Influence of nuclear data representation accuracy on the results of neutron transport simulation
P. M. Nikulin

This work is devoted to studying of the influence of the nuclear data representation accuracy on the results of neutron transport simulation using the TDMCC code based on Monte Carlo method. The transition from the evaluated nuclear data, usually stored in a file format ENDF-6, to the nuclear data, used directly in the program TDMCC, includes a number of changes that may affect the results of calculations. 
This study is important, both for the further development of nuclear data used by the program TDMCC, and for the successful use of the program to address the problems of nuclear and radiation safety. In carrying out the work it was developed a software package with which were formed a new, more accurate nuclear data library for the program TDMCC. Subsequent simulations showed that an increase in the accuracy of the angular distributions leads to a difference in the results of the simulation. The paper presents the results of this study.
