On the reliability of nuclear power plants

Using the theory of depleted restoration flows, the authors obtained the algorithm for the calculation of the maximum non-failing value of some parameter, which is a function of the time of existence of another parameter outside the permissible limits. They prove the theorem of the limit of this maximum value under conditions of an unlimited increase in statistics on failures of nuclear power plants (NPP). The proposed formalism makes it possible to establish, in the course of resource tests or during the operation of the NPP elements, the limit of serviceability of these elements during their operation beyond the permissible loads
