OCEDURES The reviewer will select and emphasize material from the procedures described below, as may be appropriate for a particular case. For the areas of review described in subsection I of this SRP section, the review procedure is as follows: 1. Material Specifications The list of the materials of construction of the components of the reactor internals that are exposed to the reactor coolant is reviewed. The material specifications for each component or part used in the reactor internals are compared with the acceptable specifications listed in the Code, Sections II and III, as shown in the acceptance criteria. Any exceptions to the Code 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. 4.5.2-3 Rev. 2 - July 1981 2. Controls on Welding The information submitted by the applicant is reviewed to provide assurance that welding of materials used for components of the reactor internals is in accordance with the procedures of the Code, Section III, NG-4000. The controls on welding, discussed in. SRP Section 5.2.3, are considered applicable to welding of reactor internals, and information in this area is verified. The reviewer assures that any special welding process or welding control conforms to the qualification requirements of the Code, Section IX, or that justification is made for any deviation. 3. Nondestructive Examination of Wrought Seamless Tubular Products The information submitted by the applicant is reviewed to determine methods used for nondestructive examination. The Code, Section III, NG-2500 speci- fies that 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 of review and review procedures follow those spelled out in SRP Section 5.2.3, "Reactor Coolant
