3. DESCRIPTION OF PROGRAM OR FUNCTION

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
FORMAT: to be used in point kernel codes such as QAD-CGGP.

 

NUMBER OF GROUPS: -- (energy range 15 keV to 15 MeV)

 

NUCLIDES: Be, B, C, N, O, Na, Mg, Al, Si, P, S, Ar, K, Ca, Fe, Cu, Mo, Sn, La, Gd, W, Pb, U and 3 mixtures (water, air and concrete).

 

ORIGIN: American Nuclear Society Standards Working Group ANS-6.4.3

 

WEIGHTING SPECTRUM: --

 

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

The GP coefficients as used in the Daniel code will reproduce the build-up factor data of ANS-6.4.3 typically within a few percent. The energy range is 15 keV to 15 MeV. Air and medium response data are provided for 23 elements and 3 mixtures (water, air and concrete). The basic compilation extends to 40 mean free paths, but the GP method is capable of interpolation in energy and extrapolation in thickness.

 

Two significant changes were made in the 1990 update: the G-P coefficients were revised from new PALLAS build-up factor calculations of the elements molybdenum and above in the table giving data for all elements, and a table of Taylor coefficients was added. In addition, G-P coefficient files were added for the high-Z elements which give detail near the absorption edges. Factors to correct for neglect of coherent scattering and for the change in spectra at the shield-tissue interface are included.

 

Build-up factor tables were added in 1991, and some corrections were made to the Taylor coefficient files.

6. TYPICAL RUNNING TIME

The sample case executes in less than a second on the IBM 3033.

8. RELATED OR AUXILIARY PROGRAMS

ANS643 is based on the 1988 build-up factor compilation of American Nuclear Society Standards Working Group ANS-6.4.3. The compilation is based on published and unpublished data from moments method and other sources. The build-up factor coefficients were determined in Japan from the compilation of ANS-6.4.3 and used in CCC-493/QAD-CGGP.

 

A FORTRAN 77 code called Daniel will provide build-up factors from the coefficients. It consists of QAD-CGGP subroutines which process GP data and a main routine which together provide an example for incorporation of the GP technique into other applications.
