Key Regulatory Issues for Digital Instrumentation and Control Systems at Nuclear Power Plants
To help reduce the uncertainty associated with application of digital instrumentation and controls (I&C) technology in nuclear power plants, the Nuclear Regulatory Commission (NRC) has issued six Interim Staff Guidance (ISG) documents that address the current regulatory positions on what are considered the significant digital I&C issues. These six documents address the following topics: Cyber Security, Diversity and Defense-in-Depth, Risk Informed Digital I&C Regulation, Communication Issues, Human Factors, and the Digital I&C Licensing Process (currently issued as Draft). After allowing for further refinement based on additional technical insight gathered by NRC staff through near-term research and detailed review of relevant experience, it is expected that updated positions ultimately will be incorporated into regulatory guides and staff review procedures. This paper presents an overview of the guidance provided by the NRC-issued ISGs on key technology considerations (i. e., the first five documents above) for safety-related digital I&C systems.
