Section: claims

1. A traveling reactor power monitoring system for moving a traveling probe connected to a probe cable in a guide tube, comprising:a drive control processor configured to drive the motor and move the traveling probe in the guide tube by driving a motor;a torque sensor configured to measure a drive torque of the motor; anda drive torque monitoring processor configured to generate an alarm when the measured drive torque exceeds a predefined upper threshold, and configured to bypass generating the alarm for a predefined bypass time, the predefined bypass time starting at a time of starting driving the motor,wherein:the drive control processor is configured to drive the motor at a higher speed when the traveling probe is at a first area in the guide tube and at a lower speed when the traveling probe is at a second area in the guide tube, andthe drive torque monitoring processor configured to bypass generating the alarm during switching between the higher speed driving and lower speed driving. 2. The traveling reactor power monitoring system of claim 1, wherein:the drive torque monitoring processor is configured to stop driving the motor when the drive torque exceeds the predefined upper threshold, and to bypass generating the alarm for the predefined bypass time when the chive control processor restarts driving the motor. 3. The traveling reactor power monitoring system of claim 1, wherein:the drive control processor is configured to drive the motor at the lower speed at a probe position that the chive torque is measured to exceed the upper threshold. 4. The traveling reactor power monitoring system of claim 1, wherein:the drive control processor is configured to store a position of the probe when the measured drive torque of the motor is measured as exceeding the predefined upper threshold; andthe drive control processor is configured to move the motor alternately in forward and reverse at the stored position of the probe that the measured drive torque exceeds the upper threshold.
