The leading design organizations of the Russian nuclear industry develop nuclear power facilities to satisfy almost any segment of the energy market. Within the framework of the Proryv project direction, a new technological platform for nuclear power is being created based on nuclear power plants with high-capacity reactors and a closed nuclear fuel cycle. Demand for fast reactors in the Russian Federation was thoroughly justified in the 2018 Strategy for the Development of Nuclear Power in the Russian Federation until 2050 and Prospects for the Period until 2100, as well as its updated 2022 version. It should be noted that the role of fast reactors in the energy system may vary depending on the goals and objectives set in terms of the fuel supply and adopted approach to spent fuel and waste management. The article examines various prerequisites that influence the parameters of fast reactors, taking into account these factors in the context of strategic planning along with the latest computational and analytical studies.
