Abstract
Storage vessels filled with waste radioactive material are taken underground using the entrance of an operating or abandoned mine. The vessels are deposited in chambers cut into previously undisturbed rock below the `karst' water level. The chambers are filled and each chamber, section and the whole `field' is sealed off against water. Transport is always carried out against the flow of ventilation air. The underground storage area is located below the `karst' water level, in rock formation with a max. of 10 power(-6) cm/sec. water leakage, at least 100 metres from the bounary of the formation, and at least 300 metres from rock, which is already disturbed. The storage area has a max. of two connections to the surface, these are for inward transport and tie-in. The storage area is divided into sections in which access roads and storage chambers are cut. Each chamber is surrounded by protective rock. Full chambers and sectors are sealed with water tight structures
