ed Impact 1324 Revised identification of the system based upon terminology used in SRP Section 9.2.1 to describe this system. Also deleted reference to the listed system since the "Emergency Equipment Service Water System" nomenclature appears to be used far less frequently that other nomenclatures (e.g., "Emergency Service Water System") to describe this BWR system. 65. Integrated Impacts 1 and 1324 Added identification of the ultimate heat sink as important to safety. SRP Section 9.2.5 provides findings that the ultimate heat sink and its supporting systems meet Quality Group C requirements. Also added reference to a footnote indicating the existence of supplemental information for quality group classification of these systems in Appendix C. 66. Integrated Impact 1 Added reference to a footnote indicating the existence of supplemental information for quality group classification of this system in Appendix C. 67. No Change, see Potential Impacts In the ABWR and CE System 80+ FSERs, the staff 25499 and 25522 evaluated the safety classification of HVAC systems (or quality group classifications of associated cooling water systems) which do not appear to be covered by the existing nomenclature describing HVAC systems considered to be fluid systems important to safety in SRP Section 3.2.2. As an example, the safety classification of a system providing component cooling water equipment room (not an ESF equipment room) HVAC was evaluated by the staff in the CE System 80+ FSER. For lack of better terminology to describe the HVAC systems which are considered by the staff to be fluid systems important to safety, however, no change is proposed. The SRP-UDP has addressed the cooling/chilled water systems important to safety separately in other changes under this SRP Section draft revision.
