SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION - OCONEE NUCLEAR STATION, UNITS 1, 2, AND 3 (TAC NOS. MA6157, MA6158, AND MA6159)
Dear Mr. McCollum:
By letter dated July 27, 1999, Duke Energy Corporation requested an amendment to the Oconee Nuclear Station, Units 1, 2, and 3 Technical Specifications. The amendment would incorporate the Keowee Hydro Unit's voltage and frequency protection modification surveillance requirements by adding new Surveillance Requirement (SR) 3.8.1.17. As a result of its review, the staff has determined that additional information is needed in order to continue our review as shown in the enclosure. This request has been discussed with Renee Gambrell of your staff and a response date of October 7, 1999, established.
Sincerely, Original signed by:
David E. LaBarge, Senior Project Manager, Section 1 Project Directorate 11-2 Division of Licensing Project Management Office of Nuclear Reactor Regulation Docket Nos. 50-269, 50-270, and 50-287

SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION - OCONEE NUCLEAR STATION, UNITS 1, 2, AND 3 (TAC NOS. MA6157, MA6158, AND MA6159)
Dear Mr. McCollum:
By letter dated July 27, 1999, Duke Energy Corporation requested an amendment to the Oconee Nuclear Station, Units 1, 2, and 3 Technical Specifications. The amendment would incorporate the Keowee Hydro Unit's voltage and frequency protection modification surveillance requirements by adding new Surveillance Requirement (SR) 3.8.1.17. As a result of its review, the staff has determined that additional information is needed in order to continue our review as shown in the enclosure. This request has been discussed with Renee Gambrell of your staff and a response date of October 7, 1999, established.
Sincerely, David E. LaBarge, Senior Project Manager, Section 1 Project Directorate 11-2

00 REQUEST FOR ADDITIONAL INFORMATION As stated in the submittal, the surveillance requirement (SR) would "verify each Keowee KHU's voltage and frequency out of tolerance logic trips and blocks closure of the appropriate overhead or underground power path breakers. The allowable values shall be as follows:
- a. Undervoltage 12.42 kV
- b. Overvoltage 15.18 KV
- c. Underfrequency 54 hz
- d. Overfrequency 66 hz" The staff requests the following additional information be submitted to allow us to determine that the proposed tests a, e adequate to ensure the operability of the protective relays:
- 1. Either provide an explanation for not including an upper and lower limit for each allowable value or revise the submittal to include such allowable values. Without such limits, the out of tolerance protection could trip Keowee when the tests have shown that the voltage and frequency are not out of tolerance.
- 2. Provide an explanation or revise the submittal to include a requirement to test the allowable value of the timers.
- 3. It is the staff's understanding that the tests may not, if fact, cause the breakers to open if closed or ensure that they cannot be closed if open. Please discuss this aspect of the testing process and how the tests ensure that the SR is satisfied.
- 4. Provide a discussion of how the analytical value was chosen for the frequency and voltage out of tolerance protection. Also, provide a discussion of the uncertainties that were used to derive the allowable values.
