will be monitored, and that appropriate actions will be taken if significant changes occur in the material fracture toughness that may effect the integrity of the reactor vessel, and thus its ability to accomplish the safety functions under all anticipated and postulated conditions. III. REVIEW PROCEDURES The reviewer will select and emphasize material from the procedures described below, as may be appropriate for a particular case. For each area of review specified in subsection I of this SRP section, the review procedure is as follows: 1. Material Specifications The material specifications for the reactor vessel and its appurtenances are compared with the acceptable specifications listed in the Code, Section III, Appendix I, and Section II, Parts A, B, C. Materials not listed in the Code, or deviations in a listed specification, are clearly identified, and the bases for deviation or nonconformance evaluated. A study of the suitability of the material and comparisons with precedents set in earlier cases enable the reviewer to determine the acceptability of the proposed exceptions. In those instances where the Materials Engineering Branch EMCB has taken exception to the use of a 73 specific material, or questions certain aspects of a specification, the applicant is advised which material is not acceptable, and the reason for disapproval. 2. Special Processes Used for Manufacture and Fabrication of Components Information on special processes used for manufacture and fabrication of the reactor vessel and its appurtenances is reviewed to (1) identify each special process, (2) DRAFT Rev. 2 - April 1996 5.3.1-14 determine whether there are any Code restrictions on its use, (3) establish the adequacy of the process in providing components with suitable mechanical and physical properties, (4) establish the effects of such processes on the stress-corrosion characteristics of the material, and (5) identify whether special requirements for nondestructive examination are
