SURVEILLANCE REQUIREMENTS SR 3.6.5.1.1 GRAND GULF SURVEILLANCE Verify bypass leakage is less than or equal to the bypass leakage limit. However, during the first unit startup following drywell bypass leak rate testing performed in accordance with this SR, the acceptance criterion is leakage 5 10% of the bypass leakage limit. 3.6-53 Drywell 3.6.5.1 FREQUENCY 24 months following 2 consecutive tests with bypass leakage greater than the bypass leakage limit until 2 consecutive tests are less than or equal to the bypass leakage limit 48 months following a test with bypass leakage greater than the bypass leakage limit SR 3.0.2 is not applicable for extensions >. 12 months. 120 months, except that the next drywell bypass leak rate test performed after the October 19, 2008 test shall be performed no later than the plant restart after the End of Cycle 22 Refueling Outage.

Changes to the Bases of the TS shall be made under appropriate administrative controls and reviews. b. Licensees may make changes to Bases without prior NRC apptoval provided the changes do not require either,of the following: 1. A change in the TS incorporated in the license; or 2. A change to the updated FSAR or Bases that requires NRC approval pursuant to 10 CFR 50.59. c. The Bases Control Program shall contain provisions to ensure that the Bases are maintained consistent with the UFSAR. d. Proposed-changes that do not meet the criteria of either Specification 5 .. 5.11.b.l or Specification 5.5.11.b.2 above shall be ~eyie0ed and approved by the NRC prior to implementation.,: Changes to the Bases implemented without prior NRC approval shall be provided to the NRC on a frequency consi~fent with 10 CFR 50.71(e). 10 CFR 5 0, Appendix -.~J, Testing Program This program establishes the leakage rate testing program of the containment as 'required by 10 CFR 50.54(0) and 10 CFR 50, Appendix J, Option B, as modified by approved exemptions. This program shall be implemented in accordance with the Safety Evaluation issued by the Office of Nuclear Reactor Regulation dated April 26, 1995 (GNRI-95/00087) as modified by the Safety Evaluation issued fqr Amendment No. 135 to the Operating License, except that the next*. Type A test performed after the October 19, 2008 Type A test shall be performed no later than the plant restart after the Er:id of Cycle 22 Refueling Outage. For Type B and Type C local le~kage rate testing, this program shall be in accordanqe with the *guidelines contained in NEI 94-01, Revision 3-A, "Industry Guideline for Implementing Performance-Based Option of 10 CFR Part 50r .;.,,ppendix J," dated July 2012. Consistent with standard scheduling practices for Technical Specifications required surveillances, intervals for the recommended surveillance frequency for Type A testing may be extended by up to 25 percent of the test interval, not to exceed 15 months.
