s important to safety that provide information to the operator for the manual control of systems required for safe shutdown. Section 9.5.1.1, “Fire Protection Program,” of the SRP includes the I&C provided as part of an alternative or dedicated shutdown capability needed for compliance with GDC 3, “Fire Protection.” Typical functions required for safe shutdown are: • Reactivity control • Reactor coolant makeup • Reactor pressure control • Decay heat removal • Suppression Pool Cooling (BWR) Typical auxiliary supporting features and other auxiliary features (additional information is provided in SRP Appendix 7.1-C, “Guidance for Evaluation of Conformance to IEEE Std 603”) are: 7.4-3 Revision 6 – August 2016 • Electric power systems • Component cooling water • Service water • Instrument air systems 2. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant's proposed ITAAC associated with the structures, systems, and components (SSCs) related to this SRP section in accordance with SRP Section 14.3, "Inspections, Tests, Analyses, and Acceptance Criteria." The staff recognizes that the review of ITAAC cannot be completed until after the rest of this portion of the application has been reviewed against acceptance criteria contained in this SRP section. Furthermore, the staff reviews the ITAAC to ensure that all SSCs in this area of review are identified and addressed as appropriate in accordance with SRP Section 14.3. 3. COL Action Items and Certification Requirements and Restrictions. For a DC application, the review will also address COL action items and requirements and restrictions (e.g., interface requirements and site parameters). For a COL application referencing a DC, a COL applicant must address COL action items (referred to as COL license information in certain DCs) included in the referenced DC. Additionally, a COL applicant
