CRDM METHOD AND SYSTEM FOR MONITORING CONTROL ROD DRIVECRDM

摘要

The present invention relates to a method for monitoring the overall driving state of a control rod drive system (CRDM), and a system for the same. Specifically, it is possible to detect abnormalities in the control rod driving device in advance by judging whether the control rod driving device shows an abnormal driving state due to foreign substances, etc. based on the information obtained by the coil current sensor and the vibration sensor, or This is to make it easier to understand the anomaly.
