<p>A system and method of testing in-core flux detectors that determines a n effective prompt fraction for an in-core flux detector based upon the dynami c response of the detector to a power change event within the reactor. Ion chamber detectors may provide a reference signal against which the in-core flux detector signals can be compared. The in-core flux detector response is analyzed over a time interval following the power change event that may be shorter than the time constant for the fastest delayed component of the detector response. The data acquisition system may include multiple subsystems that are isolated from one another through isolation barriers. In particular, a clock signal from one subsystem to another may pass through an isolation barrier.</p> |
