Calculation of the Reactivity due to Bubble Collapse with the Probability Table Method

In this paper, the probability table method, originally developed for unresolved resonance calculations, is adapted to the calculation of bubble worths in a reactor core. Unlike previous approaches to this problem, this method is applicable to a broad class of problems, avoids a high variance Monte Carlo calculation, and preserves the main features of a random bubble distribution. This approach is illustrated by the solution to several problems of varying degrees of complexity.
