Content:
g conditions to ensure adequate safety margins against nonductile or rapidly propagating failure are in conformance with the fracture toughness criteria of Appendix G to 10 CFR Part 50 and Appendix G, “Protection Against Nonductile Failure,” of the ASME Boiling and Pressure Vessel Code. The applicant has adequately addressed the upper-shelf energy criteria in accordance with Appendix G to 10 CFR Part 50 and thermal shock events in accordance with 10 CFR 50.61 [PWRs only]. The staff concludes that the use of 5.3.2-14 Revision 2 - March 2007 operating limits, based upon the criteria defined in SRP Section 5.3.2, provides reasonable assurance that nonductile or rapidly propagating failure will not occur, and constitutes an acceptable basis for satisfying the applicable requirements of 10 CFR 50.55a, 10 CFR 50.60, and 10 CFR 50.61 [PWRs only] and GDC 1, 14, and 31 of Appendix A to 10 CFR Part 50. 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. 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. V. IMPLEMENTATION 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 described herein to evaluate conformance with Commission regulations. The provisions of this SRP section apply to reviews of applications submitted six months or more after the date of issuance of this SRP section, unless superseded by a later revision. VI.
