3/4.6 CONTAINMENT SYSTEMS 3/4.6.1 PRIMARY CONTAINMENT CONTAINMENT INTEGRITY LIMITING CONDITION FOR OPERATION

==================================================================

3.6.1.l Primary CONTAINMENT INTEGRITY shall be maintained.

APPLICABILITY: MODES 1, 2, 3 and 4. ~~

ACTION:

Without primary CONTAINMENT INTEGRITY, restore CONTAINMENT INTEGRITY within one hour 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 />.

SURVEILLANCE REQUIREMENTS

=================================================.=================

4.6.1.l Primary CONTAINMENT INTEGRITY shall be demonstrated:

a. At least once per 31 days by verifying that:

1. All penetrations* not capable of being closed by OPERABLE containment automatic isolation valves and required to be closed during accident conditions are closed by valves, blind flanges, or deactivated automatic valves secured in their positions, except for valves that are opened under administrative control as permitted by Specification 3.6.3.1.,

and

2. All equipment hatches are closed and sealed.

b. By verifying that each containment air lock is OPERABLE per Specification 3.6.1.3.

• Except vents, drains, test connections, etc. which are (1) one inch norni~a~

pipe diameter or less, (2) located inside the containment, and (3) locked, sealed, or otherwise secured in the closed position. These penetrations s~a~~

be verified closed at least once per 92 days.

( J)JS~fZT A SALEM - UNIT 1 3/4 6~1 Amendment No.

CONTAINMENT SYSTEMS CONTAIN_MENT LEAKAGE LIMITING CONDITION FOR OPERATION

==================================================================

3.6.1.2 Containment leakage rates shall be limited to:

a. An overall integrated leakage rate of ~La, 0.10 percent by weight of the containment air per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at design pressure, ( 47. o psig).

b. A combined leakage rate of ~ 0.60 La for all pene:rations and valves subject to Type B and C tests, when pressu*rized to Pa.

APPLICABILITY: MODES 1, 2, 3 and 4. 1f ~

ACTION:

With either (a) the measured overall integrated containment leakage rate e~ceeding 0.75 La, or (b) with the measured combined leakage rate for all penetrations and valves subject to Types B and C tests exceeding 0.60 La, restore the leakage rate(s) to within the limit(s) prior to increasing the Reactor Coolant System temperature above 200°F.

SURVEILLANCE REQUIREMENTS

==================================================================

4.6.l.2 The containment leakage rates shall be demonstrated at the follows:

a. Type A tests shall be in accordance with 10CFR 50.54 (0) in conformance with Appendix J of 10CFR 50, Option B, using the methods .and provisions of Regulatory Guide 1.163, September 1995 as modified by approved exemptions.

b. Type B and C tests shall be conducted in conformance with Appendix J of 10CFR 50, Option A, with gas at design pressure (47.0 psig) at intervals no greater than 24 months except for tests involving air locks.

c. Air locks shall be tested and demonstrated OPERABLE in convormance with Appendix J of 10CFR 50, Option A, per surveillance Requirement 4.6.1.3.

INSERT A

• A one-time change is granted to have the containment purge supply and/or exhaust isolation valves open in Modes 3 and 4 following the steam generator replacement outage (1R13) . The cumulative time for having the valves open in Modes 3 and 4 is limited to fourteen (14) days. Each valve will be immobilized in the shut position prior to initial entry into Mode 2. The one-time exemption expires with initial entry into Mode 2 following 1R13.
