ABSTRACT
A neutronic feasibility study for converting the Brookhaven Medical Research Reactor
from HEU to LEU fuel was performed at Argonne National Laboratory in cooperation with
Brookhaven National Laboratory. Two possible LEU cores were identified that would provide
nearly the same neutron flux and spectrum as the present HEU core at irradiation
facilities that are used for Boron Neutron Capture Therapy and for animal research. One
core has 17 and the other has 18 LEU MTR-type fuel assemblies with uranium densities of
2.5g U/cm3 or less in the fuel meat. This LEU fuel is fully-qualified for
routine use. Thermal hydraulics and safety analyses need to be performed to complete the
feasibility study.
