Content:
As discussed before, the level of detail in any particular Design description, Figure, or ITAAC should be proportional to the safety significance of the SSC being reviewed. Therefore, all items shown on the check lists will not be applicable to all systems being reviewed. 14.3-49 DRAFT Rev. 0 - April 1996 DESIGN DESCRIPTION CHECK LIST SYSTEM: 1. System purpose/functions (minimum is safety functions, may include some non-safety functions) 2. Location of system (containment, reactor building, etc.) 3. Key design features of the system (such as ADS part of SRVs, flow limiters, backflow protection, surge tanks, severe accident features, etc.) 4. Seismic and ASME code classifications 5. System operation 6. Controls/displays 7. Logic 8. Interlocks 9. Class 1E electrical power sources/divisions 10. Equipment to be qualified for harsh environments 11. Interface requirements (See Appendix C.I for guidance.) DRAFT Rev. 0 - April 1996 14.3-50 FIGURES CHECK LIST SYSTEM: 1. All components discussed in the design description. 2. Boundaries with interfacing systems should be clearly delineated in the figures/diagrams. 3. ASME code class boundaries for mechanical equipment and piping. 4. As a minimum, instruments required to perform Generic Technical Guidelines (e.g., ERGs, EPGs)(as described in the DCD Tier 2 Chapter 18). 5. Essential alarms that are not included in the minimum inventory of alarms. 6. Class 1E power sources (i.e., division identification) for electrical equipment. 7. Identification of all alarms, displays, and controls on the remote shutdown panel unless these are covered by the remote shutdown panel ITAAC. 8. Pneumatic- and motor-operated valves and check valves that perform "active" safety functions, including all POVs/MOVs that are within the scope of GL 89-10. 9. Fail-safe position of pneumatic valves that are relied upon to accomplish the direct safety function of the system. (See Appendix C.I for guidance.) 14.3-51 DRAFT Rev. 0 - April 1996 ITAAC CHECK LIST
