A proposal for the calculation of the critical buckling of a PWR or undermoderated lattice

Creators

Description

A method improving the calculation of the critical buckling of a PWR or undermorated lattice is proposed. This method takes into account the lattice heterogeneity with more detail than the existing ones; it lies on some approximations. The method requires a relatively small inplementational effort. It could be used in the calculation of fast reactors

Abstract (French)

On propose une methode permettant d'ameliorer le calcul du laplacien critique d'un reseau de REP ou de RSM, en tenant compte de maniere plus detaillee de l'heterogeneite du reseau. Cette methode, qui repose sur quelques approximations, pourrait etre mise en oeuvre dans un delai relativement bref. Elle pourrait egalement etre utilisee dans le calcul des reacteurs a neutrons rapides
