A formalism is developed for full exploitation of a gas tag system used for locating failed fuel elements in fast reactors. Based on the measured gas tag ratios detected in an actual failure, the method assigns quantitative probabilities to the various combinations of failures which can occur. Both the failure of a single fuel element and the simultaneous failure of two elements are treated in detail.
