& Material Safety U. S. Nuclear Regulatory Commission Washington, D.C. 20555

Reference:

Docket No. 71-9096

Dear Mr. MacDonald:

We are submitting herewith a consolidation of the application and Safety Analysis Report for the CNSI Model No.21-300 shipping cask. This submittal supersedes in their entirety all references listed in Certificate of Compliance No. 9096, Rev. 2 dated April 6,

[%)

1979.

With this submittal we are including eight (8) copies of Revision J to Drawing No. 1-298-101, which supersedes Revision H.

Appendix 1 to this letter identifies significant drawing changes, none of which affect the safety of the package.

As noted in Zones F-3 and F-5 of Drawing No. 1-298-101, Rev. J, we propose to change the primary and secondary lid gasket materials and dimensions as called out in items 16 and 14 respectively. These gasket arrangements have been fully tested at our Barnwell facility and they provide a far better seal chan the original design.

Also with this submittal we are including eight (8) copies Revision A to Drawing No. 1-298-101A which calls out the dimensional change of the pallet slots from two (2) inches to six (6) inches. This change is required to accommodate the larger lifting lugs and the rigging for the liners. This change does not reduce the effectiveness of the load distribution pallet.

Section 2.6.3 of the enclosed consolidated Safety Analysis Report addresses the proposed change in the torque value for the primary and secondary lid bolts. You will note _that since the pressure load is significantly below the preload, gasket preload will remain intact.

O v

16075:/

g In Section 2.3 of the Safety Analysis Report and as noted in the enclosed Drawing No. 1-298-101, Rev. J, we propose to use ASTM A516 Grade 70 steel in the fabrication of all future model 21-300.

This steel will be normalized and tested using a Charpy Impact Test to meet impact requirements of ASTM Class 1 specification.

ASTM A516 Grade 70 is a better quality material construction with improved ductility at ambient temperatures to - 400 F and will surpass the existing specifications for approved packages fabricated from other materials. A copy of the specifications for this steel is enclosed.

In accordance with the provisions of Section 170.31 (ll)(c) of 10CFR 170 we are enclosing our check in the amount of $690.00 as payment for a minor amendment.

Your cooperation in expediting your approval of this request w'ould be greatly appreciated.

Please contact this office if you have any questions.

Sincerely, CHEM-NUCLEAR SYSTEMS, INC.

Docket No. 71-9096 l

APPENDIX 1 A summary of revisions to Drawing No. 1-298-101 Rev. H to Rev. J are as follows:

1.

Section views B-B and C-C have been relocated.

2.

In Zone G-4 and'76 7/8 t 1/16 dimension was removed and the 0

1/8" gap call-out was added for clarification.

3.

In Zone E-8 the note was revised to require that mounting holes be located using a template. This change facilitates the securing of any cask on any trailer.

4.

In Zones B-4, G-4 and B-6 weld size is noted.

5.

In Zones G-2, F-2, B-5, G-3 and B-4 weld call-outs are changed for ease of fabrication and to upgrade welds.

6.

In Zone A-4 flag notes 3 and 4 are removed eliminating confusion with notes 6 and 7.

7.

In Zone B-4 detail 16 is removed and detail 29 is added due to change of gasket design.

s 8.

Parts List items are revised as follows:

A.

Item 22 - dimensions changed to match body shell.

B.

Item 34 - finalized as-built dimensions.

C.

Item 29 - dimensions changed for ease of lid installation.

D.

Item 12 and 19 - added ASTM Equivalent Spec.

I E.

Item 3 - eliminated option of 1/8" thick.

F.

Items 39 and 40 added for clarity.

4 G.

Item 14 and 16 - revised gasket dimensions and material.
