A CEDM data acquisition system (40) receives analog coil-current signals from control element drive mechanism coils (18, 20); conditions the analog signals to remove noise induced therein by the electronic circuitry (44) associated with the control element drive mechanisms; digitizes the conditioned analog signals; displays the acquired test data; and records the data for future use. The inventive data acquisition system preferably has the ability to simultaneously measure, display and record coil-current data for all of the five coils associated with each CEDM rod-group with respect to time. Further, the inventive data acquisition system preferably allows the user to monitor, display and record data for up to eight CEDMs simultaneously. It also allows the measurement of rod-drop times during rod-drop testing of the CEDMs.
A data acquisition system for recording data associated with movement of at least one control element assembly through the nuclear reactor core of a nuclear steam supply system of the type having a plurality of control element drive mechanisms engaging a respective plurality of control element assembly shafts, each drive mechanism including a plurality of electrical coils which are powered by an electrical circuit to deliver coil-current whereby operation of the electrical circuit generates high frequency noise, said data acquisition system comprising:
