ng is treated as ASME Code Class piping for purposes of examination and pressure testing. The sample selection process is examined to verify that expansion of the sample size is in accordance with the acceptance criteria of Section II.2.1 of this SRP. Also, the additional examinations should be performed in accordance with the ASME Code. Currently, the ASME Code directs users to perform additional examinations during the current outage. Inspection methods selected by the licensee are examined to verify that they address the degradation mechanisms, pipe sizes, and materials of concern. The RI-ISI inspection program is reviewed to confirm that appropriate examination methods and intervals are used and acceptance standards meet the requirements of ASME B&PVC Section XI or existing regulatory guidance applicable to the piping system. IV ELEMENT 4: DOCUMENTATION The reviewer will review the licensee’s submittal to ensure that it contains the documentation necessary to conduct the review described in this SRP (i.e., the documentation described in Regulatory Guide 1.178). The RI-ISI program and its updates should be maintained on site and available for NRC inspection consistent with the requirements of Appendix B to 10 CFR Part 50. V EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and that the evaluation is sufficiently complete and adequate to support conclusions of the following types, to be included in the staff’s safety evaluation report. The staff concludes that the licensee’s proposed RI-ISI program, as described in its submittal, will provide an acceptable level of quality and safety pursuant to 10 CFR 50.55a(a)(3)(i) with regard to the number of inspections, locations of inspections, and methods of inspections. This conclusion is based on the following findings. The staff finds that the results of the different elements of the engineering analysis are considered in an integrated decisionmaking process. The impact of the
