he 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.20 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and histhe review supports 21 conclusions of the following type, to be included in the staff's safety evaluation report: The staff concludes that the seismic instrumentation system provided for the plant is acceptable and meets the requirements of General Design Criterion 2, Appendix A to 10 3.7.4-7 DRAFT Rev. 2 - April 1996 CFR Part 100, Appendix A and 10 CFR Part 50, 50.55a. This conclusion is based on 22 the following: The applicant has met the requirements of 10 CFR Part 100, Appendix A by providing the instrumentation that is capable of measuring the effects of an earthquake which meets the requirements of GDC 2. The applicant has met the requirements of 10 CFR Part 50, 50.55a by providing the inservice inspectionan instrument surveillance program that 23 will verify operability by performing channel checks, calibrations, and functional tests at acceptable intervals. In addition, the installation of the specified seismic instrumentation in the reactor containment structure and at other Category I structures, systems, and components constitutes an acceptable program to record data on seismic ground motion as well as data on the frequency and amplitude relationship of the seismic response of major structures and systems. A prompt readout of pertinent data at the control room can be expected to yield sufficient information to guide the operator on a timely basis for the purpose of evaluating the seismic response in the event of an earthquake. Data obtained from such installed seismic instrumentation will be sufficient to determine that the seismic analysis assumptions and the analytical model used for the design of the plant are adequate and
