According to its origin, radwaste from nuclear power plant can be categorized as operational waste and waste produced during plant decommissioning. Nuclear power plant with four VVER-440 reactors produces 130 up to 180 m3 of solid and approximately 500 m3 of liquid low- and medium-level active radwaste annually, i.e., within 30 years of operation it is app. 3900 up to 5400 m3 of solid and app. 15000 m3 of liquid radwaste. To this amount it needs to be added more than 14 thousands of assemblies of spent nuclear fuel which represents about 3000 ton. During plant operation itself in the course of 30 years considered, more than 150 ton of high-level active operational radwaste is generated.
