the u s heu disposition program
The U.S. HEU Disposition Program
  • NNSA’s 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

HEU Disposition Paths
usec heu transfer
USEC HEU Transfer
  • The USEC HEU Transfer project, mandated by the USEC Privatization Act, was completed during 2006.
  • 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.
tva off spec bleu program

Browns Ferry Nuclear Power Plant

Lead assembly being inspected at TVA’s Sequoyah Plant

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 June2009, 38 MTU has been down-blended
tva off spec program cont

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 Energy’s Project Management Award – SRS Line Item
    • 2005 Platt’s 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
h canyon eu disposition project

Super Kukla Ring size reduction

H Canyon EU Disposition Project
  • NNSA has identified 20.8 MT of HEU that could result in up to 250 MT of additionaloff-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.
reliable fuel supply initiative rfs
Reliable Fuel Supply Initiative (RFS)
  • Secretary Bodman announced the RFS initiative for foreign users who do not pursue enrichment and reprocessing at IAEA’s 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.

rfs general status
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.
12 1 mtu heu downblending project
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.
foreign research reactor leu fuel
Foreign Research Reactor LEU Fuel

DOE/NNSA Supplies 80% of the world’s 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).
  • 2.9MT down-blended to date
  • Customers in Europe, Canada, Asia, South America, Australia

RA-6 Reactor, Bariloche, Argentina

CEA OSIRIS Reactor, France

what does the future hold
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
final thoughts
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.
