Abstract

Performing exhaustive model checking for a digital instrumentation and control (I&C) system, when both hardware failures and the detailed functionality of the I&C system are considered, can be challenging due to scalability issues. In our previous work, we have proposed a coupling approach where the model checking analysis is restricted to a limited set of postulated hardware failures based on probabilistic safety assessment (PSA) results, potentially improving scalability of model checking. Based on the pilot case study using a small example system, the coupling approach should scale quite well to larger systems. In this paper, we study the applicability of the coupling approach by performing a case study using a more complex example system, based on a fictitious reference model of a boiling water nuclear reactor. Compared to unrestricted model checking analysis, the computation times decreased considerably when the analysis was restricted. Still, the overall process for introducing the failures requires a lot of manual labor, and needs to be automated.
