3. DESCRIPTION OF PROGRAM OR FUNCTION

QAD-CG is a point-kernel code for calculating the fast-neutron and gamma-ray penetration through various shield configurations defined by combinatorial geometry specifications.
top ]
4. METHOD OF SOLUTION

QAD-CG uses a point kernel ray-tracing technique for gamma-ray calculations and either a modified Albert-Welton kernel or kernels obtained from the moments method solution of the Boltzmann equation for neutron penetration calculation. The GP version optionally makes use of the Geometric Progression (GP) fitting function for the gamma-ray buildup factor.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM:  An 8087 co-processor is required for the IBM PC version.

6. TYPICAL RUNNING TIME

The sample problems each took about 1 minute  on the IBM 3033, including compiling and linking. Execution required more than an hour on the IBM PC.
CCC-0493/01
NEA-DB executed the test cases included in this package on an IBM 3084 computer. CPU times required were: 11 seconds (shipping cask problem); 58 seconds (QAD test run); 0.6 seconds (PICTURE).

8. RELATED AND AUXILIARY PROGRAMS

The present version is based on CCC-307/QAD-CG contributed by Bechtel Power Corporation, Gaithersburg, Maryland and modified by JAERI. In August 1986, double precision combinatorial geometry routines from CCC-203/MORSE-CG replaced the older geometry routines provided in the original QAD-CGGP from Japan.

The code was modified in October 1988 to accommodate the ANS-6.4.3 1988 buildup factor compilation (26 materials).
