Safety Analysis of a Class 3 Component by ANSYS

This paper is a report for the safety analysis aimed at assessing the reliability and integrity of pressure retain in g boundary of essential service water pump with complicated geometry using finite element method The static analysis is investigated under five service loadings including the loads from OBE ( op e rat ion basis earthquake) and SSE (safety shut down earthquake) [1]. The n at u r al frequencies an d m o d al shapes of t h e p u m p are computed t o check if t h e static equivalent load m e t h o d can b e used for t h e seismic analysis addressed in the future work. In addition, the stress analysis for the accessories of the pump, namely flanges and bolts, are also shown in the paper
