Several Fu-fueled power breeders have been analyzed by the multi-group method. The results indicate that a feasible reactor can be made having fissile and fertile material in the form of an oxide in both core and blarket. One possible reactor with 6 atoms U/sup 238/ per Pu in the core and 43 volume% Na has a critical mass of about 450 kg, a breeding ratio of about l.4 of which 0.66 is internal, and a power of about 800 Mw. Replacing the metal U blanket with U oxide results in no significant reduction in breeding ratio but makes possible more economical reprocessing of blanket material. Farther calculations are planned.
