Abstract

Abstract

In order to obtain the design parameters that have a greater impact on the dynamic response of the reactor coolant system, shorten the design cycle, and improve the design efficiency, this paper uses the support stiffness and support clearance of the steam generator (SG) in the reactor coolant system (RCS) as input variables, and uses OPTIMUS integration platform to carry out the sensitivity analysis of the system dynamic response to the input variables under seismic conditions. The analysis shows that the bending moment of the inlet nozzle of the main pump is more sensitive to the clearance of the lower horizontal support of SG. The relevant sensitivity analysis method and analysis process can be extended to other systems and equipment of nuclear power plant, providing quantitative analysis means and data support for reliability analysis parameter selection and optimization design improvement of reactor coolant system.
