PERFORMANCE EVALUATION OF CONFINEMENT FOR ALPHA-WASTE REPOSITORY IN GRANITE FORMATION (PACOMA PROJECT).

Objective

THE GENERAL OBJECTIVE IS THE SAFETY ASSESSMENT OF A DEEP REPOSITORY IN GRANITIC FORMATIONS FOR ALPHA WASTES.
THIS WORK HAS CONSISTED IN A FIRST TIME IN THE DEFINITION OF A DETAILED WASTE INVENTORY FOR ALPHA BEARING WASTE AND IN THE ADAPTATION TO THE ALPHA CASE OF THE SOURCE-TERM MODEL CONDIMENT DEVELOPED FOR THE PAGIS PROJECT (VITRIFIED WASTES).

-1. BASIC DATA : A NEW WASTE INVENTORY HAS TO BE PROVIDED. THE SITES ARE THE SAME AS IN PAGIS (AURIAT, BARFLEUR, NATIONAL UK SITE). THE REPOSITORY DESIGN HAS TO BE DEFINED FOR ALPHA-BEARING WASTES.

-2. THE METHODOLOGY WILL BE SIMILAR TO WHAT WAS DONE FOR THE PAGIS PROJECT, (DETERMINISTIC, SENSITIVITY AND UNCERTAINTY ANALYSIS).

-3. MODEL AND CALCULATIONS TOOLS : AS FAR AS POSSIBLE, THE SAME AS FOR PAGIS; A NEW VERSION OF THE SOURCE MODEL (CONDIMENT) HAS TO BE REALIZED.

-4. CALCULATIONS : SIMILAR TO WHAT HAS BEEN DONE FOR THE PAGIS PROJECT.
