Název v původním jazyce

Analyses of potential consequences after a severe accident in a RBMK-1000 during the Russia-Ukraine conflict

Popis výsledku v původním jazyce

The Russia-Ukraine conflict has significantly increased safety threats, primarily due to the potential damage to nuclear facilities like the VVER-1000 (Zaporizhzhya region), RBMK-1000 (Kursk region), and even research reactors. In response to the military activities near Zaporizhzhya and Kursk Nuclear Power Plants (NPP), assessments of the possible consequences of severe accidents have been conducted, considering the impacts across Europe. To simulate the radiological consequences, a combination of simulation codes, including SCALE and JRODOS, was employed. Initially, a geometrical model of the RBMK-1000 reactor was developed using SCALE. Subsequently, an engineering estimation methodology was applied to determine a source term, representing the fission products released from the damaged fuel assemblies. Next, large-scale atmospheric radionuclide release simulations were performed using the JRODOS software, where the release conditions were modeled based on postulated assumptions. The analysis of the radiological impact on European territories was conducted utilizing actual meteorological data obtained from the NOAA Operational Model Archive and Distribution System (NOMADS).
