Drywell 3.6.5.1 SURVEILLANCE REQUIREMENTS (continued)
SURVEILLANCE I
FREQUENCY SR 3.6.5.1.3 Verify bypass leakage iB less than or equal to the bypass leakage limit.
However, during the first unit startup following bypass leakage testing performed in accordance with this SR, the acceptance criterion is 5 10% of the drywell bypass leakage limit.
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 AND 48 months following a test with bypass leakage greater than the bypass leakage limit AND
NOTES-----
- 1. The next required performance of this SR may be delayed to November 23, 20DB.
- 2. SR 3.0.2 is not applicable for extensions
> 12 months; 120 months (continued)

Programs and Manuals 5.5 5.5 Programs and Manuals (continued) 5.5.13 Primary Containment Leakage Rate Testing Program A program shall be established to implement the leakage rate testing of the primary containment as required by 10 CPR 50.54 (o) and 10 CFR 50, Appendix J, Option B, as modified by approved exemptions. This program shall be in accordance with the guidelines contained in Regulatory Guide 1.163, 'Performance-Based Containment Leak-Test Program,' dated September 1995,as modified by the following exceptions:
(1) Bechtel Topical Report EN-TOP-1 is also an acceptable option for performance of Type A tests, and (2) NEI 94 1995, Section 9.2.3: The first Type A test performed after November 23, 1993 shall be performed no later than November 23, 2008.
The peak calculated containment internal pressure for the design basis loss of coolant accident, P., is 9.0 psig.
The maximum allowable primary containment leakage rate L., at P.,
shall be 0.65V of primary containment air weight per day.
Leakage Rate acceptance criteria are:
- a. Primary containment leakage rate acceptance criterion is S 1.0 L..
During the first unit startup following testing in accordance with this program, the leak rate acceptance criteria are 5 0.60 L, for the Type B and Type C tests and S 0.75 La for Type A tests;
- b. Air lock testing acceptance criteria are:
- 1) Overall air lock leakage rate is S 5 scfh when tested at
> P.,
- 2)
For each door, leakage rate is S 5 scfh when the gap.
between door seals is pressurized k Pa.
The provisions of SR 3.0.2 do not apply to the test frequencies specified in the Primary Containment Leakage Rate Testing Program.
The provisions of SR 3.0.3 are applicable to the Primary Containment Leakage Rate Testing Program.
