e are clearly identified, and the basis evaluated. -The reviewer judges the significance of the exceptions and, taking into account precedents set in earlier cases, determines the acceptability of the proposed exceptions. In those instances where the Materials Engineering Branch takes exception to the use of a specific material or questions certain aspects of a specification, the applicant is advised which material is not acceptable, and for what reason. 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 compati- bility with the coolant, contaminants, and radiolytic products to which the materials may be exposed in service. (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. e .Z^.3-n .. Hey................... n - 1jy ... 10.. I~s 5.2. 3-10 Rev. 2 - July 1981 b. At the operating license stage of the review process: (1) The items listed under subsection II.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 include Charpy V-notch impact and dropweight tests. A description of the tests is reviewed, and the locations of the test specimens and their
