Eco information 5. Influence of operation of the plants Jadrova vyradovacia spolocnost, a.s., on the environment, Locality of Mochovce, within May 2021

In this leaflet the results of monitoring of radioactive gaseous and liquid effluents into the Hron River as well as of radiation monitoring of Mochovce Liquid RAW Final Treatment Facility (FS KRAO) and Mochovce Radioactive Waste Repository (RU RAO) are presented. The radioactive effluents into hydrosphere within May 2021 for the radioactive effluents into hydrosphere within for FS KRAO were: 0.000 GBq of tritium (0.004 GBq for the period January - May 2021 (0.000% of AL)) and summary of gamma radionuclides 0.000 GBq (0.000 GBq for the period January - May 2021 (0.000% of AL)). The radioactive effluents into hydrosphere within January - May 2021 for FS KRAO were: 0 kBq of ⁹⁰Sr (0 kBq for the period January - March 2021), 0.000 kBq of summary alpha within January - March 2021 (0.000 kBq of annually value) and 0 kBq of ¹⁴C for the period January - March 2021 (0 kBq of annually value). The radioactive effluents into hydrosphere within May 2021 for RU RAO were: 1.136 MBq of tritium (2.272 MBq for the period January - May 2021 (0.012% of AL)); 0.008 MBq of ¹³⁷Cs in February 2021 (0.016 MBq for the period January - May 2021 (0.070% of AL)); 0.045 MBq of ⁹⁰Sr - the value within January - March 2021(0.000 MBq (0.018% of AL)); The radioactive effluents into hydrosphere within May 2021 for RU RAO were: 0.004 MBq of ⁶⁰Co (0.008 MBq for the period January - February 2021 (0.018% of AL)); 0.000 MBq (0,003%) of ²³⁹Pu for the period January - March 2021. Volume of liquid effluents in February 2021 was 454 m³ (908 m³ for the period January - May 2021). The radioactive effluents into atmosphere within May 2021 for FS KRAO were: 5.3 kBq of gamma radionuclides (1.1 kBq for the period January - May 2021, that is 0.007% of annually limit (AL)); 0.168 kBq of summary ¹³⁷Sr - the value within January - March 2021 (0.168 kBq for the period January - March 2021 (0.008% of AL)) and 0.023 kBq of alpha radionuclides within January - March 2021 (0.023 kBq for the period January - March 2021 (0.002% of AL)).
