Dear Mr. MacDonald:
It is requested that the certificate of compliance for the subject radio-active materials package be amended to cover the use of nonstructural appurtenances.
Enclosed are eight (S) copies of HNDC drawing number C001-5-9121, Sheet 1, Revision 1, which supplements the drawing referenced in the current certificate of compliance. Attachment A lists the requested changes in the certificate of compliance and the items which may be used on the subject package.

b.
Placard Mounting, (Elevation View and View A-A)
Steel angles with a steel plate as shown on View A-A are welded to the outer shell of the casks.

c.
Lif ting Lug Covers (Detail B)
Bent washers may be welded to the cover of the cask adjacent to the cask cover lifting lugs.
The washers >are used as eyes for lanyards attached to the sheet metal covers which are installed over the cask cover lifting lugs. The metal covers are used to prevent the use of the cask cover lugs to lift the entire cask. The attachments do not affect the structural integri ty of the package, d.
