ARKANSAS POWER & LIGHT COMPANY

)
)
EXEMPTION I.
The Arkansas Power and Light Company (the licensee) is the holder of Facility Operating License No. NPF-6 which authorizes operation of Arkansas Nuclear One, Unit No. 2 (ANO-2). This license provides, among other things, that it is subject to all rules, regulations and Orders of the Commission 1
now or hereafter in effect.
The facility uses h Combustion Engineering, Inc. pressurized water reactor l
at the licensee's site located,in Pope County, Arkansas.
II.
Section 50.48(c)(3) of 10 CFR 50 requires that certain features of the facility fire protection program, specifically those that involve installation of modifications which can be effected only during an outage, shall be imple-mented before startup after the earliest of the following events commencing 180 days or more after February 17, 1981:
(1) The first refueling outage; (2) Another planned outage that lasts for at least 60 days; or (3) An unplanned outage that lasts for at least 120 days.
For ANO-2, the Commission granted, on May 10, 1982, an exemption with respect to the requirements of 10 CFR 50.48(c)(3). The exemption extended the date, February 17, 1981, from which the installation schedules established in 10 CFR 50.48(c)(3) are calculated, to July 1, 1982.

By letter dated July 1, 1982, the licensee requested an exemption from the 50.48 schedular requirecent, dekaying the modification of the switchguar in Fire Zones 2100-Z and 2101-AA from the completion of the refueling outage, 2R3, which began in October 1983, to the completion of the subsequent outage, 2R4, expected to begin in July 1985. The delay is necessitated because of the long procurement lead time required in getting the switchgear equipment from the vendor.
By letter dated September 27, 1983, the licensee informed the staff that it had made a substantial effort to have the switchgear equipment delivered and installed during the 2R3 outage, thus eliminating the need for a schedular exemption..However, the licensee encountered an unanticipated problem in that the vendor was pla,nning to manufacture the switchgear equipment at a facility which was not on the licensee's Qualified Vendor List. This would have resulted in the licensee performing a detailed and time, consuming Quality Assurance audit of the facility in question to ensure the equipment met the licensee's Quality s
Assurance Standards. Diligent negotiation, which was concluded in mid-August 1983, resulted in the manufacture of the equipment at a facility on the licensee's Qualified Vendor List.
However, delivery of the switchgear equipment is not expected until late January 1984.
Thus, the equipment would not be re-ceived in time to be installed during the current refueling outage, as required by 10 CFR 50.48(c).
The licensee stated in a letter dated July 13, 1983 that the affected fire zones are all equipped with ionization type smoke detectors which alarm in the control room to provide early fire detection capability and that the additional fire preventive measures are provided by the licensee's Auxiliary Operators, who routinely walk through these zones during the performance of their duties.
I
Based on the above considerations, we find that the licensee has made a good faitn effort to complete the modification during the current outage as required by 10 CFR 50.48(c).
We find that the licensee encountered an unanticipated procurement problem and that the delivery of the equipment will not be made in time to effect the modification.
We also find that, because of the fire preventive measures already provided for the affected fire zones,.
there is no undue risk to the health and safety of the public involved with.
continued operation until the completion of this modification during the 2R4 refueling outage. Therefore, we conclude that the licensee's request for an extension of the completion date required by 10 CFR 50.48(c)(3) should be granted.
III.
Accordingly,theCommissionhasdeterminedthat,pursuantto10CFR 50.12, an exemption is authorized by law and will not endanger life or property or the common defense and security, is otherwise in the public interest, and is hereby granted.
The Commission has determined that the granting of this exemption will not result in any significant environmental impact and that pursuant to 10 CFR 51.(d)(4) an environmental impact statement or negative declaration and environmental impact appraisal need not be prepared in connection with this action.
This Exemption is effective upon issuance.
