RETURN TO A. MachEn FCTC: RHO SEP 3 01985 396-83 71-9071 ANEFCO. Inc.

ATTN: Dr. John D. Murphy, Sr.

P.O. Box 433 Ridgefield, CT 06877 Gentlemen:

This refers to your application dated August 13, 1985, requesting approval of a supplementary shield for the flodel No. AP-101 cask.

In connection with our review, we need an analysis denenstrating the 1

proposed shield remains effective under norral and accident conditions of transport (10 CFR 5571.47 and 71.51(a)(2)). Your letter of August 13 was not responsive to our letter of July 12, 1985. The various drop orientations were not taken into account for nornal and accident conditions of transport. The supplemental shielding is directional in its effectiveness, this is an unacceptable practice. The shoring used to support the supplemental shielding has not been shown to damage the inner cavity walls under normal conditions of transport.

The additional information requested by this letter should be submitted in the form of a new application within 60 days from the date of this letter. If you have any questions regarding this ratter, we would be pleased to meet with you and your staff.

Sincerely,

,am ey htim/S E '#
