SUMMARY
OF SEPTEMBER 4, 1991, DPC/NRC INTERFACE MEETING On September 4, 1991, the NRC staff (including NRR Project Managers and resident inspectors from Oconee, McGuire, and Catawba) met with representatives of Duke Power Company (DPC) at the Oconee Nuclear Station to discuss issues of interest to both NRC and DPC organizations. Meeting attendees are listed in. The agenda for the meeting is provided as Enclosure 2.
DPC opened the meeting with a status report on the Design Basis Documentation Program for all three Duke nuclear stations. Since there had been a number of personnel changes for the NRC, a brief description of the program was included in the presentation. Brew Barron, the Oconee Plant Manager, then provided a brief assessment of the current status of the Oconee station, followed by a description of initiatives undertaken by Oconee in the area of shutdown risk management. Following these presentations, Andy Kugler.of the Generic Communications Branch, NRR, gave a very informative presentation covering the entire spectrum of NRC generic communications, including sources of information, responsibilities for action, communication vehicles (i.e., generic letters, bulletins, information notices), and NRC tracking and distribution systems.
The final presentation addressed outage planning at Oconee. The meeting concluded with station-specific breakout sessions to discuss licensing issues of interest between NRR project managers, site resident inspectors and DPC compliance engineers. Copies of the slides and handouts used during the various presentations are provided as Enclosure 3.

INTRODUCTION At Oconee, we have learned that the biggest single factor in improving our availability and cutting our cost/KWH is to reduce our outage lengths. This must be accomplished without compromising the quality of the work which must be performed during these outages.
Oconee has completed 35 refueling outages and has gained considerable experience in outage management. Since 1984, outage costs and durations have consistently been reduced while continuing to improve capacity factors. Our last 7 refueling outages were 43, 42, 45, 44, 41, 44 and 44 days respectively.

The capacity factors for these units between refueling outages are 89, 96, 92, 98, 94, 96 and 100 percent, respectively. The average cost of our outages has been less than
$12,000,000. (twelve million dollars).
We believe our success cannot be derived from any one issue by itself, but is a compilation of many factors all complementing each other. We believe however, that there are four key areas which represent our philosophies and can be given the most credit for our successful outages. These areas are:
PLANNING EXPERIENCE TEAM WORK OUTAGE MANAGEMENT
PHILOSOPHICAL ELEMENTS OF OUTAGE PLANNING
- 10 Months -Scope from 5-Year Plan N 8 Months - Revised Outage Scope W 6 Months - All Major Work Defined
- 5 Months - Pre-Outage Plan Issued N
1 Month - Pre-Outage Plan Update Our planning begins with a 5-year plan which is laid out for both outage and non-outage time frames. The 5-year plan begins with our component/system experts identifying their programs for improving performance/reliability of their equipment.
Commitments, preventive maintenance programs, and modifications are also included in the 5-year plan.
Station management meets several times a year to review the 5-year plan and discuss activities that need to be added to or deleted. Removing preventative maintenance from the budget is normally not considered. Generally, during our outages, 70 percent of the work requests performed are for preventative maintenance programs.
Planning for the outage begins 10 months prior to the outage when the first publication of the outage scope is identified to the entire station. The next step is at 6 months prior to the outage. This is the point at which we established the cut off date for additional work items. Any further changes to the outage scope can be made only with the Outage Manager or Station Manager's approval.
N Three UnitSite N Low Personnel Turnover N Shared Maintenance Support 0 Repeat Vendor Support This is an area where we have a significant edge over many other utilities. As stated earlier, we have completed our 35th refueling outage. With 3 units at our station, we learn from mistakes three times faster than a single unit site.
Oconee also has a very low personnel turnover rate with our people having an average length of service of 11 years. This means that the average person at oconee has seen 24 refueling outages in their career.
During the outage we receive support from Duke's ConstructiozVMaintenance Dept.
This organization supports all three nuclear sites along with our fossil and hydro stations. These workers are experienced and well qualified to perform work at a nuclear installation.
For activities which require vendor support, we make every effort to use repeat vendors, secure long term contracts and insist on getting the same people back outage after outage.
0 Team Related Outage Goals N Outage Manager Focal Point N Idea and Experience Sharing
- Collective Success or Failure This is an area that sounds the simplest but is probably the most difficult to accomplish. We emphasize teamwork in the outage goals that we establish and assure that our Outage Manager is the focal point of our team.

1 0
3 DURATION 45 42 38 44 We encourage working together to solve problems and share as many ideas and as much experience as possible. We accept failure as a collective group and work, as a group, toward success.
- Matrix Organization N Shift Manager (STA) Support N Total Plant Focus 0 Short Outage Meetings 0 Management Support The Outage Manager has a Matrix organization of permanently assigned coordinators representing each of the major working groups. Back shift and week end outage management is accomplished by our Shift Managers who are also the Shift Technical Advisors.
During outages, virtually the whole plant focuses its attention on the outage. Our shift maintenance crews are used to maintain the other two operating units.
The outage organization conducts 2 outage meetings a day lasting approximately 30 minutes. During the morning meeting the Plant Manager and all the Superintendents are present. Our meetings are conducted by the Outage Manager. It is understood that it is the Outage Manager's outage and station management support is provided.
Frequent tours of the work sites throughout the outage is conducted by all members of management. Visiting the job site is not only important at the working level, it provides the manager with the level of detail needed to make the right decisions.
OUTAGE ACCOMPLISHMENTS An example of the work completed during a typical outage is as follows:
- 1. Perform work on 700 valves and operators.
- 2. Perform Steam Generator Eddy Current testing and associated work.
- 3. Turbine section disassembly and inspection.
- 4. Electrical inspection of breakers and switchgear.
- 6. Reactor Coolant Pump Motor PM's.
- 7. Containment Integrated Leak Rate Test.
- 8. Complete 30 plant modifications.
- 9. Perform 3600 work requests.
PLANNING Start Early and decide what needs to be done EXPERIENCE Get the same people back outage after outage TEAM WORK The outage belongs to the whole station OUTAGE MANAGEMENT Physical participation by all levels of management Good outages requires four key ingredients:
- 1. PLANNING (Start early and decide as a station what needs to be done)
- 2. EXPERIENCE (When possible get the same people back outage after outage)
- 3. TEAM WORK (No one group is responsible for the outage it belongs to the station)
- 4. OUTAGE MANAGEMENT (Management's physical participation both at the outage meeting and at the job site)
The true measure of a successful outage is not only what it costs or how short it is, but also how well the unit runs between outages.
