CERTIFICATE OF COMPLIANCE # USA /9151/A, REVISION
/
SUBMITTAL
Dear Mr. MacDonald:
This is to request a revision to the current NRC Certificate of Compliance 9151 (Rev. 12) to revise the following:
1)~
In Certificate of Compliance paragraph 7 (b),
change the.
revision of "LN Technologies" leak test procedure WM-011 to L
Rev..H from Rev. Gs 2)
Identify the owner of both the HN100 Series 3 and LN14-170 l-Series I_as Scientific Ecology Group, Inc. (Leave cask names t
.as is.for now).
Wo.make the first request to resolve an administrative problem identified in-house.
That is, the-current Certificate of Compliance references the leak test procedure WM-011 at revision
.G.-' Revision.H, which added two minor items, has been distributed
.and used in the field for some time.
To simply recall the later revision ignores its' long use in the field and at LN Technologies.
Both revisions of the leak test procedure and the change notice
'that describes the two minor additions are included for your review.
In the procedure Section 6.3, a leak test solution equivalent to the solution already listed in revision G was added.
Specifically naming this solution, which is very common in power' plants, facilitates operations at these sites.
The other change involves adding the test gauge range and serial
'1
' number to the test report form and procedure text, respectively, for consistency.

Mr. Charles E. MacDonald July 5, 1990
-Page 2 SEG polled its Operating Review Committee members who concurred that these changes have-no impact on the level of safety afforded the user or the public.
SEG has also generated a nonconformance report to address this discrepancy.
We have ident,111ed no similar deviations with our other cask Certificate of Compliances.
to facilitate To reduce the potential for problems as above and.
(HN100 operations, we had planned to combine the two. cask models Series 3 and LN14-170) into one.
We will submit to you within the month the related details.
Change number two described above could be accomplished now or at the later revision, at your discretion.
Enclosed herewith-is our application fee check for One Hundred Fifty Dollars
($150.00).
As usual, the documentation submitted herewith is proprietary to SEG but may be filed in the NRC PDR per NRC policy.
Please call me at anytime if you have questions regarding this request.
