Annular Fuel Test Rig
Irradiated in 2004

  • Internally and externally cooled annular fuel evaluated for ability to increase power density with better safety margins than current fuel.
  • Evaluated ability to achieve high reactivity-limited burn-up in order to prove reasonably long refueling cycle.
  • Two fuel samples irradiated for three months.
  • Post-Irradiation Examination scheduled for Summer 2005.
