mation on mechanical properties, weldability, and physical changes of the material. 2. Special Processes Used for Manufacture and Fabrication of Components. The requirements of GDC 1 and 30 and 10 CFR 50.55a regarding quality standards are met by compliance with the provisions of the ASME Code, Section III, for fabrication of components. The reactor vessel and its appurtenances are fabricated and installed in Revision 2 - March 2007 5.3.1-6 accordance with Code Section III, Paragraph NB-4100. The manufacturer or installer of such components is required to certify, by application of the appropriate Code Symbol and completion of an appropriate data report in accordance with Code Section III, Article NCA-8000, that the materials used comply with the requirements of NB-2000, and that the fabrication or installation comply with the requirements of NB-4000. 3. Special Methods for Nondestructive Examination. The requirements of GDC 1 and 30 and 10 CFR 50.55a regarding quality standards are met by compliance with the ASME Code, Section III, for fabrication nondestructive testing. The acceptance criteria for examination of the reactor vessel and its appurtenances by nondestructive examination are those specified in Code Section III, NB-5000. 4. Special Controls and Special Processes Used for Ferritic Steels and Austenitic Stainless Steels. The acceptance criteria for special controls and processes in welding austenitic or ferritic steel components are based upon the following regulatory guides, ASME Code provisions, and other regulatory documents necessary to satisfy the relevant requirements of GDC 1, 4, 14, and 30; Appendix B; and 10 CFR 50.55a. A. Only those welding processes capable of producing welds in accordance with the welding procedure qualification requirements of Code Sections III and IX may be used. Any process used shall be such that the records required by NB-4300 of Section III can be made, with the exception of stud welding, which is acceptable only for
