Abstract

The equipment component and system structure of Loose Part Monitoring System（LPMS） in Tianwan NPP are introduced, and the alarm logic of LPMS is described. According to years operation record of LPMS in Tianwan NPP, the typical cases of false alarm of LPMS are analyzed and diagnozed, and the signal characteristics and origin of loose part alarm are summarized.
- Loose Part Mouitoring System（LPMS）,
- Nuclear power plant,
- Diagnose
