systems specified in Regulatory Guide 1.143.54 In the event an applicant intends to take exception to Regulatory Guides 1.29, 1.143 and/or 1.151, but has not provided an adequate justification for his resultant proposed seismic 55 classifications , questions are prepared by the staff which may require additional documentation 56 or analysis to establish an acceptable basis for his the proposed seismic classification. Staff 57 comments may also be prepared requesting clarification in order to assure a clear understanding of the seismic classification assigned to a system by the applicant. If the staff's questions are not resolved in a satisfactory manner, a staff position is taken requiring conformance to Regulatory Guides 1.29, 1.143, 1.151 and with the positions discussed in the above Review Procedures.58 For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.59 DRAFT Rev. 2 - April 1996 3.2.1-8 IV. EVALUATION FINDINGS The staff's review should verify that adequate and sufficient information is contained in the SAR and amendments to arrive at conclusions of the following type, which are to be included in the staff's safety evaluation report: Structures, systems and components (SSCs) (excluding electrical features) that are 60 important to safety and that are required to withstand the effects of a safe shutdown earthquake and remain functional have been classified as seismic Category I items and have been identified
