ion of normal operation, including the effects of anticipated operational occurrences. GDC 10 is applicable to this section because the reviewer evaluates the effects and consequences of a control rod misoperation due to system malfunction or operator error for a BWR or a PWR to ensure that specified acceptable fuel design limits are not exceeded during normal operation, including the effects of AOOs. This SRP section and SRP Sections 4.2, 4.3, 4.4, 7.2, 7.7, 15.4.1, and 15.4.2 provide guidance for ensuring that instrument setpoints are initially within and remain within the technical specification limits, thereby ensuring that specified acceptable fuel design limits are not exceeded. DRAFT Rev. 3 - April 1996 15.4.3-4 Meeting the requirements of GDC 10 provides assurance that specified acceptable fuel design limits are not exceeded during either normal operations or AOOs (e.g., control rod misoperation) due to system malfunction or operator error.21 2. Compliance with GDC 20 requires that each reactor protection system be designed (1) to initiate the automatic operation of appropriate systems, including the reactivity control systems, thereby ensuring that specified acceptable fuel design limits are not exceeded as a result of anticipated operational occurrences, and (2) to sense accident conditions and to initiate the operation of systems and components important to safety. GDC 20 is applicable to this section because the reviewer evaluates the effects and consequences of a control rod misoperation due to system malfunction or operator error for a PWR or a BWR to ensure that acceptable fuel design limits are not exceeded as a result of AOOs. The reactor protection system automatically initiates the operation of appropriate systems, including the reactivity control system (RCS), to terminate the AOOs analyzed in this SRP section. AOOs such as those caused by a control rod misoperation are terminated in a timely manner so that acceptable specified fuel design limits
