Summary

The article represents a methodology of neutron flux density absolute values determining by countability in impulse channels of nominal nuclear safety control system of "Ukryttya". The procedure for calculating takes into account the dependence of detector sensitivity on rigidity of the neutron energy spectrum (movement with stiffness) at each control point. Also there is a substantiation of the quantitative values of warning and alarm setpoints of security, which are determined by current and annual average values of the neutron flux density.

Keywords: measuring channel,  the neutron flux density, methodology, setpoints of security, the "Ukryttya" object.
