Publication of Research Results in Radiocarbon

     In January 2023, the article “Traces of 14C emissions for the operation period of two Ukrainian NPPs: Rivne and Chornobyl” was the State Institution ” O. M. Marzieiev Institute for Public Health” of the NAMS of Ukraine”, the Institute for Safety Problems of Nuclear Power Plants of the NAS of Ukraine, the Rivne NPP of the NNEGC “Energoatom”, as well as the State Institution “Dobrov Research Institute on Scientific and Technological Potential and Science History” of the NAS of Ukraine. The co-author of the article is the Head of the Geoecological Researches Sector, Ph.D. in Tech. Sc. Mykola Panasiuk.

     The aim of this study was a comparative retrospective assessment of radiocarbon (14C) as a tracer, caused by operational emissions of Rivne and Chornobyl nuclear power plants (NPPs), which are equipped with different types of nuclear reactors. For this purpose, 14C was studied in annual tree rings of pine taken at a distance of 1.5 km southwest of the Rivne NPP and at a distance of 3.5 km west-northwest of the Chornobyl NPP, near the Yaniv railway station.

    It was found that the 14C excess in the annual tree-ring samples of pine near the Chornobyl NPP during the observed operation period (1984–2000) was 3.0–13.0 pMC, except for the 1986, the year of the Chornobyl accident, when the 14C value rose sharply to 182.7 pMC (14C excess 62 pMC). After 2000, the content of 14C in the air near the Chornobyl NPP did not exceed the background values within the uncertainty of the measured data. The concentration of 14C in the samples of annual tree rings of pine near the Rivne NPP for the observation period (1986–2019) corresponded to the background levels within the uncertainty of the measured data. The study of environmental traces of 14C emissions from two NPPs equipped with different types of reactors showed significantly lower emissions of Rivne NPP with VVER compared with emissions from Chornobyl NPP with RBMK reactors.
