3. DESCRIPTION OF PROGRAM OR FUNCTION


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

  FORMAT: MORSE

  NUMBER OF GROUPS: 125 groups

NUCLIDES: H, Li, C, Be, N, O, Na, Mg, Al, Si, K, Ca, Cr, Fe, Ni, Mn, Cu, Mo, Pb.

  ORIGIN: ENDF/B-IV, JENDL3-PR1

  WEIGHTING SPECTRUM:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Neutron transport calculation in arbitrary geometry. This is a revised version of MORSE-CG developed by ORNL. Multi-group double differential form cross sections are used as a library in addition to a Pl library.

4. METHOD OF SOLUTION

Monte Carlo method. The code can continuously sample a scattering angle mu.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Number of energy groups for DDL/B4 library: 125 groups. Geometry input: combinatorial geometry.
top ]
6. TYPICAL RUNNING TIME

Depends on problem and required precision. CPU is comparable with original MORSE-CG.
top ]
7. UNUSUAL FEATURES OF THE PROGRAM

The program is effective in solving accurately transport equations in mediums with highly anisotropic scattering cross sections such as a fusion reactor.
