that onsite cleaning and cleanliness control procedures are satisfactory and in accordance with subsection II.4 of this SRP section. 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.53 DRAFT Rev. 3 - April 1996 4.5.1-8 IV. EVALUATION FINDINGS When the reviewer has verified that sufficient and acceptable information has been provided in accordance with the requirements of this SRP section, conclusions of the following type are prepared, to be included in the staff's safety evaluation report: The staff concludes that the control rod drive mechanism structural materials are acceptable and meet the requirements of General Design Criteria 1, 14, and 26 as well as 10 CFR Part 50, Section 50.55a. This conclusion is based on the applicant having demonstrated that the properties of materials selected for the control rod drive mechanism components exposed to the reactor coolant satisfy Appendix I of Section III, Division 1 of the ASME Code, and Parts A, B, and C of Section II of the Code, and 54 having conformed with the staff position that the yield strength of cold-worked 55 austenitic stainless steel should not exceed 620 MPa (90,000 psi) . For materials not 56 selected in accordance with ASME Code provisions, Tthe applicant has met the guidelines of Regulatory Guide 1.85 by usingused materials of construction that are approved for use to in accordance with the acceptable ASME code cases described in Regulatory Guide
