Abstract

Abstract

Traditional equipment grading method is based on the realization of safety function, which can not take into account the economy of nuclear power plant (NPP). A new method of equipment grading based on the system reliability allocation and system importance and nuclear safety importance factor is proposed for solving this problem and achieving high safety and high economy of NPP. Taking the condensate water supply system of floating nuclear power plant as an example, the equipment reliability grading research is carried out. The quantitative results of reliability considering system importance and nuclear safety importance are given. The results can be used as the basis for equipment grading, and can be used for maintenance, fault diagnosis and health management of power plant equipment.
