NEDO-32164, Revision 0, "Mitigation of BWR Core Thermal-Hydraulic Instabilities in ATWS," General Electric Company, December 1992.136 4.4-17 DRAFT Rev. 2 - April 1996 APPENDIX137 STANDARD REVIEW PLAN 4.4 INDEPENDENT AUDIT ANALYSIS (Appendix to SRP Section 4.4 has been deleted) DRAFT Rev. 2 - April 1996 4.4-18 [This Page Intentionally Left Blank] SRP Draft Section 4.4 Attachment A - Proposed Changes in Order of Occurrence 4.4-19 DRAFT Rev. 2 - April 1996 Item numbers in the following table correspond to superscript numbers in the redline/strikeout copy of the draft SRP section. Item Source Description 1. Current PRB names and Editorial change to reflect the current PRB name and abbreviations. responsibility for SRP Section 4.4. 2. Current PRB names and Editorial change to identify that there are currently no abbreviations. secondary PRBs for SRP Section 4.4. 3. GSI B-3 Resolution. Corrected "anticipated operational transients" to be "anticipated operational occurrences." 4. Editorial Added text to define the first use of the acronyms CHF and CPR. 5. Integrated Impact 1397 This area of review describes the review for new plant applicants of the thermal-hydraulic design during shutdown and low-power conditions. 6. GSI B-3 Resolution. "postulated accident conditions" was revised to be "design-basis accident conditions." 7. Integrated Impact 221. Added Area of Review for determining the acceptability of the core thermal-hydraulic design under ATWS conditions. 8. Current PRB names and Editorial change to reflect the current PRB with abbreviations. responsibility for review of the Inadequate Core Cooling (ICC) monitoring system. Although this area was previously reviewed by the Instrumentation and Control System Branch (ICSB) [now the Instrumentation and Controls Branch (HICB)] as a secondary review responsibility for SRP Section 4.4, this secondary review responsibility no longer exists. Additionally, the HICB has stated in comments received on Integrated Impacts for SRP
