| description | Existing nuclear power generation facilities are currently seeking to replace obsolete analog Instrumentation and Control (I&C) systems with contemporary digital and processor based systems. However, as new technology is introduced into existing and new plants, it becomes vital to assess the impact of that technology on plant safety. From a regulatory point of view, the introduction or consideration of new digital I&C systems into nuclear power plants raises concerns regarding the possibility that the fielding of these I&C systems may introduce unknown or unanticipated failure modes. In this paper, we present a fault injection based safety assessment methodology that was applied to a commercial safety grade digital Reactor Protection System. Approximately 10,000 fault injections were applied to the system. This paper presents a overview of the research effort, lessons learned, and the results of the endeavor. |
