Abstract: The influence of model parameters for the subcritical assembly core of the subcritical nuclear facility "Neutron Source" and uncertainties of nuclear reaction cross sections on the values of the effective neutron multiplication factor is investigated. The analysis is based on numerical simulation using the international software code MCNP 6.2. The possibility of achieving the design nuclear fuel load of 38 fuel assemblies for the subcritical assembly core with the tungsten neutron-generating target is shown with the justification of nuclear safety.

Keywords: effective neutron multiplying factor, subcritical assembly, nuclear safety, subcritical nuclear facility.
