w controller malfunction causing an increase in BWR core flow rate. This section, SRP Sections 4.2 through 4.4, and 7.2 through 7.5, and Regulatory Guides 1.53 and 1.105, provide guidance for ensuring that the reactor core, coolant, control and protection systems are designed with appropriate margin. Meeting the requirements of GDC 10 provides assurance that SAFDLs are not exceeded during any condition of normal operation, including the effects of AOOs. 2. GDC 13 requires the provision of instrumentation that is capable of monitoring variables and systems over their anticipated ranges to assure adequate safety, and of controls that can maintain these variables and systems within prescribed operating ranges. GDC 13 applies to this section because the reviewer evaluates the sequences of events, including automatic actuations or protection systems, and manual actions, and determines whether the sequence of events is justified, based upon the expected values of the relevant monitored parameters and instrument indications. 3. Compliance with GDC 15 requires that the reactor coolant system and associated auxiliary, control and protection systems be designed with sufficient margin to ensure
