Abstract

The transport of monoenergetic neutrons in spherical geometry with forward scattering and vacuum boundary conditions is considered. The scaled transport equation is solved using the Fn method by considering the pseudo-slab problem. Numerical results for the fundamental and higher order eigenvalues are presented for several significant figures. Some selected results are compared with those obtained using various methods in the literature. Finally, a few remarks about the behavior of the criticality eigenvalue of the neutron transport equation with forward scattering is given.

Abstract

Untersucht wird der Transport monoenergetischer Neutronen in sphärischer Geometrie. Die Transportgleichung wird mit Hilfe der FN-Methode gelöst. Numerische Ergebnisse für die Eigenwerte höherer Ordnung werden vorgestellt für einige wichtige Fälle. Ausgewöhlte Ergebnisse werden verglichen mit Ergebnissen aus der Literatur, die mit verschiedenen anderen Methoden erhalten wurden. Den Abschluss bilden einige Bemerkungen zum Verhalten des Eigenwertes der Kritikalität der Neutronentransportgleichung mit Vorwärtsstreuung.
