3. DESCRIPTION

MATJEFF31.BOLIB /1/ is a multi-group coupled (199 neutron groups + 42 photon groups) pseudo-problem-independent cross section library in MATXS format for nuclear fission applications. MATJEFF31.BOLIB is based on the JEFF-3.1 /2/ OECD/NEA Data Bank evaluated nuclear data library and it was processed, through the NJOY-99 /3/ system, in the VITAMIN-B6 /4/ library group structure using the same calculation methodology.

Since the data processing of MATJEFF31.BOLIB was performed before the release of the JEFF-3.1.1 /5/ evaluated nuclear data library, at the end of February 2009, an additional separated set of JEFF-3.1.1 processed data files was recently included for the following 12 nuclides, obtained for consistency with the same NJOY version previously used: O-16, Cl-35, Ca-46, Cr-52, Fe-56, Zr-91, Zr-96, Mo-95, Eu-154, U-233, Np-237 and Pu-239. Concerning this additional set of JEFF-3.1.1 data files, it was decided to reprocess only the nuclides already inserted in the list of processed files for MATJEFF31.BOLIB whose evaluations were updated or corrected in the JEFF-3.1.1 library. MATJEFF31.BOLIB was extensively tested on many thermal, intermediate and fast neutron spectrum criticality safety benchmark experiments.

4. METHODS

The ENEA-Bologna Nuclear Data Group produced the MATJEFF31.BOLIB library in co-operation with a specialist, formerly at the Obninsk Institute of Physics and Power Engineering (IPPE-Obninsk, Russian Federation). The MATJEFF31.BOLIB library for nuclear fission applications was conceived as a European counterpart of the VITAMIN-B6 American library, based on the ENDF/B-VI Release 3 evaluated data library. The present library has in particular the same group structure and general features as VITAMIN-B6 and was produced using the same data processing methodologies, based on the NJOY data processing system.

The NJOY-99.160 data processing system was used for the MATJEFF31.BOLIB library generation to assure the consistency with the previous generation of the VITJEFF31.BOLIB /6/ twin library, based on the same GENDF cross section data file. In particular it was used a revised version of the GROUPR /7/ module, originally developed in ENEA-Bologna before the free release of an analogous GROUPR revised version with NJOY-99.161, in order to correctly deal with the non Cartesian interpolation schemes, contained in 69 JEFF-3.1 evaluated nuclear data files.

The TRANSX-2.15 /8/ code was then used to obtain the total (prompt + delayed) fission spectra for U-235, U-238 and Pu-239. These data, contained in the MATJEFF31.BOLIB package, are available in tabulated form as in the VITJEFF31.BOLIB library package. On the contrary the VITAMIN-B6, VITJEF22.BOLIB /9/ and MATJEF22.BOLIB /10/ similar library packages contain in tabulated form only the prompt components.

MATJEFF31.BOLIB is a pseudo-problem-independent library based on the Bondarenko /11/ (f-factor) method for the treatment of neutron resonance self-shielding and temperature effects. The library contains 176 nuclides at 4 temperatures, obtained for the most part with 6 to 8 values for the background cross section.

Thermal scattering cross sections were processed at all temperatures available in the JEFF-3.1 thermal scattering law data file for 6 additional bound nuclides (H-1 in light water (H-H2O), H-1 in polyethylene (H-CH2), H-1 in zirconium hydride (H-ZrH) (not contained in VITAMIN-B6, VITJEF22.BOLIB and MATJEF22.BOLIB), H-2 in heavy water (H2-D2O), C in graphite (C-GPH) and Be in beryllium metal (Be-TH)).

From MATJEFF31.BOLIB it is easily possible to generate, with the use of the TRANSX code, working libraries of collapsed and self-shielded cross sections in GOXS or FIDO-ANISN format for calculations with the DOORS /12/, DANTSYS /13/ and PARTISN /14/ deterministic transport systems and the MORSE /15/ Monte Carlo code.

8. RELATED OR AUXILIARY PROGRAMS

To obtain collapsed and self-shielded cross section working libraries in various formats (e.g. GOXS and FIDO-ANISN) for the specific applications an updated version of the PSR-0317 TRANSX 2.15 code is needed which was developed in ENEA-Bologna. In particular this revised version can produce GOXS binary data files in double precision and can perform the self-shielding for damage-energy cross sections and KERMA factors. The cited updating of TRANSX-2.15 is included in this package.
