Abstract
The thermal efficiency of Super Critical Water Reactor (SCWR) nuclear power plant is studied here. It is affected by three feedwater regenerative parameters namely enthalpy rise distribution of heaters, corresponding optimum feedwater temperature and number of regenerative stage. These parameters are interlinked. The steam cycle system of SCWR contains two-stage reheating and eight-stage regenerative system. Average Distribution Method (ADM) is used to study the relationships between these parameters. Different thermal efficiency parameters of the circulating system in SCWR are calculated and optimized. The results can be a good reference for the design of steam circulation system in SCWR design. 280°C will be a proper temperature selected for the core inlet. Based on the investigation of existing supercritical steam turbine technology of the supercritical fossil power plant, some useful suggestions are given for the steam turbine design of SCWR.
