The National Radioactive Waste Repository is a multi-barrier surface type disposal facility, the purpose of which is the disposal of solid and solidified low-level RAW from the operation and decommissioning of NPPs, or from research institutes, laboratories and hospitals, from all over the Slovak Republic.
The disposal facility is a system consisting of disposal boxes, arranged in rows and double-rows. Double-rows are covered by a steel hall. Ninety (90) fibre-concrete containers, each measuring 1.7 × 1.7 × 1.7 m with a wall 0.1m thick can fit into one disposal box. From the beginning of its operation by the 31st of December 2018, 5,474 fibre-concrete containers with RAW have been disposed of at the National Radwaste Repository.
