January 12, 1999 Duke Energy Corporation ATTN:
Mr. W. R. McCollum Vice President Oconee Site P. 0. Box 1439 Seneca, SC 29679
SUBJECT:
MEETING
SUMMARY
- OCONEE NUCLEAR STATION (ONS)
Dear Mr. McCollum:
This refers to the meeting that was conducted by mutual request at the Nuclear Regulatory Commission Region II office on December 8, 1998, to provide an update to the Oconee Recovery Plan and related plant performance. Enclosed are a list of meeting attendees and your presentation handout.
It is our opinion that this meeting was beneficial, resulting in the following understandings: (1)
Duke Energy Corporation's Nuclear Assessment and Issues Division will independently assess if the intended goals of the Oconee Recovery Plan have been met; (2) Oconee will be phasing in a 1999 Improvement Plan; and (3) the regularly scheduled bimonthly meetings between NRC and Oconee to discuss Management Oversight Group activities and plant performance will be extended to the Spring due to observed performance improvements at Oconee.
In accordance with Section 2.790(a) of the NRC's "Rules of Practice," Part 2, Title 10, Code of Federal Regulations, a copy of this letter and its enclosures will be placed in the NRC Public Document Room.
Should you have any questions concerning this meeting, please contact Mr. R. Carroll at (404) 562-4511.
Sincerely, Original signed by:
Charles A. Casto Deputy Director Division of Reactor Projects Docket Nos. 50-269, 50-270, 50-287 License Nos. DPR-38, DPR-47, DPR-55

Design Basis Initiatives - CRVS Nud Completed:
Control Room boundary sealing has been improved (for pressurization).
Control Room Ventilation System (CRVS) Ductwork Sealing has been performed to reduce unfiltered in-leakage into the CRVS Single Failure of Unit 1 and 2 Cable Equipment Rooms has been corrected by installation of a modification.
Tracer gas testing has been performed on the ONS Unit 1 &2 Control Room and the Unit 3 Control Room and results of the testing have been incorporated into current operator dose calculations.
Current Status Current test results indicate Unit 1 and 2 CRVS can maintain 1/8" positive pressure with the worst case single failure.
Unit 3 CRVS meets 1/8" criteria with all zones EXCEPT Outside.
A Design Study is underway to upgrade operator dose calculations and determine modifications to the CRVS to improve operator protection during accident scenarios.
Planned:
Additional Ductwork Sealing will be performed on Unit 3 with the intent meeting 1/8" pressurization criteria with respect to ALL zones.
ONS will meet with the NRC once the CRVS Design Study is complete to discuss results and future plans.
CRVS Equipment will be included in the scope of the QA-5 Program. Work is currently underway to determine equipment scope to include.

Design Basis Initiatives Keowee ES Test Reason:
Collect data to evaluate the alternatives of Keowee loading -60% voltage/frequency (current design) and -90% voltage/frequency (new design being considered)
Method:
Two tests simulating LOCA/LOOP emergency loading on Keowee underground path.
The -90% test was done first with a temporary modification installed on Keowee Unit 2 to delay loading. The -60% test was then conducted to collect data under the same load and source conditions so that valid comparisons could be made.
Test Execution:
Each test was conducted successfully and sufficient data was collected to allow detailed analysis Results:
Analysis of the data will take approximately 2-3 months at which time a decision will be made on the most effective loading scheme for the LOCA/LOOP scenario. Results will be shared with the NRC.
