munication systems. Review Methods — The environmental and missile design bases for I&C systems important to safety should be provided for each system in subsequent sections of Chapter 7 of the SAR. The design bases should identify those systems and components that are qualified to accommodate the effects of environmental conditions and protected from dynamic effects of missiles, pipe whipping, and discharging fluids. If systems or components are qualified to survive the environmental effects of postulated accidents for limited periods of time, the bases for limited operability should be provided. Review of equipment qualification for environmental conditions should be conducted in accordance with the guidance provided in Appendix 7.1-B item 5 and Appendix 7.1-C item 9. The instrumentation systems needed for severe accidents must be designed so there is reasonable assurance that they will operate in the severe-accident environment for which they are intended and over the time span for which they are needed. They need not be subject to additional environmental qualification requirements. Rev. 4 — June 1997 SRP 7.1-A-13 The review of this requirement should be coordinated with EELB. d. Criterion 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 and supporting data communication systems. Review Methods — Review of compliance with GDC 13 should include consideration of the following topics. • Instrumentation
