Abstract

Abstract

In order to ensure that the main coolant pump（RCP） meets the requirements of half flow time after reactor shutdown and power accident,the moment of inertia of the RCP,whether need to add the flywheel and the RCP rotor’s dynamic performance are analyzed in this paper.Demonstration of flywheel scheme and sensitivity analysis of bearing water film stiffness on the rotor dynamic characteristics are presented.
- RCP,
- Moment of inertia,
- Flywheel scheme,
- Rotor dynamic characteristics,
- Sensitivity analysis
