PRINARY CONTAINMENT LEAK RATE TESTING PROGRAM A program shall be established to implement the leak 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, entitled "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 10CFR50, Appendix J":
Section 9.2.3:
The first Type A test after the April 1995 Type A test shall be performed no later than November 2005.
The peak calculated containment internal pressure for the design basis loss of coolant accident, Pa, is 44 psig.
The maximum allowable primary containment leak rate, La, at Pa, shall be 0.8% of primary containment air weight per day.
Leak rate acceptance criteria are:
- 1.
Primary containment leak rate acceptance criterion < 1.0 La.
- 2.
The as-left primary containment integrated leak rate test (Type A test) acceptance criterion is < 0.75 La.
- 3.
The combined local leak rate test (Type B and C tests) acceptance criterion is < 0.60 La, calculated on a maximum pathway basis, prior to entering a mode of operation where containment integrity is required.
- 4.
The combined local leak rate test (Type B and C tests) acceptance criterion is < 0.60 La, calculated on a minimum pathway basis, at all times when primary containment integrity is required.
- 5.
Airlock overall leak rate acceptance criterion is < 0.10 La when tested at > Pa.
The provision of the Definition (1.0.Y) for Surveillance Frequency does not apply to the test frequencies specified in the Primary Containment Leak Rate Testing Program.
D.
Radioactive Effluent Controls Program This program conforming to 10 CFR 50.36a provides for the control of radioactive effluents and for maintaining the doses to members of the public from radioactive effluents as low as reasonably Amendment No. -,
