Subject:

Resolution of Containment Vent and Purging Technical Specifications -

Joseph M. Farley Nuclear Plant Units 1 and 2

) '

By letter dated January 17, 1986, you provided a supplement to your letter dated April 19, 1985, relating to the subject of this letter. After further discussions between the Alabama Power Company staff and the Comission staff, we have agreed that you should propose finalizing the Farley Units 1 and 2 Technical Specifications at your earliest convenience. The enclosed Technical Specifications, which we have modified after discussion and agreement with your staff, are found acceptable.

We consider this action will close out the Multiplant Action B-24 Technical Specifications, will resolve Farley Unit 2 License Condition 2.C(17), and will permit the continued use of the 8-inch mini-purge system. The system may be used for safety related reasons without a time-limit restriction, but with enhanced surveillance requirements and with new action requirements.

Sincerely,

/s/

Edward A. Reeves, Project Manager PWR Project Directorate #2 Division of PWR Licensing-A Office of Nuclear Reactor Regulation

Enclosure CONTAINMENT SYSTEMS CONTAINMENT VENTILATION SYSTEM LItilTING CONDITION FOR OPERATION 3.6 .1.7 Containment purge supply and exhaust valves shall be OPERABLE

• and:

a. The 48-inch containment purge supply and exhaust isolation valves (CBV-HV-3198A,3198D,3196,3197) shall be de-activated and secured in their closed position,

b. The 8-inch containment mini-purge supply and exhaust isolation valves (CBV-HV-2866C, 2866D, 2867G, 28670) may be open for safety-related reasons.

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

n.

1. Reduce the leakage to within the limit, or

2. Isolate containment purge supply or both supply and exhaust penetrations as required to reduce the leakage rate from the containment atmosphere to the outside atmosphere to within the limit of Specification 4.6.1.7.2 by the use of at least:

a) one operable de-activated 48-inch inside containment purge supply or both supply and exhaust isolation valves secured in the closed position or secured by use of a blind flange, and one operable de-activated 8-inch inside containment purge supply or both supply and exhaust isolation valves secured in the closed position or secured by use of a blind flange, or
