Loose part monitoring system and vibration monitoring system(KIR)

Description
Loose part monitoring system (LPMS) and vibration monitoring system (VMS) for NPP reactors are designed to on-line monitor the loose and fallen parts possible existing in the Reactor Pressurized Vessel, Steam Generator and primary pump, and monitor the vibration of the Reactor Pressurized Vessel and Reactor internal periodically.

Characteristics
l False alarm problem for KIR system is avoided;
l On-line initial diagnosis function is provided;
l Off line diagnosis system and specialists supports are provided, and the technical service mode by “signal collection+ initial diagnosis+ specialists supports” is adopted.
