The National Radioactive Waste Repository is a multi-barrier surface type storage facility, the purpose of which is the final storage of solid and solidified low and intermediate activity RAW from the operation and decommissioning of NPPs, or from research institutes, laboratories and hospitals, from all over the Slovak Republic.
A suitable location for the facility has been selected, following engineering-geological and hydro-geological prospecting. The selection criteria were in compliance with current legislation, IAEA safety procedures, requirements for the placement of nuclear facilities, while also taking into consideration the actual proposed design of the facility and the properties and the type of the radioactive waste to be stored. The storage was put into service in 2001.
The storage facility comprises an array of storage boxes, arranged in rows and double rows. The first double row is shielded by a steel hall. The Boxes are made of steel-reinforced concrete, measuring 18 × 6 × 5.5 m, the walls are 600 mm thick. In stage 1, two double rows, i.e. 80 storage boxes were constructed. Ninety fiber-reinforced concrete containers can be fitted into one box with each of the containers measuring 1.7 × 1.7 × 17 m, the walls of the containers being 0.1 m thick. The total capacity is 7,200 containers with a total volume of 22,320 m3.
The storage facility is receiving treated low and intermediate activity waste, sealed with a cement mixture, in fiber-reinforced concrete containers that are brought in from the Bohunice Treatment Center as well as the Mochovce LRW FTF. After initial inspection, marked containers are unloaded from the transport into a storage box, to a predetermined position.
Due to the premature shutdown of the two V1 NPP units at Jaslovské Bohunice, the need for constructing new storing capacities for the deposition of radioactive waste from the decommissioning, within the existing NRWR Mochovce site, is growing. Currently, the EIA process (Environmental Impact Assessment) for this expansion is running and new storage capacities for storing low and intermediate activity waste as well as very low activity waste are expected to become available at the NRWR by the end of 2017.
