    The primary focus points of a report entitled "Technical Basis Report on Low Enriched Uranium Silicide-Aluminum Dispersion Fuel for High Power Research Reactors" are described in this paper. In the US Reactor Conversion program, U3Si2-Al dispersion fuel was developed. In 1988, the US NRC's safety evaluation report (NUREG-1313) concluded that U3Si2-Al plate-type fuel was acceptable for use in research and test reactors with uranium densities up to 4.8 gU/cm3 in the meat at the power level investigated in the demonstration tests. Fuel performance at the power conditions included in NUREG-1313 are summarized. As interest has recently been revived for higher power applications of this fuel, the effect of highpower conditions on fuel performance is addressed. In addition, the effect of Udensities higher than 4.8 gU/cm3 is discussed. Knowledge gap items associated with higher power and higher U-density applications are identified together with the proposed resolution methods.
