The economic estimation of nuclear power reactors is a prerequisite and basis for reactor technology selection. The basic economic and investment metrics are levelized cost of electricity (LCOE), net present value (NPV), internal rate of return (IRR) and return of investment (ROI). Those metrics have been evaluated for advanced reactors (conventional large reactors and small modular reactors) promising for construction in Ukraine: АР1000 Westinghouse and small modular reactors: VOYGR NuScale, SMR-160 Holtec, SMR Rolls-Royce. The estimated indicators have been compared with the renewable energy sources (solar and wind) with comparable electric capacity. Open data were used as a source, specifically IAEA ARIS database, vendor’s websites and national data on implementing renewable energy projects. Calculations were made using the IAEA NEST (Nuclear Energy System Economics Support Tool) toolkit. Specific factors influencing the technical and economic indicators of nuclear technologies were considered: maturity of the technology (FOAK/NOAK), new or existing site and localization of production. Sensitivity analysis to the key technical parameters of different energy sources and assumptions was performed.
