3. DESCRIPTION OF PROGRAM OR FUNCTION

QAD-CGGP-A is a point-kernel code for calculating fast-neutron and gamma-ray penetration through  various shield configurations defined by combinatorial geometry specifications. AECL developed this release by modifying the CCC-0493/QAD-CGGP package. The major improvements to the new version include the incorporation of a cubic spline interpolation scheme for the gamma attenuation coefficients, an added capability for source translation and rotation, correction of a potential error in evaluation of buildup factors at very deep penetration, and the adoption of complete free-format input reading routines from KENO-IV.
CCC-0493/QAD-CGGP was based on CCC-0307/QAD-CG contributed by Bechtel Power Corporation, Gaithersburg, Maryland and modified by Japan Atomic Energy Research Institute, Tokai-mura, and Oak Ridge National Laboratory. The GP parameters were determined by the Tokyo Institute of Technology, Tokyo, Japan and JAERI. In August 1986, double precision combinatorial geometry routines from CCC-0203/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).
The G-P buildup factor coefficients for the elements molybdenum to uranium were updated in July 1990 from new PALLAS calculations based on DLC-0136/PHOTX. The DLC-0129/ANS643 package was also updated with data from the PALLAS calculations.

4. METHOD OF SOLUTION

QAD-CGGP-A 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 calculations. 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:  A math coprocessor is required for the PC version.

6. TYPICAL RUNNING TIME

Using the sample UNIX script, QAD-CGGP-A ran  all the sample problems in a total of 5 minutes 14 seconds on an IBM RS/6000-590 running AIX 3.2.5.
CCC-0645/01
At the tests performed by the NEA/DB, the program QAD-CGGP-A was installed and the sample problems were executed on:

- DEC 3000 Model 300X, equipped with a Alpha/AXP architecture

  processor, running Digital UNIX V3.2G (Rev. 64)

- PC DELL Optiplex GXM 5100 equipped with a Pentium processor at 99
  MHz, base memory 640 Kbyte and extended memory 32 MByte, running

  MS-DOS 6.2

The following Table displays the execution (elapsed) times in both machines for each of the 19 sample problems.
