Wallis, G., “The ANSI/ANS Standard 58.2-1988: Two Phase Jet Model,” September 14, 2004, ADAMS Accession No. ML050830344. 3.6.2-19 Revision 3 – December 2016 SRP Section 3.6.2 Description of Changes Section 3.6.2, “Determination Of Rupture Locations And Dynamic Effects Associated With The Postulated Rupture Of Piping” This section has been updated to reflect the applicability of regulatory treatment of non-safety systems (RTNSS) category “B” structures, systems, and components in the review of the dynamic effects associated with postulated pipe rupture, consistent with SRP Section 19.3, and to address potential non-conservatism of ANSI/ANS 58.2 Standard’s Jet Modeling. In addition to the changes itemized below, editorial changes were made throughout for clarity, consistency, and applicability. Changes incorporated into Revision 3 include: I. AREAS OF REVIEW • Applicability of this SRP section to various classifications of SSCs was clarified. • A pointer to SRP Chapters 17 and 19 for the review of probabilistic risk assessment and quality was added for clarity. II. ACCEPTANCE CRITERIA • Details were added to the requirements of GDC 4 as it pertains to the effects of postulated accidents including environmental effects. • Technical Rationale was updated to include RTNSS-B SSCs. III. REVIEW PROCEDURES • Procedures addressing the requirements of 10 CFR 52.47(a), 52.79(a), and 50.34(f) were added for clarity, and to address operating experience requirements. • Procedures to determine review responsibilities as identified in the reviews in SRP Sections 3.2.2 and 19.3 were added, including changes to address the review of risk-significant SSCs. • A reference to the Appendix A discussion on potential non-conservatism of ANSI/ANS 58.2 was added. IV. EVALUATION FINDINGS • Section was updated to address the review of risk-significant SSCs. 3.6.2-20 Revision 3
