Abstract

In nuclear power plants, there is an accelerating trend to upgrade and replace analog instrumentation and control systems with digital systems. This transition from analog to digital I&C systems is due to their added capabilities and their potential to improve reliability and safety of the corresponding plants. As this replacement process continues, one or more methodologies to address digital I&C system reliability are needed to quantify the risk introduced into the plants by such systems. In reviewing the proposed methodologies, it has become apparent that there is no benchmark system available to be used as the basis for methodology comparison. A set of preliminary requirements for a benchmark system is presented to evaluate objectively methodologies available for the reliability modeling of digital I&C systems in nuclear power plants. These requirements will provide a basis for the future development of a benchmark system.
