Traversing in core power monitoring system and method for monitoring the driving torque

摘要

A traveling reactor power monitoring system (1) includes a drive control unit (2) configured to drive a motor (4) and move a traveling probe (8) in a guide tube (24) by driving the motor (4), a torque sensor (5) configured to measure a drive torque of the motor (4), and a drive torque monitoring unit (11) that generates an alarm when the measured drive torque exceeds a predefined upper threshold, and that bypasses generating the alarm for a predefined bypass time, the predefined bypass time starting at a time of starting driving the motor (4).
