listed in the Code, Section III, Appendix I, and are presented in detail in Code Section II, Parts A, B, and C. The materials must also meet the specifications requirements of 10 CFR Part 50, Appendix G. b. The acceptability of materials not specified in the Code are considered on an individual basis. Their suitability is evaluated on tne basis of data submitted in accordance with the requirements of Code Section III, Appendix IV-1400 and 10 CFR Part 50, Appendix G. These data must include information 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 § 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 accordance with Code Section III, Para- graph 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, Paragraph NA-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 § 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, for normal methods of exam- ination. When special techniques or procedures are developed, they must be equivalent or superior to the techniques described in Appendix IX-6000 of Code Section III, and must be proven so, by demonstration on the spe- cific type of component part. 5.3.1-4
