RSIC COMPUTER CODE PSR-064
1. NAME AND TITLE
DOMINO: A General Purpose Code System for Coupling Discrete Ordinates and Monte Carlo
Radiation Transport Calculations.
Oak Ridge National Laboratory, Oak Ridge, Tennessee.
NUS Corporation, Rockville, Maryland.
The University of Wisconsin, Madison, Wisconsin.
3. CODING LANGUAGE AND COMPUTER
Fortran IV; IBM 360/370 (A), CDC 6400 (B), UNIVAC-1110 (C).
4. NATURE OF PROBLEM SOLVED
DOMINO is a general purpose code for coupling discrete ordinates (Sn) and Monte Carlo radiation
transport calculations. In particular, DOT calculations in r-z geometry may be coupled with MORSE
calculations of arbitrary geometric complexity. DOMINO is essentially a data processor for the
angular flux tape produced by the discrete ordinates calculation.
5. METHOD OF SOLUTION
DOMINO transforms the angular flux as a function of energy group, mesh interval, and discrete
angle into current and subsequently into normalized probability distributions.
6. RESTRICTIONS OR LIMITATIONS
The discrete ordinates calculation is limited to an r-z geometry.
DOMINO requires as input the spatial mesh, angular quadrature and number of groups used in the
discrete ordinates calculation. The surface (either top, bottom, or side) or the boundary number of the
internal disk or cylindrical surface and the direction (in, out, up, or down) must be specified.
7. TYPICAL RUNNING TIME
On the IBM 370/165 computer, a problem consisting of 12 groups, 5 radii, and 40 angles ran in
about one second.
8. COMPUTER HARDWARE REQUIREMENTS
DOMINO is operable on the IBM 360/370, CDC 6400, or UNIVAC-1110 computers.
9. COMPUTER SOFTWARE REQUIREMENTS
A Fortran IV compiler is required.
