g JOSEPH M. FARLEY NUCLEAR PLANT - UNIT 2 Extension Request for License Condition 2.C.(21)(c)

Gentlemen:

In accordance with the requirement of the Parley Nuclear Plant Unit 2 Operating License [NPF-8, Section 2.C.(21)(c)],

Alabama Power Company is committed to complete all modifica-tions, prior to April 1, 1982, to assure access to vital areas and protection of safety related equipment following an accident resulting in a degraded core. The commitment date was based on a two week turbine-generator inspection and maintenance outage originally scheduled for the spring of 1982 and expected material ship dates, which would allow the completion of this license condition.

In previous letters dated January 14, 1981; February 9, 1981; February 18, 1981; and February 23, 1981; five major modifications were described to satisfy the above commitment.

Presently, four of these modifications have been completed.

The final modifications, associated with the electrical penetration room, involve the installation of electrical disconnects, described in the February 23, 1981 letter, in a vital area which would allow power to be restored to eight motor operated valves during the post-accident conditione, and the shielding of the electrical penetration room door to support access of personnel obtaining post-accident RCS samples. Complete design specifications for the electrical disconnects were developed and procurement was expeditiously initiated on April 15, 1981, in a manner to support the aforementioned schedule. The design of the shielding for the Egt d electrical penetration room door was not finalized until \Ag' October,1981 due to dif ficulty in providing a seismically supported shield weighing approximately eighty-five hundred pounds which can be moved to facilitate access for normal operations and maintenance. Procurement was initiated \

immediately upon design completion. \o0 g,\\

Since the time of the original commitment and scheduling of the turbine generator outage, an unforeseen forced outage has occured on January 31, 1982. The presently expected ship 8202180139 820211 PDR ADOCK 05000364 F PDR

Director, Nuclear Reactor Regulation February 11, 1982 Attention: Mr. S. A. Varga Page 2 date of the electrical disconnects, which has repeatedly slipped, is late February, 1982. The present outage is scheduled to be completed by February 14, 1982, which is prior to the present ship date of the disconnect devices. These disconnects can only be installed during an outage when the unit is placed in cold shutdown. Work originally planned for the two week turbine-generator inspection and maintenance outage is currently being completed, thereby, making it unnecessary to schedule any unit outages prior to the first refueling.

The fabrication status of the shielding of the electrical penetration door leads Alabama Power Company to believe the vendor will be unable to satisfy the original ship date of March 1, 1982. As a result, Alabama Power Company has assigned personnel to expedite this shipment. Despite this effort, the delivery of the shield door is not expectc 3 until early April, 1982. Upon receipt of the door, Alabama Power Company will initiate its installation in a timely manner.

Alabama Power Company therefore requests that license condition 2.C.(21)(c) be extended until the first refueling outage or the first extended cold shutdown of sufficient duration to complete this work. Alabama Power Company's Plant Operations Review Committee has reviewed this proposed change to the Parley Unit 2 Facility Operating License NPF-8 and has determined that the change does not involve an unreviewed safety question as shown in the enclosed safety evaluation.

The Nuclear Operations Review Board will review this change at the next scheduled meeting.

The class of this proposed change is designated as Class III according to 10 CFR 170.22 requirements. Enclosed is a check for $4,000 to cover the total amount of fees required.

In accordance with 10 CFR 50.30(c)(1)(1), three signed originals and forty (40) additional copies of this change are enclosed.

Yours very truly,

SAFETY EVALUATION'FOR EXTENSION OF UNIT 2 LICENSE CONDITION 2.C.(21)(c)

I. Background Alabama power Company was required by Unit 2 operating license condition 2.C.(21)(c) to complete by April 1, 1982, all modifications to assure access to vital areas and pro- i tection of safety equipment following an accident resulting in a degraded core. The commitment date was based on a two week turbine-generator inspection and maintenance outage originally scheduled for the spring of 1982 and expected material ship dates, which would have allowed the completion of this license condition.

II. Reference Facility Operating License No. NPF-8, license condition 2.C.(21)(c).

III. Basis l A. Introduction l

l Five major modifications are necessary to satisfy the requirements of NUREG-0737, Item II.B.2; four of the modifications have been completed. The final modifications, associated with the electrical penetration room, involve the installation of electrical disconnects, described in the February 23, 1981 letter, in a vital area which would allow power to be restored to eight motor operated valves during the l post-accident conditions, and the shielding of the

( electrical penetration room door to support access of personnel obtaining post-accident RCS samples.

Complete design specifications for the electrical disconnects were developed and procurement was expeditiously initiated on April 15, 1981, in a manner to support the aforementioned schedule. The design of the shielding for the electrical penetration room door was not finalized until October,1981 due to difficulty in providing a seismically supported shield weighing approximately eighty-five hundred pounds which can be moved to facilitate access for normal operations and maintenance. Procurement was initiated immediately upon design completion.

Since the time of the original commitment and scheduling of the turbine generator outage, an unforeseen forced outage has occured on January 31, 1982. The presently expected ship date of the electrical disconnects, which has repeatedly slipped, late February, 1982. The present outage is scheduled

scheduled to be completed by February 14, 1982, which is prior-to the present ship date of the disconnect devices. These disconnects can only be installed during an outage when_the unit.is placed in cold shutdown. Work originally planned for.the two week turbine generator inspection and maintenance outage is currently being completed, thereby, making it unnecessary to schedule any unit outages prior to the first refueling.

The fabrication status of the shielding of the electrical penetration door leads Alabama Power Company to believe the vendor will be unable to satisfy the original ship date of March 1,1982. As a result, Alabama Power Company has assigned personnel to expedite this shipment. Despite this effort, the delivery of the shield door is not expected until early April, 1982. Upon receipt of the door, Alabama Power Company will initiate its installation in a timely manner.

B. Conclusion t

l This does not significantly increase the risk of inability to operate the plant safely. The probability of an accident which results in a degraded core and requires that power be returned to these valves and post-accident RCS sampling, both in a high radiation environment, for a period of less than one fuel cycle is extremely small. Consequently, Alabana Power Company requests that license condition 2.C.(21)(c) be extended until the first refueling outage or the first extended cold shutdown of sufficient duration to perform this work. Therefore, extending this license condition requirement until the first refueling outage will not have a significant impact on the safe operation of Farley Unit 2. This proposed change to the license does not constitute an unreviewed safety question as defined by 10 CFR 50.59.
