applications) or presented by the applicant to support use of the material under the expected environmental conditions (e.g. exposure to the reactor coolant). Particular review emphasis is placed upon the corrosion resistance and stress corrosion cracking resistance properties of the proposed nickel-chromium-iron alloy(s).94 Where cast austenitic stainless steels are proposed for use in the RCPB, the reviewer verifies that the material specifications ensure adequate fracture toughness over the design life to support use of the material under the expected environmental conditions (e.g. exposure to the reactor coolant operating temperatures).95 2. Compatibility of Materials with the Reactor Coolant The reviewer verifies that the following information is provided at each respective stage of the review process: a. At the construction permit stage of review: (1) A list of the materials of construction of the components of the reactor coolant pressure boundary that are exposed to the reactor coolant, including a description of material compatibility with the coolant, contaminants, and radiolytic products to which the materials may be exposed in service. DRAFT Rev. 3 - April 1996 5.2.3-16 (2) A list of the materials of construction of the RCPB, and a description of material compatibility with external insulation and with the environment in the event of reactor coolant leakage. (3) The fabrication and cleaning controls imposed on stainless steel components to minimize contamination with chloride and fluoride ions. b. At the operating license stage of the review process: (1) The items listed under subsection III.2.a above, to provide assurance that any changes are noted that may have occurred during the period between the submittal of SARs. 3. Fabrication and Processing of Ferritic Materials a. The information submitted by the applicant relative to tests for fracture toughness is reviewed for conformance with the acceptance criteria stated in subsection II.3.a. These tests
