Dear Mr. Chappell:
Enclosed please find a consolidated application for the Amersham Model 650 Type B(U) package. We request that the changes indicated in this application be incorporated into the NRC certificate of compliance number 9032.
This consolidated application will assure that all changes that have been made to the shipping package since the original approval as a Type B package are reflected on the current certificate. The application has been updated to show compliance with the 1985 IAEA Transport regulations which is required for both international and air shipments. We request that the application be reviewed for compliance to the 1985 IAEA regulations.
A list has been included to indicate the changes made to the submission that is currently on file at NRC. Where applicable, we have shown the justification for the changes made in the submission. We appreciate your assistance with this effort to assure the information submitted in support of this package is accurate and up to date. Please contact me if you require any additionalinformation.
Sincerely, b
o Cathleen Roughan Regulatory Affairs Manager

I Amersham Corporation recently determined, that it was necessary to bring the Model 650 Safety Analysis Report (S.A.R.) into line with'the current USNRC I
Part 71 and IAEA Safety Series No.
6, 1985 Edition (as amended) Regulatory Standards.
l It must be emphasized, that no changes have been made to the product, as part of this effort, and thus, there is no impact on the ability of the Model 650 to continue meeting the Safety Requirements.
i 1
The changes that have been made to the S.A.R.,
affect most of the pages of the report and therefore, it is required, that the revised report replace l
the existing report in its entirety.
l l
The changes made to the report accompanying this aetter fall into two
' categories.
l A)
Those changes that are considered to have no impact on the technicalities of the product or the Safety Standards.
B)
Those changes that result from the restructuring of the format and i
certain technical changes that resulted from checking all weights l
and measures.
i Items falling into Category A are not discussed herein, they are identified as follows:
1)
A uniform approach to the presentation of weights and measures within the S.A.R.
text has been adopted. American has been selected as primary with Metric as secondary.
2)
Correction for spelling, typographic and minor grammatical errors.
3)
American dimensions have been converted from decimals to fractions where appropriate.
~
Items falling into Category B, are identified location wise herein and are described as follows:
1)-
Those changes that reflect the restructuring suggested by Revision 2 of the Regulatory Guide 7.9 and IAEA Safety Series No. 6 1985 Edition (as amended).
2)
Those changes to weights and measures, resulting from a direct comparison, between current product detail / assembly drawings,-from which the product is manufactured, S.A.R. Descriptive Drawings and the physical product.
Or, the correction of calculative. errors.
l
?
3)
The depth of the minimum weld penetration on the containment Capsules has been changed for added conservatism, from.020 inches i
(0.51 mm) to.016 inches.(0.41 mm).
This has impacted the results of certain stress calculations.
In addition to those changes that fall into categories A & B.
It is;to i
be noted, that all drawings and Certificates of Compliance listed in Sections l
1.3 and 2.10 have been replaced where necessary with the latest revision.
- l i
Also, Chapter 7-hac been completely revised to remove all reference to 1
Operational Instructions and to relocate the Maintenance Instructions (revised) to Section 8.2 Appendix A.
The
- Table of Contents' was restructured to reflect the suggested requirements of Revision 2 of the Regulatory Guide 7.9.
