Content:
e results of the seismic system and subsystem analyses are checked to verify that sufficient information as specified in subsection II.4 of this SRP section is included. Any deficiency in the required information is identified and the applicant ais requested to provide further 16 information. 5. InserviceInstrument Surveillance17 The inservice inspectioninstrument surveillance program described by the applicant is 18 reviewed to assure that the acceptance criteria of subsection II.5 of this SRP section are met. The staff accepted an exemption in both the ABWR and System 80+ design certification FSERs to eliminate the OBE from seismic design considerations. Justification for the exemption was based in part on the licensees' commitment to develop additional seismic related procedural requirements. These additional requirements were primarily concerned with criteria for determining whether or not a reactor would be shutdown following an earthquake, pre- earthquake planning activities, and post-earthquake damage inspections. For the design certifications the Staff also reviewed criteria in EPRI NP-5930 (Reference 5) and documented in the ABWR FSER several exceptions relating to the adequacy of seismic instrumentation. (New rules and regulatory guides are currently being drafted by the Staff to provide additional guidance relating to the elimination of the OBE from design considerations.)19 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,
