About economic competitiveness of Small Modular Reactor with accident tolerant fuel. Part 1

DOI: 10.33917/mic-4.123.2025.62-69

The method of analytical calculation of the microeconomic criteria of investment efficiency into PWR Small Modular Reactor is presented as depending on the engineering, physical and economic parameters of the reactor. This method is convenient for multi-variant preliminary searches of acceptable criteria for SMR competitiveness. As a prototype SMR reactor is being considered RITM-200N with a period of 6 years of continuous work (before fuel overload) and the use of tolerant fuels, accident-resistant, consisting of metal ceramic composition in a chromium-nickel alloy shell (42XHM). The results of calculations of the relationship between engineering and physical parameters of the reactor, electricity costs and the payback period for investments are given.
