  • Subcritical core reactivity bias projection technique
    Patent number: 11393599
    Abstract: A method to determine a global core reactivity bias and the corresponding estimated critical conditions of a nuclear reactor core prior to achieving reactor criticality. The method first requires collection and evaluation of the inverse count rate ratio (ICRR) data; specifically, fitting measured ICRR vs. predicted ICRR data. The global core reactivity bias is then determined as the amount of uniform reactivity adjustment to the prediction that produces an ideal comparison between the measurement and the prediction.
    Type: Grant

    Date of Patent: July 19, 2022
    Assignee: Westinghouse Electric Company LLC
