RSICC CODE PACKAGE PSR-549

1. NAME AND TITLE

CAFDATS: Converter of Angular Fluxes of DORT, ANISN and TORT Systems.

2. CONTRIBUTORS

Developed by Mitsui Engineering and Shipbuilding Co., Ltd., Tokyo, Japan and contributed by the Institute of Nuclear Safety, NUPEC, Tokyo, Japan through the NEA Data Bank, Issy-les-Moulineaux, France.

3. CODING LANGUAGE AND COMPUTER

Fortran; SUN or Linux PC (P00549MNYCP00).

4. NATURE OF PROBLEM SOLVED

CAFDATS is a converter of angular fluxes of the DORT, ANISN and TORT systems. It works similarly to the TORSED or TORSET program in the DOORS code systems, and is designed to calculate the boundary source for the ANISN and DORT codes from the calculated fluxes by the DORT or TORT code.

5. METHOD OF SOLUTION

CAFDATS is designed to calculate the boundary source for the ANISN and DORT codes from the calculated fluxes by DORT or TORT. There are five sub-programs in the program package:

         TXTODR converts calculated fluxes in the Cartesian geometry (X, Y, Z) of TORT code to the boundary source in the cylindrical geometry (R, Z) of DORT code,

         TRTODR converts calculated fluxes in the cylindrical geometry (R, Theta, Z) of TORT code to the boundary source in the cylindrical geometry (R, Z) of DORT code,

         TRTOAR converts calculated fluxes in the cylindrical geometry (R, Theta, Z) of TORT code to the boundary source in the infinite cylindrical geometry (R) of ANISN code,

         TXTOAX converts calculated fluxes in the Cartesian geometry (X, Y, Z) by TORT code to the boundary source in the infinite plane geometry (X) of ANISN code,

         DRTODR converts calculated fluxes in the cylindrical geometry (R, Z) by DORT code to the boundary source in the cylindrical geometry (R, Z) of DORT code.

The angular fluxes for the boundary source of the secondary calculation are linearly interpolated from the nearest-neighbor angular fluxes in the angular and spatial meshes of the primary calculation.

6. RESTRICTIONS OR LIMITATIONS

There are some limitations on the dimensions of certain arrays, but these dimensions can be increased to meet user's requirements.

7. TYPICAL RUNNING TIME

The estimated running time of the sample problem is 10 minutes on a SUN Work Station U60.

8. COMPUTER HARDWARE REQUIREMENTS

CAFDATS runs on computers running UNIX or Linux.

9. COMPUTER SOFTWARE REQUIREMENTS

This package was compiled at RSICC on an AMD Opteron running Red Hat Enterprise Linux WS release 4 with PGF95 -V 6.1-6. Fortran source code is included and a compiler is required.
