[en] The University of Missouri Research Reactor (MURR) is working on licensing a new fuel design. There are two goals for this new fuel design: (1) reduce the fuel cycle cost of the current 10-MW operation; and, (2) provide a core capable of operating at a significantly higher power level for our upgrade. For the first goal, a fuel element with a higher ²³⁵U loading, a higher fissions per cubic metre burnup limit, and a uniform power density are desired. The uniform power density, i.e., low peaking factors, is also very important in obtaining the second goal. The various options considered to achieve these goals (core and element shape, fuel plate design, fuel type, and burnable poisons and varying the amounts of fuel loaded per plate) are described along with the results obtained for the new core design
