Subject:
Duke Energy Corporation Oconee Nuclear Station, Unit 1,2,3 Docket Nos.
50-269,
- 270, 287 Third Ten Year Inservice Inspection Interval Request for Relief No.01-001 (TAC MB1706)
On April 5,
- 2001, Duke Energy Corporation (Duke) submitted Request for Relief No.
01-01 pursuant to 10 CFR 50.55a(g)
(5) (iii) and 50.55a(g) (6) (i).
This request was for eleven (11) components for which Duke personnel determined it is impractical to meet the volumetric requirements for ultrasonic examination of certain specified welds due to piping/vessel geometry, interferences, and existing examination technology.
The request sought relief to accept the portions of the weld volume that can be practically examined.
Through subsequent discussions with the Staff, Duke has concluded that a portion of the request was confusing and poorly worded.
In order to clarify our request, please replace the existing Section III, "Code Requirement from which Relief is Requested" with the new Section III provided on the attachment to this letter.
If there are any questions or further information is needed you may contact R.
P.
Todd at (864) 885-3418.
Very truly yours,
