Abstract

Abstract

We analyzed and simulated the throttling orifice RCV001/002/003 DI of M310 NPP’s RCV System. The defect in the original design of M310 has been found and optimized by using the step-orifice to reduce vibration and noise. This design change has been applied and verified by several NPPs which are either under construction or operation.
- RCV,
- Throttling orifice,
- Cavitation
