rials are compatible with the primary coolant water, which is chemically controlled in accordance with appropriate technical specifications. This compatibility has been proven by extensive testing and satisfactory performance. This includes conformance with the recommendationspositions of Regulatory Guide 1.44, "Control of Sensitized Stainless Steel," and [for BWRs only] conformance with the requirements of NUREG-0313staff positions of Generic Letter 88-01 which are based upon the technical information and recommendations provided in NUREG-0313, Revision 2 . The cast austenitic stainless steels and nickel-chromium-iron alloys to be 111 5.2.3-21 DRAFT Rev. 3 - April 1996 used as RCPB materials have also been demonstrated to be compatible with reactor coolant under the anticipated environmental conditions of RCPB service. General 112 corrosion of all materials, except unclad carbon and low alloy steel, will be negligible. For these materials, conservative corrosion allowances have been provided for all exposed surfaces in accordance with the requirements of the Code, Section III. The above evidence of compatibility with the coolant and compliance with the Code provisions satisfy the requirements of GDC 4 relative to compatibility of components with environmental conditions. The materials of construction for the RCPB are compatible with the thermal insulation used in these areas and are in conformance with the recommendations of Regulatory Guide 1.36, "Nonmetallic Thermal Insulation for Austenitic Stainless Steels." Conformance with the above recommendations satisfy the requirements of GDC 14 and GDC 31 relative to prevention of failure of the RCPB. The ferritic steel tubular products and the tubular products fabricated from austenitic stainless steel have been found to be acceptable by nondestructive examinations in accordance with the provisions of the ASME Code, Section III. Compliance with these Code requirements satisfies the quality standards requirements of GDC
