**RSICC CODE PACKAGE CCC-697**

**1. NAME AND TITLE**

GUI2QAD-3D: Point Kernel Code System for Neutron and Gamma-Ray Shielding Calculations in Complex Geometry, Including a Graphical User Interface.

**2. CONTRIBUTOR**

Safety Research Institute, Kalpakkam, Tamilnadu, India.

**3. CODING LANGUAGE AND COMPUTER**

Visual Basic 6 and Fortran 77; Pentium-III (C00697PC58601).

**4. NATURE OF PROBLEM SOLVED**

GUI2QAD is an aid in preparation of input for the included QAD-CGPIC program, which is based on CCC-493/QAD-CGGP and PICTURE. QAD-CGPIC is a Fortran code for fast neutron and gamma-ray shielding calculations through various shield configurations defined by combinatorial geometry specifications. Provision is available to interactively input the geometry and view the same in three dimensions with arbitrary rotations along x,y,z axis. The salient features of the present package include:

a) Handles off centered multiple identical sources

b) Axis of cylindrical sources can be parallel to any of the axes.

c) Provides plots of buildup factors (ANSI-1990) and material cross sections

d) Estimates dose rate for point source-slab shield situations

e) Interactive input of CG geometry with 3D view and rotation

f) Fission product decay power computation and plots for source term calculations.

g) Provision to read and graphical 1y display picture input file.

**5. METHOD OF SOLUTION**

The code QAD-CGPIC is based on point kernel method and has a provision to select either ANS-6.4.3 1990 GP buildup factor compilation or Capo's buildup factors.

**6. RESTRICTIONS OR LIMITATIONS**

Details on restrictions and limitations are available in the RSICC code manual CCC-493/QAD-CGGP. Because CCC-493 was obsoleted by CCC-645/QAD-CGGP-A, the CCC-493 documentation is not online on the RSICC website but is included with this package.

**7. TYPICAL RUNNING TIME**

Typical running time does not exceed 60 seconds.

**8. COMPUTER HARDWARE REQUIREMENTS**

A Pentium-III is required with 64 MB of Memory, 2GB disk drive, and a SVGA color monitor (1024x680).

**9. COMPUTER SOFTWARE REQUIREMENTS**

The graphical input section is coded in Visual Basic 6. The QADCGPIC executables was created with Lahey F77L/EM-32 V 5.2 compiler.
