Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.13 Primary Containment Leakage Rate Testinq 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 no later than December 7, 2008.
- b.
The peak calculated primary containment internal pressure for the design basis loss of coolant accident, P,, is 39.9 psig.
- c.
The maximum allowable primary containment leakage rate, La, at Pa, 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 s 0.60 L, 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 s 0.05 La when tested at 2 P,.
b)
For each door, the seal leakage rate is
- 5 scf per hour when the gap between the door seals is pressurized to 2 10 psig.
- e.
The provisions of SR 3.0.3 are applicable to the Primary Containment Leakage Rate Testing Program.

Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.12 Safety Function Determination Program (SFDP)
(continued)
- b.
A loss of safety function exists when, assuming no concurrent single failure, and assuming no concurrent loss of offsite power or loss of onsite diesel generator(s), a safety function assumed in the accident analysis cannot be performed.
For the purpose of this program, a loss of safety function may exist when a support system is inoperable, and:
- 1. A required system redundant to system(s) supported by the inoperable support system is also inoperable; or
- 2. A required system redundant to system(s) in turn supported by the inoperable supported system is also inoperable; or
- 3. A required system redundant to support system(s) for the supported systems described in b.1 and b.2 above is also inoperable.
- c.
The SFDP identifies where a loss of safety function exists.
If a loss of safety function is determined to exist by this program, the appropriate Conditions and Required Actions of the LCO in which the loss of safety function exists are required to be entered.
When a loss of safety function is caused by the inoperability of a single Technical Specification support system, the appropriate Conditions and Required Actions to enter are those of the support system.
5.5.13 Primary Containment Leakage Rate Testing Program This program shall establish 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-Testing Program," dated September 1995 as modified by the following exceptions:
- 1.
NEI 94 1995, Section 9.2.3: The first Unit 1 Type A test performed after June 14, 1994 Type A test shall be performed no later than June 13, 2009.
