NEA-1543 ZZ-GEFF-2-GENDF.

1. NAME OR DESIGNATION OF PROGRAM:  ZZ-GEFF-2-GENDF.

3. DESCRIPTION OF PROGRAM OR FUNCTION

The package includes 2 group libraries.
GEFF-2
This P5 library for fusion neutronics calculations is based upon the 175 neutron, 42 photon VITAMIN-J group structure with the standard weighting function: Maxwellian (at the temperature to which the material is referenced) + 1/E + fission spectrum + 1/E + fusion peak + 1/E. It includes 93 materials from 1-H-1 to Bi-209 - almost all from EFF-2 basic data; but Ag-107, Ag-109, natural Cd, the 6 Hf isotopes and the 4 W isotopes were taken from JEF-2.2 - at 3
temperatures and 6 dilution cross section values; 10 thermal groups  are provided below 3 eV. Neutron cross sections and diffusion matrices, photon and gas production, kerma and DPA are given. The library includes H in H2O, metallic Be and Graphite for which an accurate treatment with S(alpha,beta) matrices has been provided for thermal scattering region, while all remaining materials have been treated with the 'free gas' approximation.
GEPDL
GEPDL is a 42 group photon interaction P8 library based upon EPDL-90 to be used in conjunction with GEFF-2 for preparing neutron + photon coupled libraries by means of codes like MATXSR - to produce data for TRANSX - or SMILER - an AMPX-77 module to produce AMPX Master Libraries from GENDF structured data.

4. METHOD OF SOLUTION

NJOY has been used to process both libraries; since the processing activities lasted over a couple of years, less  important materials were processed with the 91.13 version of the code and the 91.38 has been used to process all the remaining materials, including the whole GEPDL. Some very important modifications have been introduced in the code as far as the kerma computation is concerned, in order to solve problems due to physical inconsistencies of the data and non-standard formats of some materials, e.g. the lump reaction MT 10 - neutron diffusion in the continuum energy region - was not properly treated by the kerma module HEATR.
