Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.13 Primary Containment Leakage Rate Testing Program (continued)
- 2.
NEI 94 1995, Section 9.2.3: The first Unit 2 Type A test performed after December 8, 1993 Type A test shall be performed prior to startup following L2R12.
- 3.
The potential valve atmospheric leakage paths that are not exposed to reverse direction test pressure shall be tested during the regularly scheduled Type A test.
The program shall contain the list of the potential valve atmospheric leakage paths, leakage rate measurement
- method, and acceptance criteria.
This exception shall be applicable only to valves that are not isolable from the primary containment free air space.
- b.
The peak calculated primary containment internal pressure for the design basis loss of coolant accident, Pa, is 39.9 psig.
- c.
The maximum allowable primary containment leakage rate, La, at P,,
is 0.635% of primary containment air weight per day.
- d.
Leakage rate acceptance criteria are:
- 1.
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 La for the combined Type B and Type C tests, and
- 0.75 La for Type A tests.
- 2.
Air lock testing acceptance criteria are:
a)
Overall air lock leakage rate is
- 0.05 L, when tested at > P,.
b)
For each door, the seal leakage rate is
- 5 scf per hour when the gap between the door seals is pressurized to Ž 10 psig.
- e.
The provisions of SR 3.0.3 are applicable to the Primary Containment Leakage Rate Testing Program.
