CFR Title: 

Content:
entation diagrams, and descriptive information. The staff concludes that the facility design for protection against postulated piping failures outside containment is acceptable and therefore meets the requirements of 10 CFR Part 50, Appendix A, GDC 2, GDC 4, 10 CFR 52.47(b)(1), and 10 CFR 52.80(a) with respect to accommodating the environmental effects of postulated pipe ruptures. The applicant has met the requirement of GDC 2 by considering the environmental effects from the rupture of non-seismic piping, and the applicant has met the requirement of GDC 4 with respect to postulated pipe ruptures by conforming to BTP 3-3. 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apply to reviews of applications submitted six months or more after the date of issuance of this SRP section, unless superseded by a later revision. Implementation schedules for conformance to parts of the method discussed herein are contained in the referenced Branch Technical Positions. VI.
