Results of heterogeneous and homogeneous calculations for natural U rods in a loosely packed graphite lattice are compared, in order to determine the lattice size at which heterogeneous effects become important. HERESY-1 is a code used to calculate reactivities, power distributions, etc. Operating instructions, input-output descriptions, and the FORTRAN source program are presented for this code. HERESY-2 is a code similar to HERESY-1, with the exception that HERESY-2 includes multiple resonance effects. The sensitivity of the HERESY-2 calculations to several sorption occurs, the neutron energies at which resonance fission occurs, and the effects of resonance fission on reactivity.
