Abstract

Nearly all models concerned with the reliability of redundant systems assume that a failed component does not affect the other working components. This assumption does not apply to many nuclear power systems. In this paper, a high voltage (HV) system consisting of a power supply and two transmitters is considered. We treat the more realistic case of stochastic dependence in the sense that, caused by the failure of a component (transmitter), the failure rate of the working component increases. A model of the HV system as well as a detailed development of the reliability function of this system are presented. The mean time to failure of the HV system is also obtained. A numerical example is provided to illustrate the results.
