Abstract
Systems and methods of monitoring step movements of control rods of a nuclear power plant, including measuring output signals of a plurality of rod movement coils during a step movement sequence of one or more control rods, analyzing the output signals to determine a direction of the step movement sequence, and comparing one or more output signals to reference output sequence to verify that a step of the control rod has occurred.
Claims11
A method of monitoring step movements of control rods of a nuclear power plant, comprising:
- measuring output signals of a plurality of rod movement coils during a step movement sequence of one or more control rods;
- analyzing the output signals to verify the rod movement and determine a direction of the step movement sequence.
A step counter system for a rod control system of a nuclear power plant, comprising:
- a measuring unit to measure output signals of a plurality of rod movement coils during a step movement sequence of one or more control rods;
- and
- a controller to analyze the output signals to determine a direction of the step movement sequence, analyzing the output signals to verify the rod movement.
