To the Point of Forecasting of Reliability and Resource of Steam Generator Pipe System of Nuclear Power Plant with <i>VVER</i>
The mathematical model is offered in this work, which allow to forecast the time of taking away from using the steam generators of NPP with VVER. The prognosis is based on the using the equation of Kolmogorov, on the basis of which the dependences of a medium number of closed heat exchanging pipes and the dispersion of distribution in the time function, were founded in an analytical form
