Abstract

Abstract

If the idling inertia of the nuclear main pump is designed too small, nuclear accident will be caused once the whole plant power failure occurs, and if the idling inertia is designed too large, the unit efficiency will be greatly reduced. Therefore, the accuracy of the idling calculation model is very important to ensure the safety of nuclear power plant and improve the unit efficiency. In this paper, the influence of coolant kinetic energy in the pipeline on the idling process of reactor coolant pump is considered. Through the power conservation equation and pump similarity law during start-up and shutdown, the idling transient calculation model considering the influence of pipeline coolant is deduced and established, and the simple calculation formulas of idling inertia and idling time of pump unit are given, which makes the calculation results more accurate and has a wider range of engineering application, and can be applied to the accurate design of idling inertia and the accurate calculation of idling time in nuclear and non-nuclear engineering.
