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. 48. Editorial In addition to changes identified by redline/strikeout, the list of systems was reordered alphabetically. 49. Integrated Impact 1 Added reference to a footnote indicating the existence of supplemental information for quality group classification of this system in Appendix C. 50. Integrated Impact 1 Added reference to a footnote indicating the existence of supplemental information for quality group classification of this system in Appendix C. 51. Editorial Revised for improved consistency with terminology used in SRP Section 9.2.6 to describe this system. Note that SRP Section 9.2.6 refers to this system as "Condensate Storage Facility (CSF)." Note also that the nomenclature "Condensate Storage and Transfer System" is commonly used. Also eliminated reference to a refueling water storage system for BWRs since the SRP-UDP could not locate any other regulatory reference to a refueling water storage system that is important to safety for BWRs. Reference to such a system is moved to the list of PWR systems. SRP Draft Section 3.2.2 Attachment A - Proposed Changes in Order of Occurrence Item Source Description DRAFT
