State Enterprise “Radioactive Waste” CHALLENGES – Development of Deep Geological Repository for Spent Fuel and High Level waste 





Objectives  To select a suitable area/locality for final disposal of HLW and SF: deep geological repository (DGR) Approaches  Stepwise assessment of the Bulgaria territory according to established selection scheme  Selection scheme is based on:  Preferrences  Requirements  Criteria Usability of similar scheme also for surface repository site selection process

State Enterprise “Radioactive Waste” CHALLENGES – Development of Deep Geological Repository for Spent Fuel and High Level waste Selection scheme principles

 Preferrences (recomendations)

-generally accepted principles and conditions of geological settings suitability  Requirements

-specified principles and conditions of geological settings suitability, obligation to fulfill  Criteria

-qualitative and quantitative defined conditions of assessment criteria, limitations for site selection

State Enterprise “Radioactive Waste” CHALLENGES – Development of Deep Geological Repository for Spent Fuel and High Level waste

Basic principles of selection DGR

geological and geomorphological conditions hydrogeological conditions geochemical conditions engineer-geological and geotechnical conditions and feasibility spontaneous natural changes in the future potential anthropogenic negative influence waste transport environmental protection economical and social aspects
