Subject:

Certification of Westinghouse Hittman Nuclear Incorporated HN-100 Series 3 Cask Certificate of Compliance No. 9151, Rev. 6

Dear Mr. MacDonald:

It is requested that the referenced Certificate of Compliance be amended. Enclosed are eight (8) copies of the following for your review:

(1) Hittman Drawing Numbers:

C001-5-9139, Rev. 8 C001-5-9143, Rev. 8 The drawings listed above have been revised to incorporate two minor changes resulting from our recent fabrication of an HN-100 Series 3 cask. The revision to C001-5-9139 (Zone B-6) involves a tolerance change

$g on the gap dimension between the inner and outer shells. The minimum g@ lead thickness required by our design and the Safety Analysis Report (SAR) so is not affected. The revision to C001-5-9143 (Zone D-4)~ involves a change O$

to the weld symbol called out earlier. Due to close clearances and welding o

(D o equipment access, a groove weld is more readily accomplished here. The eg optional weld has a strength equal to the original fillet weld. No impact

@c tc the SAR occurs.

oo Y

The amount of $150 for administrative processing of the requested

@g revision is currently on deposit with you under Dotket No. 71-9151.

oo G 0.0 It is noted that the attached documents are stamped " PRO-PRIETARY" and bear notices relative to the further dissemination of this information. Hittman has no objection to the filing of this material in the Nuclear Regulatory Commission Public Document Room, provided that the notices remain in the file with this material.
