Transportation Branch Approval Record Model No. CE-250-2 Package Docket No. 71-9022 Revision No. 12 By application dated July 1,1988, as amended July 22 and 28 and August 4, 1988, Combustion Engineering, Inc. (CE) requested approval of U(5)0 powder 2
as new contents in the Model No. CE-250-2 package for Fissile Class II with Transport Index of 0.5.
Maximum U(5)09 powder per pail is restricted to 30 Kgs with a maximum H/V of 1.32 considering all sources of hydrogeneous material within the containment vessel. The maximum total contents per package are not to exceed 265 lbs, with the U-235 content not to exceed 5.3 kilograms.
The applicant established the suberiticality of the single damaged package and normal and accident arrays of the CE-250-2 packages with the subject contents using the KENO-IV Monte Carlo computer program with the 16-group Hansen-Roach crc 3s-section set. Approprit.te U-238/U-235 cross-section sets i
were determined by the s/ atom of the system under consideration. This calculational approach has succes'sfully calculated standard benchmarks and actual criticals.
The staff validated all the computer input-output atomic densities, geometric specifications and cross-sections supplied by CE for the normal and accident arrays, and the single damaged package. All computer runs were shown to be accurate and represented the cases intended.
The Keff calculated by CE are given in the following table:

The staff thus concludes that the Model No. CE-250-2 package satisfies requirements of 10 CFR Part 71 for the new requested contents of UO Powder 2
up to a maximum of 5 w/o in the U-235 isotope.
