U.S. HEU Disposition Program Robert M. George Office of Fissile Materials Disposition International Nuclear Materials Management Annual Meeting July 2009 Slide 2 2 The U.S. HEU Disposition Program NNSAs U.S. HEU Disposition Program is a key nonproliferation program that down-blends surplus HEU and uses the derived LEU in commercial and research reactors. Commercial down-blend contractors include: Babcock and Wilcox Nuclear Fuel Services Nuclear fuel fabricators have also been involved in down-blending projects AREVA and WesDyne Slide 3 3 HEU Disposition Paths Portsmouth Gaseous Diffusion Plant Uncommitted 2005 Material ~40 MT * ~10 MT UF 6 USEC Transfer Material 47 MT 14 MT TVA Off-Spec (BLEU) Material 51 MT Savannah River Site and Nuclear Fuel Services, Inc.

The down-blending was completed at Babcock & Wilcox in Lynchburg, VA in June 2006. A total of 46.6 MT HEU, at an average assay of 43.7%, was delivered and down-blended to make over 800 MT of commercial-grade LEU. Slide 5 5 TVA Off-Spec BLEU Program DOE and TVA entered an Interagency Agreement in 2001 -With addition of EU Disposition Project material, it now covers ~45.6 MTU -TVA is using blended low-enriched uranium (BLEU) fuel in the Browns Ferry and Sequoyah Nuclear Plants. -Down-blending occurs at two facilities: -Savannah River Site, Aiken, SC solutions, alloyed metals, oxides (~22.6 MTU) -Nuclear Fuel Services, Erwin, TN uranium metal, alloyed metals, compounds (~ 23 MTU) -As of the end of June 2009, 38 MTU has been down-blended Browns Ferry Nuclear Power Plant Lead assembly being inspected at TVAs Sequoyah Plant Slide 6 6 TVA Off-Spec Program (Cont.) BLEU project HEU shipments were completed in 2008 40 MT Down-blending will be completed in fall of 2009 (~95% complete) Additional down-blending of EU Disposition Project material will occur in 2009 & 2010 Savings to the U.S. Treasury are expected to be over $255 million. This program has won many awards 2003 Secretary of Energys Project Management Award SRS Line Item 2005 Platts Global Energy Engineering Project of the Year BLEU/Off-Spec Partnership 2006 NEI Top Industry Practice (TIP) award BLEU Project Several Other Internal TVA Awards Broken Button Slide 7 7 H Canyon EU Disposition Project NNSA has identified 20.8 MT of HEU that could result in up to 250 MT of additional off-spec LEU over the 2009 through 2020 time period. The HEU would be recovered and down-blended at SRS H Canyon Complex. NNSA and TVA have agreed to mutually beneficial terms to add an initial 5.6 MT of the material to the existing Interagency Agreement. Incremental additions of the remaining material into the TVA Off-Spec Fuel Project may occur as funding becomes available. Super Kukla Ring size reduction Slide 8 8 Reliable Fuel Supply Initiative (RFS) Secretary Bodman announced the RFS initiative for foreign users who do not pursue enrichment and reprocessing at IAEAs General Conference in September 2005. 17.4 MT of HEU will be down-blended to produce about 290 MT LEU, a substantial majority of which will be used as a stockpile for the RFS program. The RFS program will ensure that, in the event nuclear fuel is not available commercially, there will be reliable access to the market. MTR Type Fuel Element Cast Metal Slugs Slide 9 9 RFS General Status In June 2007, NNSA awarded a downblending and storage contract to the WesDyne / NFS team. Through June 2009, NNSA has shipped over 15 MT of HEU for the RFS project. Processing of the HEU began in March 2008 and through June 2009, over 5.6 MT has been down-blended to date. The down-blending program will be completed in 2010. Slide 10 10 12.1 MTU HEU Downblending Project HEU will be down-blended during the 2009 2012 time period. Project will provide total derived LEU of about 220 MTU Inventory reserved for use by MOX project if needed. Down-blending and storage contract awarded June 23 to WesDyne/NFS team. Slide 11 11 Foreign Research Reactor LEU Fuel DOE/NNSA Supplies 80% of the worlds LEU research reactor fuel with down-blended HEU Material is provided in support of the Reduced Enrichment for Research and Test Reactors (RERTR) program, which reduces civil uses of HEU worldwide. U.S. surplus HEU (10 MT) is feed material to make LEU fuel (mostly 19.75% enrichment). 2.9 MT down-blended to date Customers in Europe, Canada, Asia, South America, Australia RA-6 Reactor, Bariloche, Argentina CEA OSIRIS Reactor, France Slide 12 12 What Does the Future Hold? The program has already committed to down- blending projects 161MT of the total 217 MT of surplus, commercially-usable HEU. The remaining 56 MT is expected to become available for down-blending from now through 2050. Future focus is: Continue progress in down-blending HEU to meet nonproliferation objectives Proper disposition of derived LEU in a manner that does not adversely impact the commercial nuclear fuel markets Develop future projects from unallocated HEU inventories using a viable funding approach Slide 13 13 HEU Deliveries for Down-blending (Actual and Projected as of March 2009) Slide 14 14 Final thoughts Through June 2009, this program has eliminated the proliferation risk of approximately 124 MTU of HEU, which equates to approximately 2,773 nuclear warheads. Several DOE facilities have been able to eliminate or greatly reduce their holdings of HEU. The LEU derived from down-blending the U.S. HEU equates to ~1,400 MTU.
