Content:
satisfactory performance, the specified materials are compatible with the expected environment and corrosion is expected to be negligible. The controls imposed on the reactor coolant chemistry provide reasonable assurance that the reactor internals and core support structures will be adequately protected during 70 operation from conditions which 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 performed in accordance to these recommendations provide reasonable assurance that the materials used for the reactor internals and core support structures71 will be in a metallurgical condition to preclude inservice deterioration. Conformance with requirements of the ASME Code and the recommendations of the regulatory guides constitutes an acceptable basis for meeting in part the relevant 72 requirements of General Design Criterion 1 and Section 50.55a of 10 CFR Part 50.73 For design certification reviews, the findings will also summarize, to the extent that the review is not discussed in other safety evaluation report sections, the staff's evaluation of inspections, tests, analyses, and acceptance criteria (ITAAC), including design acceptance criteria (DAC), site interface requirements, and combined license action items that are relevant to this SRP section.74 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. This SRP section will be used by the staff when performing safety evaluations of license applications submitted by applicants pursuant to 10 CFR 50 or 10 CFR 52. Except in those 75 cases in which the applicant proposes an acceptable alternate method for complying with specified portions of the Commissions regulations, the method described herein will be used by the staff in its evaluation of
