAPS, A METHODOLOGY IS APPLIED WHICH CONSISTS IN PERFORMING THE FOLLOWING SEQUENCE OF TASKS:

1. DEFINITION OF A REFERENCE SCENARIO (SIZE OF THE NUCLEAR PARK, REACTOR TYPE, FUEL BURN-UP, COOLING TIME BEFORE REPROCESSING).
2. DEFINITION OF BASIC HYPOTHESIS CONCERNING DISCHARGE LIMITS AND WASTE ACCEPTANCE CRITERIA FOR DISPOSAL.
3. DEFINITION OF THE CHARACTERISTICS AND ARISINGS OF HULLS AND CAPS.
4. DRAWING UP OF BASIC MANAGEMENT ROUTES TAKING INTO ACCOUNT TREATMENT AND CONDITIONING VARIANTS.
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 (SHORT AND LONG TERM).

WITH RESPECT TO THE OTHER TASKS, CEN/VALHRO TAKE IN CHARGE WHOLLY TASKS 3, 4, 5 AND 8 PARTLY TASK 9 FOR TWO BASIC MANAGEMENT ROUTES BASED ON DIRECT HULLS CEMENTATION FOR THE FIRST ONE AND ON MELTING FOR THE SECOND ONE.
