“…However, concentration of radioactive substances at the distance of over 1000 m from the sources of release will not be significantly different from the concentrations induced by global fallouts (Fig. 4) (Sarkisov et al 2018).…”

“…Nuclear reactors, reactor compartments of nuclear submarines and screen assembly of the Lenin nuclear icebreaker (Sarkisov et al 2015) sunken at the bottom of the Arctic Ocean in the Kara Sea in 1960-70-ies were examined as model cases in the course of studies and assessment of risk of environmental impact in case of sinking nuclear and radiation dangerous objects. Model and software means were developed for estimating time of expected destruction of protective barriers of such objects by corrosion (Sarkisov et al 2018). Data on the multi-layer shielding (protective containment, physical boundaries of the cooling loop, fuel pin cladding, fuel composition), accumulated activities, outside dimensions and structural materials corresponding to the sunken object were used as the input information.…”

“…Here, the algorithm for calculation of corrosion destruction of protective barriers for simple objects (steam generators, reactor vessels and lids, etc.) amounted to the calculation of the time for the development of penetrating holes and complete dissolution of objects, while that for complex objects (sealed reactor vessels and reactor compartments) amounted to the analysis of possible ways for penetration of sea water and stage-by-stage corrosion destruction of all encountered barriers (Sarkisov et al 2015, Sarkisov et al 2018, Sivintsev et al 2005, Reistad Ole and Ilgaard Povl 2006. Quantitative estimation of consequences from the object residing on the sea bottom is based on the modeling of each of the stages of degradation: corrosion process -penetration of radionuclides in the marine environment -spread of radioactivity and isotopic composition of the contaminants.…”

The demands for nuclear power technologies in the Arctic for solving social and economic problems of the state can only be satisfied if adequate strategies of their safe handling at all stages from design to decommissioning are defined, methodological approaches and mathematical models for predicting and minimizing adverse environmental impacts of potential emergency situations at such facilities are developed, and scientifically-based results yielded within a decision-making support system for the elimination of such emergencies are applied. Special relevance of these requirements is determined by unique features of the Arctic nature and its role in the generation of climatic and hydrological processes in the World Ocean. Main results and generalized conclusions based on the analysis of radiological consequences of the large-scale application of nuclear power industry for the benefit of economic development of the Arctic region are provided in the present paper. The analysis was performed within the framework of the complex research project “Development of the methodological approaches and mathematical models to access the environmental impact of the possible accidents at the floating nuclear power objects, model calculations of the radiation propagation in the Arctic aquatic territories in case of emergency situations”. The increasing demand for the low-power nuclear power plants for the benefit of development of remote areas, the technological and economic advantages of such power plants as well as minimal possible environmental consequences of the hypothetic accidents resulted in the qualitative changes in the attitude towards their usage. Estimation was made of the scale of application of nuclear power and results were obtained of numerical modeling of distribution of reactivity in case of accidents. The conclusion was drawn on the necessity to adhere to the low-power nuclear energy generation development strategy based on the modular design concept.
