Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.15 Safety Function Determination Program (SFDP) (continued)

b. A required system redundant to the system(s) in turn supported by the inoperable supported system is also inoperable; or

c. A required system redundant to the support system(s) for the supported systems (a) and (b) above is also inoperable.

The SFDP identifies where a loss of safety function exists. If a loss of safety function determined to exist by this program, the appropriate Conditions and Required Actions is of the LCO in which the loss of safety function exists are required to be entered.

5.5.16 Containment Leakage Rate Testing proqrarn

a. A program shall be establisl.Jd to implement the leakage rate testing of the containment as required by 10 CFR 50.54(o) and 10 CFR 50, Appendix J, Option B,

as modified by approved e-.emptions. This program shall be in accordance with guidelines contained in Regulatory Guide 1.163, "Performance-Based Containment the Leak-Test Program, dated September 1995." The ten-year interval between performance of the integrated leakage rate (Type A) test, beginning May 4, 1994, for Unit I and April 30, 1993, for Unit 2, has been extended to 15 years.

b. The peak calculated containment internal pressure for the design basis loss of coolant accident, P,, is 47 psig.

c. The maximum allowable containment leakage rate, La, at Pa, shall be 0.10% of containment air weight per day.

d. Leakage rate acceptance criteria are:

1. 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 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 La when tested at > Pa.

b) For each door, leakage rate is < 0.01 La when pressurized to _>10 psig.

e. The provisions of SR 3.0.2 do not apply to the test frequencies specified in the Containment Leakage Rate Testing Program.

f. The provisions of SR 3.0.3 are applicable to the Containment Leakage Rate Testing Program.
