ECONOMIC EFFICIENCY AND POSSIBILITIES OF USING MEGAWATT-CLASS NUCLEAR POWER SOURCES IN THE ARCTIC

Advanced adaptation of electric-power technologies to the specifics of self-contained power supply is one of the basic factors for complex socio-economic development of the Russian Arctic zone. With a decrease in the size of the territory under consideration the role of electric power industry in inter-branch relations is growing, and thus reliable electric power supply to existing and prospective consumers of the Arctic region becomes crucially important. The possibility of using megawatt-class Nuclear Power Sources (NPS) is discussed. Groups of prospective consumers with a power range up to several MW are distinguished. Features of the NPS life cycle based on maximum self-sufficiency in construction, operation, decommissioning, and spent fuel management are described. A list of technical and managerial issues when finalizing the system of megawatt-class NPS is provided. Economic models of using megawatt-class NPS and estimates of their relative competitive ability (the LCOE and integration costs methods) have been developed. Parameters of economic efficiency of megawatt-class NPS are provided.
