Description
In this paper calculations of fast neutron penetration through Fe and Pb as shielding materials is performed. The efficiency of combined method of the invariant imbedding and transfer matrix is treated. Transmitted and reflected fluxes for different shielding thicknesses for the case of the neutrons with distorted fission spectrum as well as for the plane source of unit intensity are obtained. Comparison of the result with the data from literature shows satisfactory accuracy of the applied method as well as shortening of the computer time, even for the larger shielding thicknesses (author)

Obavljeno je vise proracuna prolaza brzih neutrona kroz zastitne ploce od gvozdja i olova. Testirana je efikasnost kombinovane metode invarijantnog ulaganja i transfernih matrica. U slucajevima upadnih neutrona sa izmenjivim fisionim spektrom, kao i za monoenergetski izotropni ravni izvor jedinicnog intenziteta, dobijeni su transmitovani i reflektovani fluksevi neutrona pri razlicitim debljinama zastite. Poredjenje rezultata sa podacima iz literature pokazuje zadovoljavajucu tacnost primenjene metode i mali utrosak vremena na racunaru, cak i za vece dimezije zastite (author)Files
