Filed: 2006-12-28
Abstract: A method of determining an operation margin for a nuclear reactor is provided to enhance the operation efficiency of the nuclear reactor by preventing a fuel efficiency of a power station from being degraded. During a current operation period, power station operation data is accessed(210). A nuclear reactor is simulated by using the power station operation data, such that a simulation result having estimated dependent variable data is obtained(220). The estimated dependent variable data is normalized(230), such that normalized history dependent variable data is obtained. A time-based mean bias value with respect to the estimated dependent variable data is determined(240) by using the normalized history dependent variable data. A time-based uncertainty value of the estimated dependent variable data is determined by using the normalized history dependent variable data(250). Odds of a predetermined event and an allowable error level are obtained(260). Operation margins with respect to the allowable error level are calculated(270) based on the time-based mean bias value and the time-based uncertainty value.
