3. NATURE OF PHYSICAL PROBLEM SOLVED

  FORMAT: GAM-II

  NUMBER OF GROUPS: 32-energy-group split (0.4 to 1234 eV).

  NUCLIDES: tungsten (W,) and depleted uranium (U,) slabs

  ORIGIN:

  WEIGHTING SPECTRUM:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Multigroup capture and scatter cross sections in the resolved resonance region were calculated for tungsten and depleted uranium slabs for use in shielding calculations of neutron transport and capture distributions.  Slabs of thickness of 1 to 8
centimeters surrounded by hydrogen or lithium hydride were considered.  GAROL  was  used to  generate  the  cross sections, a
method previously observed to preserve the total capture rate  in a detailed multigroup neutron transport calculation for a thick resonance absorber. Average cross sections were calculated for a
32-energy-group split (0.4 to 1234 eV) compatible with that used by GAM-2. Group fluxes are also presented permitting further group collapsing either by hand calculations or with an included computer  program.
