Method and program for complex calculation of heterogeneous reactor
Description
An algorithm and the GITA program for complex one-dimensional calculation of a heterogeneous reactor which permits to conduct calculations for the reactor and its cell simultaneously using the same algorithm are described. Multigroup macrocross sections for reactor zones in the thermal energy range are determined according to the technique for calculating a cell with complicate structure and then the continuous multi group calculation of the reactor in the thermal energy range and in the range of neutron thermalization is made. The kinetic equation is solved using the Pi- and DSn- approximations

Dans ce rapport on decrit le mode et les programmes (GITA) d'un calcul complexe d'un reacteur heterogene unidimensionnel, permettant d'effectuer le calcul de la cellule et du reacteur dans un seul algorithme. Les macrosections multigroupe de coeur d'un reacteur, dans le domaine des energies thermiques, sont determinees conformement au mode de calcul d'une cellule de structure complexe, apres quoi on effectue le calcul multigroupe de part en part du reacteur, dans le domaine du ralentissement et de la thermalisation des neutrons. L'equation cinetique est resolue en appliquant les approches Pi- et DSn-Files
