Oconee Nuclear Station Docket Nos. 50-269, -270, -287 i
Dear Mr. Moseley:
The Babcock and Uilcox Company has informed us of a deficiency in the design of the internals handling fixture spherical nut retaining devices in use at Oconee Nuclear Station. Attached is a B&W report documenting their generic investigation of this deficiency.
Modification to the spherical not retaining device has been completed on Oconee Units 1, 2, and 3.
This modification consists of attaching a plate to the bottom of the threaded rod to prevent the spherical nut unthreading.
Very truly yours, W
