ns and methods, and margin in the I&C design. The reactor systems and I&C reviewers should work together to understand the margins provided in the applicant's design and to confirm there is reasonable assurance that adequate margin is provided. (e) GDC 13, "Instrumentation and Control" "Instrumentation shall be provided to monitor variables and systems over their anticipated ranges for normal operation, for anticipated operational occurrences, and for accident conditions as appropriate to assure adequate safety, including those variables and systems that can affect the fission process, the integrity of the reactor core, the reactor coolant pressure boundary, and the containment and its associated systems. Appropriate controls shall be provided to maintain these variables and systems within prescribed operating ranges." Applicability - All I&C systems including supporting data communication systems. Review Methods - Review of compliance with GDC 13 should include consideration of the following topics. • Instrumentation to monitor plant variables and systems - See SRP Sections 7.5 and 7.7. • Instrumentation to monitor the status of protection systems - See SRP Appendix 7.1-B Subsections 4.9, 4.13, 4.19, or SRP Appendix 7.1-C Subsections 5.8 and 6.5. • I&C for manual initiation of safety functions - See SRP Appendix 7.1-B Subsections 4.17 and 4.19, or SRP Appendix 7.1-C Subsections 5.8, 6.2, and 7.2. • I&C to support diverse actuation of safety functions - See SRP Section 7.8. • I&C to regulate ESF systems - See SRP Section 7.3. • Interlocks to maintain variables and systems within safe states - See SRP Section 7.6. • I&C to maintain variables and systems within normal operational limits - See SRP Section 7.7. • Protection of instrument sensing lines from environmental extremes - See Regulatory Guide 1.151, "Instrument Sensing Lines." • Setpoints for instrumentation system alarms and control system actions - See SRP BTP 7-12. • Data communication
