PSR-0306 KAOS-V

1. NAME OR DESIGNATION OF PROGRAM:  KAOS-V (An Evaluation Tool For
Neutron Kerma Factors And Other Nuclear Responses).

3. DESCRIPTION OF PROGRAM OR FUNCTION

KAOS-V evaluates accurately the neutron fluence-to-Kerma factors from microscopic nuclear data.

4. METHOD OF SOLUTION

Two basic methods for computing kerma factors,  namely kinematics and energy balance, are implemented in KAOS-V. KAOS-V uses data from the evaluated nuclear data files ENDF/B-V. Auxiliary nuclear data bases, such as the Japanese evaluated nuclear data library JENDL-2 can be used as a source of isotopic cross sections. These are needed to estimate average quantities such as effective Q-values for the natural element. For resonance treatment, the code has the ability to access NJOY and NPTXS interface files in formatted or binary forms.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM:  None noted.

6. TYPICAL RUNNING TIME:  The sample problem took about 1.5 minutes on  the Cray.

NEA Data Bank implemented the program on the following computers: (1) PC with Intel Pentium 200MHz processor; (2) IBM RISC/6000 Workstation; (3) DEC ALPHA Workstation. The execution times of the test case included in the package were (in seconds) 14.45 for (1); 38.51 for (2); 73.89 for (3).

7. UNUSUAL FEATURES OF THE PROGRAM:

Graphics output is in EPS format.

11. MACHINE REQUIREMENTS:  The code runs on the Cray computers.

NEA Data Bank implemented the program on the following computers: (1) PC with Intel Pentium 200MHz processor; (2) IBM RISC/6000 Workstation; (3) DEC ALPHA Workstation.

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED

The code was written in FORTRAN 77 under the CTSS operating system. The CFT compiler is used. The plotting routines require the DISSPLA graphics system.

NEA Data Bank implemented the program on the following computers: (1) PC with Intel Pentium 200MHz processor running under MS-DOS (Windows95) with the Lahey compilers f77 5.2 and f90 3.40a; (2) IBM RISC/6000 Workstation running AIX 3.2 and  the compiler xlf; (3) DEC ALPHA Workstation running OSF/1 and the compiler f77.

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS:

The VIEWR module of NJOY-94 has been included to replace DISSPLA.
