Abstract

IN PAGIS PROJECT THE SAFETY OF THE GEOLOGICAL DISPOSAL SYSTEM FOR VITRIFIED HIGH LEVEL WASTE IS BASED ON THE MULTIBARRIER CONCEPT. THIS IS REFLECTED IN THE CALCULATIONS WHERE FOR ALL OPTIONS THE BEHAVIOUR OF EACH BARRIER IS MODELLED. IN THE PRESENT SCHEME ALL THE MODELS USED FOR THE PERFORMANCE ASSESSMENT OF THE DISPOSAL OPTIONS HAVE BEEN CONSIDERED AS A CHAIN OF CODES DESCRIBING THE BEHAVIOUR OF THE DIFFERENT BARRIERS. FOR EACH OF THESE, ONE OR MORE POSSIBILITIES OF VERIFICATION BY NATURAL ANALOGUE (NA) IS PRESENTED. A SET OF TABLES HAS BEEN PREPARED WHICH SHOWS THE SEQUENCE OF PHENOMENA CONSIDERED FOR EACH DISPOSAL OPTION. A REVIEW OF THE NA AS SO FAR STUDIED OR SIMPLY RECOGNISED ALLOWED A CHECK TO BE MADE ON THE POSSIBILITY OF VERIFICATION OF THE BARRIER MODELS WITH THE "LONG TERM EXPERIMENTS" OFFERED BY THE GEOLOGICAL EVIDENCE.
