The analysis of the ensuring reliable power supply of the auxiliary systems of the nuclear power plant (NPP) under emergency loss of the electrical communication with the power grid has been performed. The approach and fuzzy mathematical model for the risk failure assessment of the power supply of the auxiliary systems of the power plant from the external power grid have been proposed.

Key words: reliability, auxiliary, fuzzy sets, failures, power plant.
