| Summary: | The Component Cooling System (CCS) and the Sea Water System (SWS) of HPR1000 are heat removal systems related to the safety of nuclear power plants. In both CCS and SWS, the configuration of pumps is closely associated with system design and energy consumption. This paper addresses the issue of high energy consumption and poor economic performance of the current configuration scheme that relies on a single large-capacity constant frequency pump. Based on a mathematical model for CCS and SWS that can be utilized for optimization calculations, we propose and validate an Improved Non-dominated Sorting Genetic Algorithm II (INSGA-II) with good algorithm performance, optimizing for system design costs and total operational costs as objectives, and provide a sensitivity analysis of relevant variables. The results demonstrate that compared to the prototype values of HPR1000, the investment costs of CCS and SWS can be reduced by up to 4.65 %, and the total operational costs can be decreased by as much as 63.6 %, with the optimization effect being most significant when variable frequency pumps are used in CCS and SWS. |
