es to providing engineering controls based upon sound radiation protection principles to achieve occupational doses that are ALARA. The primary review organization and the organization responsible for the review of radiation protection should verify that the station layout and design features provided reduce the potential doses to personnel who must operate, service, or inspect station instrumentation and controls by checking that instruments specified are designed, selected, and located with consideration for long service life, ease and low frequency of maintenance and calibration. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit (ESP) or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff's safety evaluation report. The reviewer also states the bases for those conclusions. The staff concludes that the seismic instrumentation system provided for the plant is acceptable and meets the requirements of 10 CFR Part 20 and Appendix S to 10 CFR Part 50. This conclusion is based on the following: 3.7.4-8 Draft Revision 3 - August 2013 The applicant has met the requirements of 10 CFR Part 50, Appendix S by providing the instrumentation that is capable of promptly measuring the severity of the observed ground motion and by providing a program that allows for the data from the seismic instrumentation, coupled with information obtained from a plant walkdown, to be used to make the initial determination of whether the plant must be shut down.
