Content:
essel components most likely to be the source of leakage. Meeting the requirements of GDC 53 provides assurance that containment penetrations will function as designed in terms of leakage and will not contribute unduly to offsite radiation doses.30 3. Compliance with GDC 54 requires that piping systems penetrating primary reactor containment be provided with leak detection, isolation, and performance testing capabilities. GDC 53 applies to SRP Section 6.2.6 because the review broadly covers containment testing. The requirements of GDC 54 are imposed so that unanticipated leakage from piping systems penetrating the reactor containment will not occur during the recovery period that follows a loss-of-coolant accident (LOCA). Such leakage would compromise the ability of the system to limit the release of fission products to the environment. Meeting this requirement provides assurance that piping systems penetrating the reactor containment will not be an additional source of leaking fission products and, hence, that releases of fission products off site will not result in radiation doses in excess of the guideline doses specified in 10 CFR Part 100.31 4. Appendix J to 10 CFR Part 50 specifies requirements and acceptance criteria for preoperational and periodic testing of the leaktightness of the reactor containment and penetrations. Appendix J applies to SRP Section 6.2.6 because it contains detailed requirements concerning the manner in which the reactor containment and its parts must be tested. These tests include (a) periodic integrated leak rate tests, (b) local testing of containment penetration leakage rates, and (c) local testing of isolation valve leakage rates. Appendix J includes pertinent information on the frequency of testing, pressures at which tests will be conducted, reporting of test results, and acceptance criteria for testing. Meeting the requirements of Appendix J to 10 CFR Part 50 provides assurance that the leaktightness of the containment will be
