  1. AFCI Reactor-Accelerator Coupling Experiments (RACE) Project Prof. Denis Beller Project Director Idaho State University (e-mail: beller@egr.unlv.edu) Eighth Information Exchange Meeting on Actinide and Fission Product Partitioning and Transmutation Nov. 11, 2004

  2. RACE Project • Design, model, and conduct ADSS experiments • Predict and analyze subcritical multiplication and source-driven transients • Map source importance & flux in and around a variety of ADSS • Provide a bridge between MUSE and TRADE

  3. Idaho State University leads a growing RACE consortium • IAC RACE ADSS • UT-Austin & Texas A&M TRIGAs • UNLV TRP • U of Michigan • ANL-West • LANL

  4. Driving neutron sources: • MUSE DT-neutron source • ~1.5x1010 n/s, 2.45 & 14.1 MeV • TRADE p+ source will make about • 1015 n/s, up to 140 MeV • Quite a jump! • RACE linear electron accelerator: • Up to ~1013 n/s • Intermediate energy: spallation-like spectrum plus small tail up to 30+ MeV

  5. ADSS Experiments Comparison

  6. RACE ADSS Characteristics

  7. Tentative Experiment Schedule • ISU-IAC • Design & licensing Aug ’03-Mar ’04 • Construction Feb-Apr ’04 • Experiments Apr ’04-Jun ’05 • UT-Austin Experiments Spring ’05-? • TRIGA, other • Texas A&M Experiments Fall ’05-’07+ • TRIGA, used fuel core, LBE Fall ‘07

  8. RACE Progress • Design studies completed at Texas A&M and UT • Fresh fuel and fresh reactor at UT • Texas A&M may build permanent ADSS • Static and transient analyses completed at U of Mich • New UNLV TRP project approved • Seven ADSS experiments at ISU-IAC

  9. 75% W, 25%Cu target for ISU RACE, 2 ¾” diameter x 3” long

  10. Target with thermocouples

  11. Comparison of MCNPX flux and Mn Activation Measurements

  12. In June we installed a new system • Replaced accelerator • Large Al vessel • Graphite reflector • Water moderator

  13. Accelerator and “large” vessel

  14. RACE fuel trays and target inside the graphite reflector

  15. Preliminary results:Gold activation versus MCNPX

  16. Time-dependent measurement

  17. Conclusion • ADSS Exp at ISU, UT, and Tx A&M • Now thru 2006 or beyond • Design, modeling, and execution • Predict and measure subcritical multiplication, source-driven transients, and map source importance • Recruit, educate and train students • Transmutation
