- d.
Proposed changes that meet the criteria of b. above shall be reviewed 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 consistent with 10 CFR 50.71(e).
5.5.12 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 CFR 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 exception to NEI 94-01, Rev.
0, "Industry Guideline for Implementing Performance-Based Option of 10 CFR 50, Appendix J":
Section 9.2.3: The first Type A test after the April 1993 Type A test shall be performed no later than April 2008.
The peak calculated primary containment internal pressure for the design basis loss of coolant accident, Pa, is 50.5 psig.
The maximum allowable primary containment leakage rate, La, at Pa is 1.2% of primary containment air weight per day.
Leakage rate acceptance criteria are:
- a.
Primary containment overall leakage rate acceptance criterion is < 1.0 La.
During the first unit startup following testing in accordance with this program, the leakage rate acceptance criteria are < 0.60 L for the combined Type B and Type C tests, and-< 0.75 ta for Type A tests;
- b.
Air lock testing acceptance criteria are:
- 1)
Overall air lock leakage rate is < 0.05 La when tested at > Pal (continued)

For each door, leakage rate is < 0.01 La when the gap between the door seals is pressurized to 0 10 psig for at least 15 minutes.
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.
