This Technical Review Report (TRR) summarizes the results of the Staff’s review of the Model 9977-96 Package, Addendum 3, Revision 4 for the Type 4 contents. Type 4 contents may include ²³⁸Pu, ²³⁹Pu, ²⁴¹Am, ²⁴⁴Cm, ²⁵²Cf, ⁹⁰Sr, ²²⁶Ra, ¹³⁷Cs, ⁶⁰Co, ¹⁹²Ir with the Special Actinide Isotopes (²⁴²mAm, ²⁴³Cm, ²⁴⁵Cm, ²⁴⁷Cm, ²⁴⁹Cf and ²⁵¹Cf) limited to a total of 1000 ppm. Type 4 pertains primarily to the Off-Site Source Recovery Project (OSRP). These new contents will be authorized for shipment in the Model 9977-96 Package, supplementing existing Revision 2 to the Safety Analysis Report for Packaging (SARP), once Addendum 3, Justification for Small Gram Quantity (SGQ) Contents, is accepted by the certifying official, EM-40, and the existing Certificate of Compliance (CoC) is revised, reflecting the added contents. Existing Content Envelopes for the Model 9977-96 Package include heat sources in food-pack cans or in radioisotope thermoelectric generators (RTGs), neptunium metal, a beryllium-reflected plutonium ball, plutonium/uranium metal at 25% and 50% maximum 240Pu, respectively, and uranium metal at limits of 95% and 100% 235U, respectively. The percentages are of total radioactive material mass. The Isentropic Compression Experiment (ICE) apparatus is an additional content of the Model 9977-96 Package SARP. The latest content added to the Model 9977-96 Package is Type 5, AGR fuel compacts. Addendum 3 was prepared by Savannah River Packaging Technology, Savannah River National Laboratory, Savannah River Nuclear Solutions, LLC, Savannah River Site, in support of work being performed by LANL. The Model 9977-96 Package is currently certified under two Certificate of Compliance Numbers, i.e., USA/9977/B(M)F-96 (DOE) and USA/9977/B(M)F-96 (DOE-S/T-1), covering transportation and periodic and extended maintenance, respectively. For transportation, the Safety Analysis Report for Packaging is S-SARP-G-0001, Revision 2 (August 2007). Extended maintenance is covered by Addendum 1, Justification for DNDO Contents, S-SARA-G-00003, Revision 2 (October 2008). The new Content Envelope and container configurations will be incorporated into the next revision to the Model 9977-96 Package SARP. This TRR addresses only Type 4 contents; content Types 1, 2, and 3 will be covered under a separate TRR. Content Type 5 has been dealt with in a previous TRR. Hereafter, in this TRR, the Type 4 content may be referred to as Sources.
