This is the final report under award DE-FG07-02SF22608, project no. 2002-005, 'Engineering and Physics Optimization of Breed and Burn Fast Reactor Systems.' GFR cores having steady-state reload enrichments of 5 w/o U-235 were successfully developed and shown to satisfy neutronic, thermal hydraulic, materials and economic criteria. An innovative inverted (UC fuel outside coolant tube) vented fuel assembly design was developed to enable meeting project goals. The core was shown to be compatible with a conventional HTGR balance of plant (PCRV, helium primary coolant, Rankine power conversion system). B&B cores were found to be economically competitive on a once-through fuel cycle, without requiring reprocessing or recycle, and utilize natural uranium three to four times more efficiently than LWRs. However, fuel can be blended with natural uranium and reused in B&B GFRs or LWRs after only minimal processing.
