that address systems that implement those features. SRP Section 7.5, “Information Systems Important to Safety,” provides the review criteria for the information systems important to safety, which includes instrumentation that indicates the need for manual initiation and control of ESF systems. Examples of ESF systems, Auxiliary Supporting Features and Other Auxiliary Features are as follows: Typical ESF systems are: A. Containment and reactor vessel isolation systems B. Emergency core cooling systems C. Containment heat removal and depressurization systems D. Pressurized water reactor auxiliary feedwater systems E. Emergency boration systems F. Boiling water reactor standby gas treatment systems G. Containment air purification and cleanup systems H. Containment combustible gas control systems I. Control room isolation and emergency heating, ventilating, and air conditioning (HVAC) Typical auxiliary supporting features and other auxiliary features (additional information is provided in Appendix 7.1-C) are: A. Electric power systems B. Diesel generator fuel storage and transfer systems C. Instrument air systems D. HVAC systems for ESF areas 7.3-3 Draft Revision 6 – August 2015 E. Essential service water and component cooling water systems Figure 3, “Examples of Equipment Fitted to Safety Systems Scope Diagram,” of the Institute of Electrical and Electronics Engineers (IEEE) Standard (Std) 603-1991, “IEEE Standard Criteria for Safety Systems for Nuclear Power Generating Stations,” provides a matrix with an extensive list of auxiliary supporting features and other auxiliary features. 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
