Reference:

Certificate of Compliance No. 5971, Docket 71-5971

Dear Mr. MacDonald:

The Ceneral Electric Company, Vallecitos Nuclear Center (VNC) holds Certificate of Compliance Fo. 5971 on the Model 1PO-200 shipping container.

The fabrication drawings under which the containers were constructed called for a 1/8-inch groove weld to attach the bottom plate of the cask cavity to the cavity wall. The veld is on the lead side of the cavity and is shown in Certification Drawing No. 129D4758, Revision 1.

VNC wishes to add a 1/8-inch fillet weld between the bottom plate and the cavity wall on the cavity side. The change is shown on Certification Drawing No. 129D4758, Revision 2, enclosed.

-The additional weld will serve two purposes:

(1) the groove-fillet veld combination is superior to a groove veld clone; and (2) the smooth fillet weld surface will facilitate decontamination of the cask cavity.

A check in the amount of $150.00 is enclosed.

If you or your staff have any questions concerning this change, please contact me at (415) 862-4330.

Thank you.

Sincerely,

! _ h.,

G. E. Cunn ngham Senior Licensing Engineer
