Popis:	Algorithms for evaluating the systematic error of Monte Carlo calculations performed using different variants of an approximate solution of a homogeneous neutron transport equation (the method of a constant number of points of division and augmentation, and others), when the number of neutrons per generation is reduced to a number set a priori, are described. A relation for evaluating this error on multiprocessor computers is proposed. The computational results obtained for the systematic error by means of the theoretical relation and experimentally for a full-scale three-dimensional model of a VVER-1000 core are presented. Recommendations for choosing the number of particles per generation which gives an acceptably low error are made.
