Comparative Assessment of the NPP Risk (on the Example of Rostov and Kalinin NPP). Development of Risk Indicators Atlas for Russian NPPs

Abstract

The object of the work is to compare and analyze external and internal exposure doses and assess damage to the population living around nuclear power plants with VVER-type reactors (on the Rostov and Kalinin nuclear power plants), within a certain radius, taking into account the wind rose. There will also be proposed measures for the possible addition and refinement of formulas. The method of calculating the doses of external and internal exposure, as well as damage to the population in the ring segment of rumba. External and internal exposure doses for Kalinin and Rostov NPPs have been considered. An assessment of material damage was conducted. A variant of the format of the atlas of risk assessments is proposed. Initial assumptions have been made regarding the discrepancy in the results obtained for both doses and damage. One of the possible reasons for the discrepancy in the results of calculating the dose and damage to the Kursk and Smolensk NPPs may be the difference in the terrain. We need to take this into account. By relief changes we mean not ravines and slopes, but hills, mountains, fields. Additionally, you can consider the type of terrain: steppes, forests, etc., although all this will contribute to the already quite a long distance from the nuclear power plant. In the future, it is planned to continue work on the atlas of risk assessments and think over its more convenient format.
