Alabama Power Company 600 North 18th Street Post Office Box 2641 Birmingham, Alabama 35291-0400 Telephone 205 250-1835 AlabamaPower R. P. Mcdonald thesouthemelectncsystem Senior Vice President 10CFR50.90 May 4, 1987 Docket Nos. 50-348 50-364 U. S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, D.C. 20555 Gentlemen:

Joseph M. Farley Nuclear Plant . Units 1 and 2 Containment Vent and Purging Technical Specification Changes By letter of June 19, 1986, the NRC provided proposed Technical Specification pages determined by the.NRC to be acceptable to resolve and close out Multiplant Action B-24 and Farley Unit 2 License Condition 2.C.(17). These changes add a quarterly surveillance requirement to detect major degradation in the 8-inch and 48-inch containment purge supply and exhaust isolation valve penetrations. In addition, the leakage rate for each containment purge supply and exhaust penetration will be verified to be less than or equal to 0.05 La prior to startup after each Cold Shutdown if not performed in the previous 92 days. The proposed Technical Specification changes are provided in Attachment 1. These changes conform to the intent of the June 19, 1986 proposed Technical' Specification pages and deviate only in an editorial rewrite intended to clarify the Action Statement and Surveillance Requirements of Specification 3.6.1.7.

Two editorial revisions are also provided with this submittal involving Containment Ventilation System Technical Specification's bases in order to make the two units' Technical Specifications identical. Unit 1 page B 3/4 6-2 is changed to reflect the as built design of the plant utilizing 8-inch in lieu of 18-inch purge supply and exhaust isolation valves, to utilize Unit 2 terminology of "in MODES above COLD SHUTDOWN," and to incorporate reasons for safety-related containment venting during operation. These changes are consistent with the Technical Specification provided to Alabama Power Company by the NRC N f gp 5 eA* /p5h

D U. S. Nuclear Regulatory Commission May 4, 1987 Page 2 under Unit 2 License Amendment. Number 34, issued May 17, 1984. - lhe Unit 2 page B 3/4 6-2 discussion of safety-related reasons for containment venting was moved to page B 3/4 6-2a to be consistent with the format of the Unit 1 Technical Specifications.

The purpose'of the quarterly degradation tests of the isolation valves in the containment purge supply and exhaust lines per Specification 4.6.1.7.2 is to identify' excessive degradation of the resilient seals for these valves. In addition, these degradation tests are not subject to the requirements applicable to 10CFR50 Appendix J testing but are to be utilized to provide reasonable _ assurance that at least one set (inside containment or outside containment) of isolation valves provides a sufficient barrier to containment leakage. These degradation tests do not replace Appendix J testing, but are performed in addition to the Type C tests required by Appendix J. Type C testing that is conducted pursuant to Specification 4.6.1.7.3 will conform to the requirements of Appendix J. Failure to satisfy the containment purge supply and exhaust isolation valve leakage rate specifications while in MODES 1-4 will be governed exclusively by the Action requirements of Specification 3.6.1.7 and not by other specifications. The 12-hour time limit in Action Statement b provides the necessary time to confirm that containment integrity exists or to take appropriate corrective action. Isolation of a penetration with leakage in excess of the limit by use of an operable valve or a blind f1ange allows maintenance to be performed on the inoperable valve in that penetration.

Action Statement b.2 requires a determination be made that the leakage rate from the containment atmosphere to the outside atmosphere is less than or equal to the margin available to 0.60 La; however, it'does not require quantification of the leakage.

l Alabama Power Company has determined that the proposed changes do not

involve a significant hazards consideration. In accordance with 10CFR50.92, i

a significant hazards evaluation is provided as. Attachment 2.

Implementation of the proposed Technical Specification changes is requested to commence the first refueling outage of each unit after NRC approval to allow for verification of the adequacy and accuracy of test procedures required to support the additional surveillances.

Alabama Power Company considers NRC acceptance of these Technical Specification changes with normally open minipurge valves and no operational limit goals stated or implied to completely resolve and close out Multiplant Action B-24, Farley Unit 2 License Condition 2.C.(17), NUREG-0737 Item II.E.4.2 and _ all other current open issues of the NRC regarding Farley Nuclear Plant's use of a continuous minipurge system. Resolution of the Containment Vent and Purging issue by the NRC in the manner stated above is considered by Alabama Power Company to render the April 19, 1985 position for initiation of the backfitting procedures as no longer necessary.

Alabama Power Company's Plant Operations. Review Committee has reviewed these proposed changes and the Nuclear Operations Review Board will review these proposed changes at a later.date. Pursuant to 10CFR170.21, the required License Amendment Application. Fee _of $150.00 is enclosed. A copy of these

. proposed changes has also been sent to Dr. C. E. Fox, the Alabama State Designee, in accordance with 10CFR50.91(b)(1).
