subsection I of this SRP section, the review procedures isare as follows:46 1. Material Specifications The list of the materials of construction of the components offor the reactor internals that are exposed to the reactor coolant is reviewed.47 DRAFT Rev. 3 - April 1996 4.5.2-6 The material specifications for each component or part used in the reactor internals and core support structures are compared with the acceptable specifications listed in the Code, Sections II and III, and/or acceptable Code Cases identified in Regulatory Guide 1.85 as showndescribed in the acceptance criteria. Any exceptions to the Code 48 materials specifications are clearly identified. The reviewer evaluates the basis for the exceptions, taking into account precedents set in earlier cases, and determines the acceptability of such materials. 2. Controls on Welding The information submitted by the applicant is reviewed to provide assurance that welding methods and controls applied of materials used for components offor the reactor internals and core support structures isare in accordance with the procedures of the Code, Section 49 III, Division 1 , NG-4000. The controls on welding, discussed in SRP Section 5.2.3, are 50 also considered applicable to welding of reactor internals, and information in this area isconformance with these welding controls is verified. The reviewer assures that any 51 special welding processes or welding controls conforms to the qualification requirements of the Code, Section IX, or that justification is made for any deviation.52 3. Nondestructive Examination of Wrought Seamless Tubular Products53 The information submitted by the applicant is reviewed to determine methods used for nondestructive examination. The Code, Section III, Division 1, NG-2500 specifies that 54 examination by either radiographic or ultrasonic examination is acceptable. 4. Austenitic Stainless Steel The materials and fabrication procedures used for reactor internals are reviewed. The areas
