Dear Mr. MacDonald:

REFERENCE: Docket No. 71-9094

We respectfully submit our response (Attachment 1) to the questions raised inyour June 24, 1985 letter concerning Model CNS 14-195-H shipping package.

Our response is in the form of revised pages to the Safety Analysis Report(Attachment 2). Pursuant to the suggestion in Regulatory Guide 7.9, we haveidentified revisions by vertical lines in the right margin. We ask that youinsert the revised text into the original document sent to you on fiay 1,1985.

Please do not hesitate to contact us with any questions regarding this matter.

Very truly yours,

Responses to NRC Request For Information dated June 24, 1985 Docket No.71-9094.

Operating Procedures

NRC Comment C.l. The operational steps requiring a cask surveyshould be expanded to specify a radiation surveyincluding a determination of surface con _taminationto assure compliance with 10 CFR 71.47 and 71.87.

CNSI Response A.1 Section 7.1 Step 16 and Section 7.2 Step 11 havebeen added t.o require radiation surveys andremovable costamination surveys.

NCR Coment C.2 Step 8 under 7.2 Loading Procedures for Linersrequires the use of alignment marks to correctlyposition the secondary ~11d onto the primary lid.The packaging drawing should be revised to show therequired alignment marks. It is noted that Section8.0, Tests and Maintenance, also discusses lidalignment marks.

,

CNSI Response A.2 Revision AG has been issued to CNSI Drawing1-189-101 which shows the alignment marks. Thereference to this drawing throughout the SafetyAnalysis Report has been changed to identify thecurrest drawing revision.

NRC Comment C.3. Procedures for receiving and unloading the packageshould include a statement regarding compliancewith the requirements of 10 CFR 20.205.

CNSI Response A.3. A note has been added at the beginning of Section7.3 to require performance of receipt surveys.

ACCEPTANCE TESTS

CNSI Response: Additional units 'of the 14-195-H packaging will not befabricated, and therefore, no further responses are provided to these comments.

2.4.3 tiftina Devices

10CFR 71.45 (a) requires that any lift point be designed witha minimum safety factor of three against yielding when usedto lif t the package in the intended manner. The CNS 14-195package is equipped with two lifting trunnions as shown on ()CNS drawing 1-189-101 Rev AG. The following anaylsis'

therefore evaluates one trunnion subjected to 3 tistsone-half of gross package weight, or a total load of 84,750pounds. This analysis shows that the lifting devices canwithstand 3 times the gross package weight without failure.
