부유식 SMR 온배수를 열원으로 하는 온도차발전 사이클의 성능비교 = Performance Comparison of ORC Cycles Using Floating SMR Warm Water as a Heat Source

다국어 초록 (Multilingual Abstract)

According to an IEA report, AI data center power consumption is projected to reach 945 TWh by 2030, more than double the 2024 data center power consumption. Consequently, numerous studies are underway to explore the practical application of Small Modular Reactors (SMR) to meet this rapidly increasing power demand. This study investigated Organic Rankine Cycle (ORC) using cooling discharge water from the power conversion system of a floating offshore SMR as the heat source and additional deep sea water intake as the heat sink. Performance comparisons were conducted for six working fluids.
Comparing turbine gross power, pump power consumption and net power output revealed that R32 achieved a net power output of 302.5 kW. This confirmed that ORC using SMR cooling drainage could offset the power consumption of the SMR power conversion system's cooling seawater pump, the deep water pump for the ORC and the working fluid pump, while also generating additional power.
