Abstract
Systems and methods of monitoring rod control systems of nuclear power plants, including: measuring a particular signal applied to at least one coil of a rod movement mechanism at one or more predetermined times relative to an initial energizing of a mechanism coil; comparing the measured signal to a reference signal parameter, and determining if the measured signal deviates from the reference signal parameter by a predetermined amount to indicate degradation of the rod control system.
Claims11
A method of monitoring a rod control system of a nuclear power plant, comprising:
- measuring an input to and/or output signal from at least one coil of a rod movement mechanism at one or more predetermined times relative to an initial energizing of a mechanism coil;
- calculating a signal parameter from the measured signal and comparing the measured signal to a reference signal parameter;
- and
- determining if the calculated parameter deviates from the reference signal parameter by a predetermined amount to indicate impairment of the rod control system.
A system to monitor rod movement signals of a rod control system of a nuclear power plant, comprising:
- a system to measure one or more signals applied to at least one coil of a rod movement mechanism;
- and
- a controller to acquire a measured signal at one or more predetermined times relative to energizing of a mechanism coil, to compare the measured signal to a reference signal parameter, and to determine if the measured signal deviates from the reference signal parameter by a predetermined amount to indicate impairment of the rod control system.
