REVIEW RESPONSIBILITIES Primary - Materials and Chemical Engineering Branch (MTEB EMCB ) 1 Secondary - None I. AREAS OF REVIEW The following areas relating to reactor vessel materials are reviewed: 1. Material Specifications The material specifications used for the reactor vessel and applicable appurtenances, such as the shroud support, studs, control rod drive housings, vessel support skirt, stub tubes, and instrumentation housings, are reviewed and their adequacy for use in the construction of such components is assessed on the basis of the mechanical and physical properties of the materials, the effects of irradiation on these materials, their corrosion resistance, and their fabricability. Similarly, the specifications for austenitic steel and nonferrous metals specified for the above applications are reviewed with respect to mechanical properties, stress-corrosion resistance, and fabricability. 2. Special Processes Used for Manufacture and Fabrication of Components Information submitted by the applicant for any special process used in the manufacture of the product forms supplied and for their fabrication into the reactor vessel or any of its appurtenances is reviewed, and the capability of these processes to provide components with suitable mechanical and physical properties is assessed. The effects of such special DRAFT Rev. 2 - April 1996 5.3.1-2 processes on the stress-corrosion characteristics of the material, and any aspect of the process which could cause special requirements for nondestructive examinations, are reviewed. 3. Special Methods for Nondestructive Examination Nondestructive examination methods differing from those described in the ASME Boiler and Pressure Vessel Code (Reference 24) (hereafter "the Code"), Section III, are 2 reviewed. Attention is directed towards calibration methods, instrumentation, methods of application, sensitivity, reliability, and standards used. 4. Special Controls and Special Processes Used for Ferritic Steels and
