Safety research needs for carbide- and nitride-fueled LMFBR's

Technical Report ·
OSTI ID:6476662
Economic incentives in terms of increased power density, breeding ratio and doubling times make the advanced fuels, mixed carbides and nitrides attractive. A limited amount of conceptual design and safety analysis have been reported for carbide-fueled LMFBR's and a modest amount of irradiation data exists for both fuels. This report summarizes the results of a study initiated at UCLA during the academic year 1974 to 1975. The report covers the following tasks: review core and primary system designs for any significant differences from oxide fueled reactors; review carbide (and nitride) fuel element irradiation behavior; review reactor behavior in postulated accidents; examine analytical methods of accident analysis to identify major gaps in models and data; and examine post accident heat removal.
