Análisis tecnoeconómico de un sistema de generación de energía con reactores nucleares tipo SMR en Colombia

Abstract

In this study presents a techno-economic analysis of the design of a power generation system based on a 500 MWth High-Temperature Gas-cooled Reactor (HTGR) Small Modular Reactor (SMR), using the HTR-PM project in Shidaowan, China, as a reference. The proposed system operates with a Brayton-Rankine combined cycle, utilizing a helium gas turbine, achieving a thermal efficiency of 41 % and a second-law efficiency of 59 %, resulting in a net power output of 206.8 MWe. In addition to the technical analysis, an economic study was conducted based on cost estimates from the Idaho National Laboratory (INL), allowing the calculation of CAPEX, OPEX, and the Net Present Value (NPV) for Colombia. Inflation adjustment techniques and localization factors were applied, obtaining an inflation-adjusted Levelized Cost of Electricity (LCOE) of 278.687 (With inflation) USD/MW-h. These values were compared with the LCOE of alternative generation technologies in Non Interconnected Zones (ZNI), as reported by the UPME, demonstrating a competitive advantage over some of these technologies due to its capacity and high plant factor of 92.75 %.
