NUCLEAR REGULATORY COMMISSION

SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION RELATED TO AGING EFFECTS
OF INSULATED CABLES AND CONNECTIONS FOR THE OCONEE
NUCLEAR STATION, UNITS 1, 2, AND 3, LICENSE RENEWAL APPLICATION
(LRA)
Dear Mr. McCollum:
The Nuclear Regulatory Commission issued inspection report 50-269/99-12, 50-270/99-12, and
50-287/99-12 on September 21, 1999. The purpose of that inspection was to determine whether
your aging management programs adequately support your application for renewed operating
licenses for Oconee. One of the inspection findings identifies an issue related to applicable
aging effects for insulated cables and electrical connections that conflicts with the staffs findings
in the safety evaluation report (SER) that was issued by the staff on June 16, 1999, regarding
the Oconee license renewal application.
The staff concludes that the results of the inspection need to be reflected in a change to the SER
sections related to insulated cables and connections. Furthermore, the staff will need
additional information in order to resolve this issue. The Oconee license renewal application
(Section 3.6.3) identified the service environments in which insulated cables and connections
operate in as 'thermal', 'radiation', and 'moisture'. The application concluded that based on the
review of industry information, NRC generic communications, and Oconee operating experience,
no aging effects are applicable for insulated cables and connections. Therefore, no aging
management program is necessary. The NRC inspection team conducted walkdowns inside and
outside of containment to assess the material condition, reviewed a sample of the results of
previous Duke electrical inspections and problem investigation process reports and, found that
there is evidence of aging of insulated cables and electrical connectors, that appear to warrant
an aging management program. Therefore, Duke is requested to provide the technical basis for
the conclusion that no aging management program is needed or, provide a description of the
J
aging management program that will be utilized for insulated cables and connections at Oconee.
/
This issue is designated as Open Item 3.9.3-1 for tracking purposes.
As you are aware, the staff is currently scheduled to issue an update to the Oconee license
renewal application SER by February 12, 2000. The schedule also shows that you will respond
to all SER open items by October 15, 1999. Although the staff does not expect you to respond
to the above request for additional information by October 15, 1999, we would appreciate a
schedule for when you intend to respond to the issue.

Currently the staff has not identified any other items in the inspection report that fundamentally
call into question the findings in the Oconee license renewal application SER. However, the
regional and headquarters staff will work with you to identify and develop a closure plan for all
the issues in the inspection report. If during the course of this activity the staff identifies other
issues where it needs additional information in order to update the SER we will inform you in a
separate letter.
If you have any questions regarding this issue please contact me at 301-415-1183, or the project
manager for the Oconee license renewal application, Mr. Sebrosky, at 301-415-1132.
