20545 Gentlemen:
This refers to your letter dated December 30, 1977, requesting our additional review and amendnent to NRC Certificate of Compliance No.
6115, dated September 21, 1977, for the Model No. R1010-0032 package to permit shipment of Type B quantities of mixed oxide fuel.
In connection with our review'of this package, we need the information identified in the enclosure to this letter.
Please advise us within thirty (30) days from the date of this letter when this information will be provided.
Sincerely, Original Sicnod by CMMS E. MACDomu,3 Charles E. MacDonald, Chief Transportation Certification Branch Division of Fuel Cycle and Material Safety, NMSS s

i Additional Infomation uested for Review of 1 No. R1010-0032 (71-6115)
Enc 1 to ltr dtd:
1.
Verify the material properties for balsa shown in section 1.3.4.1.
a)
Specify the basa density and any other properties that might-significantly affect pertinent material properties.
b)
Explain why the use of material properties based on the average of high and low density balsa is valid for the safety analysis.
2.
Show how the outer container lid may be considered a continuous member for shear and bending loads, when it is segmented and lap-spliced as shown on Drawing No. R-1010-0038-DD, Rev. 00.
3.
For end or oblique impacts, show that the portion of the impact limiter not directly backed-up or supported by the outer container will remain attached for nomal free drop tests.
4.
Revise the side free drop containment vessel analysis, page A-19, to demonstrate that the deformation of-the protective hood would not cause damage to the containment vessel edge seal.
5.
Revise the top free drop analysis, page A-20..to demonstrate that the containment vessel lid countersunk attachments and bolting lug welds would sustain the apprvpriate impact loads.
6.
Provide an analysis of the packaging for the loads. generated for the corner and oblique 1.upacts.
7.
Provide a more detailed discussion of the puncture tests section i
1.7.2.
This discussion should include a description of the containment i
vessel simulation, the mass distribution compared to the prototype and the points of impact. The statement of results should address j
spanwise bending or beam deformation.

.. 8.
Provide drawings which clearly show all safety related features, particularly the following:
a)
Adequate identification of all materials, including impact limiters;-
b)
All bolts with quantity, materials, and sizes; c)
All we1ds; d)
Grainhirectionofbalsa; e)
All dimensions pertinent to safety; and f)
All components related to safety, e.g., containment vessel 1" end plates.
9.
Show why the packaging should not be limited to shipment by " Air-Ride" motor vehicles only.
10.
Identify and provide a copy of the ANL Test Pmcedure called for in subsection 7.1.3 of Dupont Draft Report DPSPU 75-124-6, October 1975.
