eviewer determines that the materials proposed for the steam and feedwater systems are in conformance with Appendix I to Section III and to Parts A, B, and C of Section II of the Code. A. The reviewer verifies the acceptability of any proposed material that is not included in Appendix I to Section III and Parts A, B, and C of Section II of the ASME Code or in Regulatory Guide 1.84. B. The reviewer determines that the methods for qualifying welders for making welds in locations of restricted direct physical and visual accessibility, and the methods for monitoring and certifying production welds in such areas are in accordance with the acceptance criteria stated in subsection II.1(C) of this SRP section. C. The reviewer verifies the adequacy of controls placed on the welding procedures for carbon or low alloy steel components. The reviewer confirms that the 10.3.6-7 Revision 3 - March 2007 preheat temperatures used for welding are in accordance with the references specified in subsection II.1.D of this SRP section, or that justification has been provided for alternatives to these specified preheat temperatures. D. The reviewer determines that the methods for cleaning and handling the Class 2 and 3 components are in accordance with acceptance criteria stated in subsection II.1.(E) of this SRP section. E. The reviewer verifies that the tubular products are examined in accordance with acceptance criteria stated in subsection II.1.F of this SRP section. F. If austenitic stainless steel materials are used in the design of the steam or feedwater systems, the reviewer verifies that the applicant has adequately addressed the potential for IGSCC. The reviewer uses the applicable criteria of SRP Section 5.2.3, "Reactor Coolant Pressure Boundary Materials," as they relate to material selection and fabrication process controls for austenitic stainless steel. 2. Fracture Toughness of Class 2 and 3 Components The reviewer determines that fracture toughness properties of components
