The influence of the form of the cells on the buckling and fine structure of the thermal flux in a heterogeneous pile; Influence de la forme des cellules sur le laplacien et structure fine du flux thermique dans une pile heterogene

Abstract

The elementary diffusion equation and the age equation have been solved for lattices assumed, to be infinite and periodic. In this way the influence of the form of the cells on thermal captures and resonance captures is determined. The solutions obtained are expressed by means of tabulated functions which can be used in the analysis of the f factor measurements. The case of mixed lattices in which different types of rods are regularly arranged is also foreseen. (author) [French] L'equation elementaire de la diffusion et l'equation de l'age ont ete resolues pour des reseaux supposes infinis et periodiques. On determine ainsi quelle est l'influence de la forme des cellules sur les captures thermiques et les captures de resonances. Les solutions obtenues s'expriment au moyen de fonctions tabulees qui peuvent etre utilisees dans le depouillement des mesures du facteur f. Le cas des reseaux mixtes dans lequels des barreaux de types differents sont disposes regulierement est egalement envisage. (auteur)
