Once the UMo monolithic LEU fuel is qualified, MITR has a number of future plans to prepare for conversion that draw on the technical work described in the previous sections. First, a preliminary safety analysis report will be prepared and approved prior to conversion. Second, because the fuel fabrication requirements are unique to the MITR reactor, fuel manufactur­ing tolerances will need to be determined. Finally, all cores up to the last full HEU core will need to be analyzed using the newly upgraded neutronics model; this model will also be used for fuel management.

MITR staff is using the requirement to convert to LEU fuel to improve its analysis capabilities and obtain a greatly improved understanding of the reactor. These improved capabilities have resulted in an optimized LEU fuel design for the MITR reactor.
