reactor coolant pressure boundary, b. the capability to shut down the reactor and maintain it in a safe shutdown condition, c. the capability to prevent or mitigate the consequences of accidents which could result in potential offsite exposures comparable to the guideline exposures of 10 CFR Part 100. To meet the requirements of General Design Criterion 2 and 10 CFR Part 100, Appendix A, the following regulatory guide is used: Regulatory Guide 1.29, 3.2.1-2 Rev. 1 - July 1981 "Seismic Design Classification." This guide describes an acceptable method of identifying and classifying those plant features that should be designed to withstand the effects of the SSE. III. REVIEW PROCEDURES Selection and emphasis of various aspects of the areas covered by this SRP section will be made by the reviewer on each case. The judgement on the areas to be given attention during the review is to be based on an inspection of the material presented, the similarity of the material to that recently reviewed on other plants, and whether items of special safety significance are involved. Regulatory Guide 1.29, which identifies structures, systems, and components of light-water-cooled reactors on a functional basis, is the principal document used for identifying those plant features important to safety which, as a minimum, should be designed to seismic Category I requirements. The staff review should establish whether the applicant has indicated compliance with Regulatory Guide 1.29 in the SAR. Where there are differences with respect to the Guide, these differences should be identified. For General Electric BWR/6 main steam lines and main feedwater lines, an acceptable alternate seismic classification to that currently specified in Position C.1.e of Regulatory Guide 1.29, is provided in Figure B-1 attached to Appendix B of SRP Section 3.2.2. The information -in the SAR identifying seismic Category I structures, systems, and components is reviewed for completeness and to assure there is
