FOR THE U.S. NUCLEAR REGULATORY COMMISSION e$

U.S. Nuclear Regulatory Commission Transportation Certification Branch Approval Record Model Nos. DT-2, DT-5, and DT-7 Shipping Containers for Type A Fissile Material Docket No. 71-6227 The DOE request for approval of the subject packages dated September 28, 1977 and supplemented November 2,1977 has been reviewed by the staff. The staff concludes that the information provided in support of the approval request adequately demonstrates compliance with the applicable parts of 10 CFR Part 71, subpart C for packaging for Type A fissile material.
The packages are comprised of steel drums with industrial cane fiberboard filling (e.g., celotex), and are used for shipment of uranium as metals, alloys or compounds, enriched to any degree in the U-235 isotope.
f The Model Nos. DT-2 and DT-5 have l8-gage DOT SPEC 17H outer steel drums.
They are 22-1/2-inches in diameter by 33-inches high.
The Model No. DT-7 has a 20-gage D0T SPEC 37A outer steel drum which is 16-inches in diameter by 24-1/2-inches high.
The contents for the Model No. DT-2 is limited to flat uranium plates no larger than 16-inches by 16-inches by 0.4-inches thick. The Model Nos. DT-5 and DT-7 may be used to ship uranium metals or alloys; they have inner containers to contain the radioactive material within the package.
The Model No. DT-7 may be used to ship uranium compounds.
The contents for all three packages are limited to Type A quantities of fissile material. The requirements for such packages are that they satisfy all requirements for normal conditions of transport and that subcriticality is maintained in accordance with the appropriate fissile class for normal and accident conditions.
The contents are solid, and are either non-dispersible or are made non-dispersible by mechanically sealed inner containers. The applicant has determined and reported the minimum transport indexes and-maximum numbers of packages per shipment for each model for Fissile Classes II and III.

. The staff has verified th% criticality results for each package design independently using KEN 0 analyses with the 27 group neutron cross-section set. The staff calculations indicated that subcriticality is maintained for nomal and accident conditions.
~
The staff has not included dry compounds of uranium in the approval for the Model No. DT-5 packaging.
We have determined that a single package remains subcritical as long as the maximum 8.3 kg of enriched uranium compounds (to 100% U-235) is confined to the 2 liter steel inner container.
The application did not identify a specific container; therefore, it could not be demonstrated that the 2 liter container would contain the fissile material under conditions of 10 CFR Part 71.
Although no significant damage would be expected from the normal conditions tests, the Model No. DT-7 was evaluated for a 7% reduction in diameter.
This was done because the applicant did not directly address possible nomal condition damage; they relied on observed minor damage (not quantitatively described) from accident tests to infer that no significant damage from nomal tests would occur. The reduced spacing model was found to be suberitical; since this conservatively limits normal condition damage and infers the behavior of the other models, it was concluded that subcriticality was demonstrated for normal and accident conditions of 10 CFR Part 71.
