nt required for maintenance and equipment undergoing maintenance. The new review procedure is consistent with the staff guidance documented in section 3.5.1.2 of the ABWR FSER and addresses the issues discussed in NRC Notice 80-21. 34. Integrated Impact # 787 A new paragraph was added to the review procedures to address the application of probability calculations used to evaluate the statistical significance of identified missiles. Because this change is based upon reviews documented in the ABWR FSER, the applicability of this new review procedure was limited to evolutionary plants only. The review procedure is consistent with the staff positions documented in section 3.5.1 of the ABWR FSER. 35. Integrated Impact # 788. A new review procedure for Evolutionary plants was added addressing use of the high-energy line spatial separation analysis in determining if adequate protection is demonstrated for SSC important to safety from missiles that may be generated inside of containment. The methods described in this Review Procedure are consistent with the approach documented in section 3.5.1.2 of the ABWR FSER. SRP Draft Section 3.5.1.2 Attachment A - Proposed Changes in Order of Occurrence Item Source Description 3.5.1.2-11 DRAFT Rev. 3 - April 1996 36. SRP-UDP Guidance, Implementation Added standard paragraph to address application of of 10 CFR 52 Review Procedures in design certification reviews. 37. Editorial. Added the acronym SSC for structures, systems, or components as is consistent with the remainder of the section. 38. Editorial. Use of the phrase "essential structures, systems, and components" was replaced with the term "SSC important to safety." Use of the term "SSC important to safety" is consistent with GDC 4 and with the terminology used in the remainder of the section to identify those SSC that have a safety concern involving missile protection. 39. Editorial. Use of the term "safety-related SSC" is not comprehensive and was therefore replaced with broader
