e related criteria provided in SRP Section 5.2.3, “Reactor Coolant Pressure Boundary Materials.” The controls imposed on the reactor coolant chemistry provide reasonable assurance that the reactor internals and core support structures will be adequately protected during operation from conditions that could lead to stress corrosion of the materials and loss of component structural integrity. The material selection, fabrication practices, examination and testing procedures, and control practices provide reasonable assurance that the materials used for the reactor internals and core support structures will be in a metallurgical condition that will preclude inservice deterioration. Conformance with relevant requirements of the ASME Code, or accepted Code Cases, and the recommendations of Regulatory Guides 1.31 and 1.44 and the related criteria in SRP Section 5.2.3, constitutes an acceptable basis for meeting the relevant requirements of 10 CFR 50.55a and 10 CFR Part 50, Appendix A, GDC 1. 2. For DC and COL reviews, the findings will also summarize the staff’s evaluation of requirements and restrictions (e.g., interface requirements and site parameters) and COL action items relevant to this SRP section. 3. In addition, to the extent that the review is not discussed in other SER sections, the findings will summarize the staff's evaluation of the ITAAC, including design acceptance criteria, as applicable. 4.5.2-9 Revision 3 - March 2007 V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the staff's plan for implementing this section of the Standard Review Plan. The staff will use this SRP section in performing safety evaluations of DC applications and license applications submitted by applicants pursuant to 10 CFR Part 50 or 10 CFR Part 52. Except when the applicant proposes an acceptable alternative method for complying with specified portions of the Commission’s regulations, the staff will use the method
