equirements are identified on the plant arrangement drawings. The interfaces between components and associated support structures designed to seismic Category I requirements are then checked to assure compatibility. The reviewer verifies that the seismic classification of safety-related instrumentation sensing lines is in accordance with the guidance contained in Regulatory Guide 1.151 positions C.2 and C.3. 46 Structures, systems, and componentsSSCs that are classified seismic Category I are also 47 reviewed to assure that these plant features are within the scope of an applicant's Quality Assurance Program. This Quality Assurance Program should be in compliance with the pertinent Quality Assurance requirements of 10 CFR Part 50, Appendix B. Regulatory Guide 1.29 is used for identifying those plant features important to safety that are within the scope of this Appendix B Quality Assurance Program. In accordance with Regulatory Guide 1.29, the pertinent quality assurance requirements of Appendix B to 10 CFR Part 50 should be applied to all activities affecting the safety-related functions of seismic Category I SSCs. If there are 48 items designated seismic Category I that are not identified as within the scope of the Appendix B Quality Assurance Program, this information is transmitted to the Quality Assurance BranchHQMB for resolution of the issue. The seismic classification review of structures, 49 systems, and componentsSSCs important to safety and the review verifying that these plant 50 features are constructed in accordance with a 10 CFR Part 50, Appendix B Quality Assurance 3.2.1-7 DRAFT Rev. 2 - April 1996 Program is normally performed concurrently with the quality group classification review of SRP Section 3.2.2. Other SSCs that may be required for operation of the facility (excluding electrical features) need not be designed to seismic Category I requirements. Those SSCs not required to be designed to seismic Category I requirements include those portions
