1. NAME AND TITLE

ANIPLO-D50: A Digital Computer Program for Plotting Results from Calculations with the S_n Computer Program ANISN.

2. CONTRIBUTOR

Gesellschaft f. Kernenergieverwertung in Schiffbau und Schiffahrt mbH, West Germany through the NEA Data Bank, Gif-sur-Yvette, France.

3. CODING LANGUAGE AND COMPUTER

Fortran IV; IBM 3033.

4. NATURE OF PROBLEM SOLVED

ANIPLO-D50 plots results determined by the use of the discrete ordinates neutron and gamma ray transport code ANISN. In particular, the space-dependent scalar fluxes and responses such as the dose rate may be plotted.

5. METHOD OF SOLUTION

The input is divided into two parts: 1) the "library: data defining the energy group structure, the spatial mesh, and giving the scalar flux in the configuration," and 2) the "problem" data which is repeated for each plot required, giving the title of the plot and the x and y axes, and the flux to dose conversion factor if dose rates are plotted. Fluxes and doses (for each energy group and summed over all groups) are plotted against the space variable. The scalar fluxes are read in from cards, output from ANISN when ID1 = 2.

Flexibility is available in the size of the plot, log. or lin. axes, etc.

6. RESTRICTIONS OR LIMITATIONS

The maximum number of energy groups is 25. The maximum number of spatial intervals is 400.

7. TYPICAL RUNNING TIME

A sample problem with 9 energy groups and 73 intervals takes 0.46 minutes on an IBM 3033 computer.

8. COMPUTER HARDWARE REQUIREMENTS

ANIPLO-D50 is operable on the IBM 3033 computer.

9. COMPUTER SOFTWARE REQUIREMENTS

A Fortran IV compiler is required.
