Abstract : The decision to use isotope ratios must be based on a good understanding of their behavior as it is related to the safeguards function. It is especially important to understand how to define isotopic ratios which have the highest degree of constancy over prescribed ranges of reactor perturbations and exposure. The reliance to be placed on isotopic ratios must be assessed with the help of theory by determining whether there is a methodology based on theory that will produce isotopic ratios with the desired characteristics in future applications. The purpose of the paper is to present some insights into the constancy of certain isotopic ratios with potential safeguards applications, and also to present some methods of making isotopic ratios more accurate and foolproof in safeguards applications.
