Abstract
A frequency measuring device measures a natural frequency of a reactor jet pump sensing line supported by a sensing line support bracket in a nuclear reactor. The frequency measuring device includes a base member, a sensing line clamp attached to the base member that attaches to the sensing line support bracket, and at least one actuator attached to the base member. The actuator is positioned relative to the sensing line when the sensing line clamp is attached to the sensing line so that the actuator can strike the sensing line. A proximity probe attached to the base member measures vibration of the sensing line and outputs a vibration signal. A processor receives and processes the vibration signal from the proximity probe to determine the natural frequency.
