REVIEW RESPONSIBILITIES Primary - Hydrologic & Geotechnical Engineering Branch (HGEB)Civil Engineering and Geosciences Branch (ECGB)1 Secondary - None I. AREAS OF REVIEW The hydrometeorologic design basis is developed in this section of the safety analysis report (SAR) to assure ensure that safety-related facilities and water supply are not affected by ice 2 flooding or blockage. The areas of review include: 1. The regional history and types of historical ice accumulations (i.e., ice jams, wind-driven ice ridges, floes, etc.). 2. The potential for ice-produced forces on, or blockage of, safety-related facilities. 3. The potential effects of ice-induced high or low flow levels on safety-related facilities and water supplies. If there is evidence of potential structural effects, the Structural Engineering Branch (SEB) will be requested by HGEB to ECGB will ascertain whether these effects are properly considered in 3 the structural design basis for the plant. DRAFT Rev. 3 - April 1996 2.4.7-2 Review Interfaces4 similarly, iIf there is evidence of potential mechanical effects, the Mechanical Engineering 5 Branch (MEB)(EMEB) and the Auxiliary Plant Systems Branch (ASB SPLB) will be requested 6 7 by HGEB ECGB to ascertain whether these effects are properly considered in the mechanical 8 design basis for the plant. The staff will develop a position based on the analysis; resolve, if possible, differences between the applicant's and staff's estimates of ice effects; and write the safety evaluation report (SER) input accordingly. For those areas of review identified as part of the primary responsibility of other branches, the acceptance criteria and methods of application are contained in the referenced Standard Review Plan (SRP) section.9 II. ACCEPTANCE CRITERIA Acceptance criteria for this SRP section are based on meeting the requirements of the following regulations: 1. 10 CFR Part 50, 50.55a Appendix A, General Design Criterion 1 (GDC 1) as it requires 10 structures,
