nspecting agency for review and approval prior to use. 4. Special Controls and Special Processes Used for Ferritic Steels and austenitic stainless steel. The controls on welding of ferritic steels and austenitic stainless steels discussed in Standard Review Plan Section 5.2.3, "Reactor Coolant Pressure Boundary Materials," are considered applicable to welding of the reactor vessel and its components. The reviewer verifies that any special welding control or special welding process is able to conform to the qualification requirements of the Code, Section IX, or that justification is made for this deviation. The reviewer also reviews the controls (before, during, and after welding of austenitic stainless steel) to avoid contamination and sensitization that could increase the possibility of stress corrosion cracking in austenitic stainless steel. Additionally, controls to avoid underclad cracking during weld cladding of the reactor vessel are reviewed. 5.3.1-15 DRAFT Rev. 2 - April 1996 The abrasive work controls for austenitic stainless steel surfaces are reviewed and are verified as adequate to minimize the introduction of stress corrosion cracking promoting contaminants and the cold-working of surfaces.74 For BWRs, the reactor vessel attachments and appurtenances are reviewed for conformance with the staff positions of Generic Letter 88-01 or the recommendations of NUREG-0313 with regard to protection against IGSSC in or near weldments to the reactor vessel.75 5. Fracture Toughness The information submitted by the applicant relative to tests for fracture toughness is reviewed for conformance with the Code, Section III, paragraph NB-2300, and Appendix G of 10 CFR Part 50. These tests include Charpy V-notch impact tests and dropweight tests. A description of the tests is reviewed, and the location of the test specimens and their orientation are verified. Information regarding calibration of instruments and equipment is reviewed for conformance to Code Section III,
