ABSTRACT

Design and safety analyses to determine an optimum LEU fuel assembly design using U₃Si₂-Al fuel with up to 4.8 g/cm³ for conversion of the HFR Petten reactor were performed by the RERTR program in cooperation with the Joint Research Centre and NRG. Credibility of the calculational methods and models were established by comparing calculations with recent measurements by NRG for a core configuration set up for this purpose. This model and methodology were then used to study various LEU fissile loading and burnable poison options that would satisfy specific design criteria.
