Technical Review Report for the Justification for (sup 233)U Content Envelope Safety Analysis Report for Packaging Model 9975-85, Addendum 2

摘要

This report documents the review of Addendum 2, Justification for (sup 233)U Content Envelope, Safety Analysis Report for Packaging, prepared by Savannah River Packaging Technology (SRPT) of Savannah River National Laboratory (SRNL),--the Submittal--at the request of the Department of Energy's (DOE) National Nuclear Security Agency's (NNSA) Albuquerque Operations Office, for the shipment of 233U-bearing material from Los Alamos National Laboratory (LANL), in support of the Technical Area 18 (TA-18) Materials Relocation Program. This Addendum supplements the Safety Analysis Report for Packaging (SARP), Revision 0, and Addendum 1 to Revision 0 of the 9975 SARP (called Revision 0 of the 9975 SARP in this Addendum). The (sup 233)U-bearing items are currently stored at TA-18, awaiting shipment in the Model 9975-85 Package as a new Content Envelope, C.9. Following acceptance of this Addendum by the DOE-Headquarters Certifying Official (EM-60), and subsequent revision to the current Certificate of Compliance (CoC), the new contents will be authorized for shipment in the Model 9975-85 Package. The new Content Configuration, C.9, along with the optional Shielded-Pig Convenience Container Configuration, will be incorporated into the next revision of the Model 9975-85 Package SARP. In addition to the (sup 233)U-bearing items stored at TA-18, kilogram quantities of (sup 233)U-bearing materials are stored at Oak Ridge National Laboratory (ORNL). About one quarter of the items is Highly Enriched Uranium (HEU) as U(sub 3)O(sub 8) with (sup 233)U and (sup 232)U. Highly Enriched Uranium implies a (sup 236)U enrichment of >93%. The remaining material located at ORNL is pure (sup 233)U (>90%) with varying amounts of (sup 232)U. The form of the material is U(sub 3)O(sub 8), UO(sub 3), UO(sub 2), and U metal. Additional DOE Sites may also have (sup 233)U-bearing materials for shipment.
