PSR-0065 APSAI.

1. NAME OR DESIGNATION OF PROGRAM:  APSAI. Activity calculations and plotting of neutron or gamma-ray spectra from ANISN calculations using INTRIGUE-II-C package.

3. NATURE OF PHYSICAL PROBLEM SOLVED

APSAI enables the user to plot fluxes obtained from one or more previous ANISN calculations. It is possible to plot on the same graph output from up to 9 different ANISN runs having the same energy groups, mesh spacing, and geometrical size. Further, the user can plot several geometry- or energy-dependent fluxes on the same figure, often an advantage.
Subroutine ACTIV allows plotting the absorption densities dependent on the x coordinate. In addition, the damage flux and up to 5 activities at the outer boundary can be calculated.
Plotting is executed using the INTRIGUE-II-C package which allows both CRT and pen-and-ink plotting.

4. METHOD OF SOLUTION

In order to minimize the core requirements, the  fluxes for each ANISN case are read after the previous case is executed. If the fluxes are read from cards, flux cards must be repeated in the input if both energy- and geometry-dependent plots are desired. In order to avoid that, it is advisable to plot the geometry and energy dependent cases in different runs when the fluxes are read from input cards.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

On account of fixed dimensioning, the number of energy groups must be <= 100 and the number of mesh intervals <= 150.
   The graph paper size is 10 in. X 14 in.
   Maximum number of different ANISN cases is 9.
   Maximum number of curves on each graph is 16.
Maximum number of calculated activities of the outer boundary    is 5.

6. TYPICAL RUNNING TIME

For 100 energy groups, 150 mesh points, 6 geometry, 6 energy dependent curves, and 5 activities from 2 ANISN cases on IBM 360/91, the CPU time was 18 seconds.

8. RELATED AND AUXILIARY PROGRAMS

Plotting is carried out using the INTRIGUE-II-C package. CRT and pen-and-ink plotting versions are both possible.
A similar code (CCPLT) can plot neutron and gamma-ray fluxes from ANISN and DOT calculations. The main reason for developing APSAI is  that CCPLT can plot only one curve on the same figure and can be used for only one ANISN or DOT case.
