tainment design pressure. 6.2.6-7 Revision 3 - March 2007 GDC 52 applies to SRP Section 6.2.6 because the review focuses on containment leakage rate testing, which includes the integrated leakage rate testing specified in GDC 52. The requirement for integrated leakage rate testing of the reactor containment is imposed to ensure that it will function as designed in the event of an accident. Meeting the requirements of GDC 52 provides assurance that the reactor containment will function as designed and that releases of fission products to the environment will not result in offsite radiation doses in excess of the reference values specified in 10 CFR Part 100. 2. Compliance with GDC 53 requires that the reactor containment be designed to permit (a) periodic inspection of penetrations, (b) an appropriate surveillance program, and (c) periodic testing of the leaktightness of penetrations with resilient seals and expansion bellows. GDC 53 applies to this SRP section because the review broadly covers containment testing. The requirement for inspection, surveillance, and periodic testing of reactor containment penetrations, particularly those with resilient seals and expansion bellows, is imposed because these penetrations are among the containment vessel 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. 3. Compliance with GDC 54 requires that piping systems penetrating primary reactor containment be provided with leak detection, isolation, and performance testing capabilities. GDC 54 applies to this SRP section 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 LOCA. Such leakage would compromise the
