Abstract:
We consider the problem of processing statistical data obtained during the operation of pumping units CN 60-180 operating as standard equipment of the VVER-1000 reactors. Data for analysis was taken from the industry database of VNIIAES. The objects' operation has been observed from January 1, 1990 to December 31, 2007. Statistical information is processed with nonparametric estimation method called root estimation. We obtain reliability characteristics for the units: time-to-failure density and distribution function, faultless operation probability, and fault intensity. The obtained results are used to determine control influences.
