ironment will be monitored, and that appropriate actions will be taken if significant changes occur in the material fracture toughness that may affect the integrity of the reactor vessel, and thus its ability to accomplish the safety functions under all anticipated and postulated conditions. 10. In Staff Requirements - SECY-05-0197 - Review of Operational Programs in a Combined License Application and Generic Emergency Planning Inspections, Tests, Analyses, and Acceptance Criteria, dated February 22, 2006, the Commission approved Revision 2 - March 2007 5.3.1-13 the use of a license condition for operational program implementation milestones that are fully described or referenced in the final safety analysis report. Implementation of this program will be inspected in accordance with NRC Inspection Manual Chapter IMC-2504, “Construction Inspection Program - Non-ITAAC Inspections.” III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 1. Materials. The materials for the reactor vessel and its appurtenances and attachments are compared with the acceptable materials identified in the Code, Section III, Appendix I. Materials not listed in the Code are clearly identified. 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 reviewer has taken exception to the use of a specific material the applicant is advised which material is not acceptable, and the reason for disapproval. 2.
