luding loss-of-coolant accidents. These structures, systems, and components shall be appropriately protected against dynami.c effects, including.the effects of missiles, pipe whipping, and discharging fluids that may result.from equipment failures and from events and conditions outside the nuclear power unit.'" Applicability: All instrumentation and control systems and components important to safety. Review..Methods: The environmental and missile design bases for instrumentation and control 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 which are qualified to accommodate the effects of environmental conditions and protected for dynamic effects of missiles, pipe whipping, and discharging fluids. If systems or components are qualified to survive the environmental effects'of postulated accidents for only finite periods of time, the bases for limited operability should be provided. The review should confirm that the instru- ment and control systems important to safety are qualified to be compatible with the environmental effects of accidents consistent with the'analysis of these events as provided in Chapter 15 and with the effects of missiles as provided in Chapter 3 of the SAR. The evaluation of the adequacy of qualification programs to' demonstrate the capability of instrumentation and control systems to accommodate the environmental effects'of postulated accidents and missiles is' addressed in the review of Section 3.11 of the SAR. 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' includ- ing those variables and systems that can affect the fission process, the integrity of the teictor cbre, the.reactor coolant pressure
