SRP Draft Section 6.2.3 Attachment A - Proposed Changes in Order of Occurrence Item Source Description 6.2.3-19 DRAFT Rev. 3 - April 1996 27. Editorial 10 CFR 50 Appendix J does not explicitly provide design requirements for secondary containment testability. Appendix J also does not explicitly provide requirements for secondary containment preoperational testing. 10 CFR 50 Appendix J requires that structures of multiple barrier or subatmospheric containments (e.g., secondary containments for boiling water reactors and shield buildings for pressurized water reactors that enclose the entire primary reactor containment or portions thereof) shall be subject to individual tests in accordance with the procedures specified in the technical specifications, or associated bases. Also clarified, based upon the leakage rate testing requirements of Appendix J, that the purpose of leakage rate testing is not only to identify leakage paths but to determine leakage rates. 28. SRP-UDP format item. Format change to make the citation of references consistent with the SRP-UDP format guidance. Also updated the reference number to reflect added references. 29. Editorial Corrected error, probably typographical. 30. SRP-UDP format item, Metrication The existing criteria of 0.25 inches (water) for pressure policy implementation differential was converted to 0.063 kPa using the guidance of Federal Standard 376B. See enclosed conversion documentation. 31. Editorial Revised to reflect that neither 10 CFR 50 Appendix J nor GDC 43 explicitly provide requirements for secondary containment inspection. Appendix J provides testing requirements applicable to the secondary containment. 32. SRP-UDP format item. Format change to make the citation of references consistent with the
