Docket No. 50-213

-B14490 Haddam Neck Plant Proposed Revision to Technical Specification May 1993 gg60$DDbK g3 00 P

CONTAINMENT SYSTEMS-CONTAINMENT LEAKAGE LIMITING CONDITION FOR OPERATION 3.6.1.2 Containment leakage rates shall be limited to:

a.

An overall integrated leakage rate of less than or equal to La, 0.18 % 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 Pa, 39.6 psig, or b.

A combined leakage rate of less than 0.60 La for all penetrations and valves subject to Type B and C tests, when pressurized to Pa.

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

ACTION:

With either the measured overall integrated containment leakage rate exceeding 0.75 La or the measured combined leakage rate for all penetrations and valves subject to Types B and C tests exceeding 0.60 La, restore the -

overall integrated leakage rate to less than 0.75 La and the combined leakage rate for all penetrations subject to -Type B and C tests to less than 0.6g La prior to increasing the Reactor Coolant System temperature - above 200 F.

SVRVEILLANCE RE0VIREMENTS 4.6.1.2 The containment leakage rates shall be demonstrated 'at the following test schedule, and shall be determined in conformance with the i

criteria specified in Appendix J of 10 CFR Part 50:

I a.

Three Type A tests (Overall Integrated Containment Leakage Rate) shall be conducted at 40 10 month intervals during shutdown at a pressure not less than Pa, 39.6 psig during each 10-year. service period.

The third test of each set shall be conducted during the shutdown for the 10-year plant inservice inspection; HADDAM NECK 3/4 6-2 Amendment No. J#,
