SUMMARY
OF MEETING HELD ON NOVEMBER 3, 1975, TO DISCUSS A PROPOSED GAS TURBINE EMERGENCY POWER SOURCE FOR THE OCONEE NUCLEAR STATION On November 3, 1975, representatives of Duke Power Company met with the NRC staff to discuss the licensee's preliminary plans to install two gas turbines as an emergency power source for us during prolonged outages of the Keowee hydroelectric plants.
A list of attendees is enclosed.
Significant points are discussed below.
The Oconee Nuclear Station has as its primary on-site source of emergency l
When both of these are un-power the two Keowee hydroelectric units.available, Technical Specifica I

days every 10 years.
The second outage interval, h?vever, has been reevaluated to require The licensee is therefore considering approxmiately 2 months every 6 years.the installation of 2 gas turbines as the Lee Gas Turbines, and which would be run continuously during the 2 month outage of the Keowee hydroelectric units, every 6 years, to provide The licensce's position is that the required sourco of emergency power.
by eliminating the 23 miles cf transmission lines required fo would be an acceptable substitution for the Keowee Units during the 2 month maintenance outages.
The licensee provided the history of operation of the proposed gas turbines.It The ratings of each and the plans for overhaul, testing and installation.
was pointed out that the gas turbines would occassionally be used as peaking units as are the Lee Gas Turbines.
Upon consideration of the licensee's proposed plans, the staff indicated that the main concern was that a two month outage of the Keowee Units would be significantly longer than the interval approved in the current Technical Specifications and that an equivalent source of power woul provided.would be vulnerable to the same accidents as are the Lee Gas Turbines.
The j
N;vemb;r., 1975 licensee indicated that they did not propose to seismically qualify the propor,ed gas turbines and that other environmental considerations such as hurricanes, tornadoes and ice storms had not been considered in their plans to install the 2 gas turbines.
It was therefore recommended to the licensee that further review of their plans be made to determine whether the proposed installation could be qualified to the extent that it would be an equivalent substitution for the Keowce Units or whether they could propose limiting conditions under which the gas turbine installation would be used as a source of emergency power.
It was recommended that the latter alternative take into consideration environmental influences such as hurricane warrnings which would require either shutdown of the Oconee Units or the restoration of the Keowee Units as a normal source of emergency power.
The licensee agreed to conduct a review of their requirements and submit a proposal for the staff's review in the form of an amendment request to the e
Oconee Technical Specifications.
