Abstract :
The paper discusses the assessment of a typical quadruple modular redundant nuclear protection system, DIPS. This assessment proved difficult for several reasons, including: complex fault-tolerant architecture, multistate components, large number of components, and because some approximations were necessary to compute DIPS unavailability with a method using standard dependability tools. The authors present the results of the study in terms of the average DIPS down time over a one-year period.
