The reactivity due to the collapse of a large number of small bubbles in a reactor core has been analyzed with Behrens' method, Benoist's method, and the probability table method. Each analysis has used a different stochastic model for the bubble distribution within the reactor core: the Nicholson--Goldsmith calculations have employed a closely-spaced holes model; the Gelbard--Lell calculations have employed a random cube model; the Hoffman--Petrie calculations have employed a nuclear model. However, any of the models can be used with any of the methods. In this paper, the three void models are evaluated. Based on this analysis, the closely-spaced …

Description
The reactivity due to the collapse of a large number of small bubbles in a reactor core has been analyzed with Behrens' method, Benoist's method, and the probability table method. Each analysis has used a different stochastic model for the bubble distribution within the reactor core: the Nicholson--Goldsmith calculations have employed a closely-spaced holes model; the Gelbard--Lell calculations have employed a random cube model; the Hoffman--Petrie calculations have employed a nuclear model. However, any of the models can be used with any of the methods. In this paper, the three void models are evaluated. Based on this analysis, the closely-spaced holes model is recommended as the most suitable for analysis of bubble collapse in a molten, LMFBR core.
