ABSTRACT
The Monte-Carlo transport code MCNP was used to
evaluate possible arrangements of cores for the MIT
Reactor using monolithic LEU fuel. Plate and moderator
thicknesses were varied, and fixed absorbers and inner
reflectors added in an effort to maximize available
neutron fluxes at in-core and ex-core locations of
experimental facilities. Addition of D2O in the H2O
moderator was also evaluated. Comparisons of the fast,
epithermal, and thermal fluxes were made at selected
locations. Keff was also evaluated and critical blade
heights compared with the existing HEU core. Results
indicate that the LEU fluxes could approach HEU values
with the use of a fueled in-core experimental facility,
a fixed boron absorber spider and an inner beryllium
reflector.
