4. HISTORICAL BACKGROUND AND INFORMATION The Evaluated File (EFF-1), together with the Joint European File (JEF-1), is rapidly becoming the standard European data source for thermal reactors, fast reactors, fusion, shielding and controlled thermonuclear analysis. JEF is administered by the Nuclear Energy Agency (NEA Data Bank). While processing the EFF-1 data in order to obtain a 175 neutron - 38 gamma group library GEFF-1, gas production cross sections, neutron and photon kerma factors were also computed.
5. APPLICATION OF THE DATA
The cross section data and kerma factors are written in the FOURACES (PSR-183) format and can be used by transport and discrete ordinates codes which can read this format.
6. SOURCE AND SCOPE OF DATA
For the gas production cross sections, the lump reactions 203 to 207 included in EFF-1 were assumed as the basis of the computation. The neutronic kerma factors were calculated through the THEMIS module KERMA. The photonic kerma factors were computed from the DLC-99/HUGO of gamma interaction data through the THEMIS module GROUPG. Some neutronic kerma factors appeared to be doubtful because of threshold values not exactly stated in EFF-1; these data have been discarded.
