ENCLOSURE CONTAINMENT SYSTEMS CONTAINMENT AIR LOCKS LIMITING CONDITON FOR OPERATION 3.6.1.3 Each containment air lock shall be OPERABLE with:

a. Both doors closed except when the air lock is being used for normal transit entry and exit through the containment, then at least one air lock door shiill be closed, and

b. An overall air lock leakage rate of~ 0.05*La at design pressure (47.0 psig).

APPLICABILITY: MODES 1, 2, 3 and 4 ACTION:

With an air lock inoperable, restore the air lock to OPERABLE status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

4. 6.1. 3 Each containment air lock shall be de1TDnstrated OPERABLE:

a. *By pressurizing the vo 1ume between the airlock door gaskets to

> 10.D psig and checking for an extrapolated** seal leakage rate equal to or less than 0.01 La.

1. After each opening, except when used for rrultiple entries, then at least once per 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

2. After performing maintenance which could affect the airlock door gaskets sealing capability.

3. Prior to establishing containment integrity,

b. By conducting an overall air lock leakage test at design pressure (47.0 psig) and verifying the overall air leakage rate is within its limit:

1. At least once per six nonths #.

2. Prior to establishing containment integrity when maintenance that could affect the airlock sealing capability was performed and the maintenance affects components other than the ooor gaskets 1

• and

c. At least once i)er 6 rronths by verifying that only one door in each air lock can be opened at a time.

• Exemption to Appendix 11 J 11 of 10 CFR 50.

• • The measured leakage at the test pressure {10 psig) shall be multiplied by an extrapolation factor of 9.1 to determine what the seal leakage flow rate would be if tested at design pressure (47.0 psig). This extrapolated seal leakage rate shall be less than or equal to 0.01 La.

• # The provisions of Specification 4.0.2 are oot applicable.
