Abstract

 Omówiono stan prac nad składowaniem odpadów jądrowych w głębokich formacjach geologicznych. Przedstawiono koncepcje składowania głębokiego odpadów jądrowych w Polsce. Rozpatrzono dwie lokalizacje: jedną w cechsztyńskich solach pokładowych w północnej Polsce, drugą w skałach archaicznych i dolnopaleozoicznych podłoża krystalicznego we wschodniej Polsce. Podkreślono rolę analizy bezpieczeństwa przy wyborze środowiska skalnego dla lokalizacji odpadów jądrowych od biosfery. Zwrócono szczególną uwagę na konieczność precyzyjnego rozpoznania warunków wodnych jako podstawowego elementu bezpieczeństwa składowania. GEOLOGICAL CONDITIONS IN DESIGNING UNDERGROUND RADIOACTIVE WASTE DUMPSThe paper presents the progress in studies on safety of disposal of radioactive waste in deep-seated geological formations. Subsequently there are discussed the major hazards which may be expectedwhen such deep-seated dumps are constructed in Poland in order to isolate high-, medium- and low-radioactivity waste from biosphere. The waste will be coming from nuclear power plants.In Poland, works connected with designing waste disposal sites are nowadays at the stage of analysis of concepts of surface dumping and underground burial of the waste. When the latter solution is chosen, further studies will be aimed at two tentatively accepted locations: one in layered Zechstein rock salt deposits in northern Poland and the other – in Archaic and Lower Paleozoic crystalline basement rocks in eastern Poland. In both case the rocks chosen as appropriate for construction of disposal sites are overlain by strongly water-saturated rock series, with hydraulic contacts between individual aquifers.Attention is paid to the necessity of careful surveying the hydrogeological conditions as the major prerequisite of safety in waste storage. The present knowledge of hydrogeological conditions impedes identification of major potential water hazards and related possibilities of migration of critical nucleidsfrom the dump to surface. The major hazards may be connected with insufficient sealing in time of construction and filling-up shafts and an excessive effect of thermal field of high-radioactivity waste dump on surrounding rock massif. The latter is mainly the case of waste storage in rock salt deposit.
