Text

e. Closure of the containment isolation valves for the purpose of the test shall be accomplished by the means provided for normal operation of the valves.

2. Acceptance Criteria The As Found measured leakage rate shall be less than 1.0 La where La is equal to 0.1 w/o per day of containment steam air atmosphere at 47 psig and 271°F, which are the peak accident pressure and temperature conditions. Prior to entering a mode where containment integrity is required, the As Left leakage rate shall not exceed 0.75 La.

3. Frequency The integrated leakage rate test frequency shall be performed in accordance with 10 CFR 50 Appendix J, Option B as modified by approved exemption and in accordance with guidelines contained in Regulatory Guide 1.163, dated September 1995, with the following exceptions:

Exception 1: The Type A testing frequency specified in NEI 94-01 paragraph 9.2.3 as at-least-once-per-10 years based on acceptable performance history is changed to allow a Type A testing frequency of at-least-once-per-15 years based on acceptable performance history. This is a one-time-only exception that applies only for the interval following the Type A test performed in June 1991.

B. SENSITIVE LEAKAGE RATE

1. Test A sensitive leakage rate test shall be conducted with the containment penetrations, weld channels, and certain double-gasketed seals and isolation valve interspaces at a minimum pressure of 52 psig and with the containment building at atmospheric pressure.

2. Acceptance Criteria The test shall be considered satisfactory if the leak rate for the containment penetrations, weld channel and other pressurized zones is equal to or less than 0.2% of the containment free volume per day.

3. Frequency A sensitive leakage rate test shall be performed at every Refueling Interval (R#).
