3. DESCRIPTION OF PROGRAM OR FUNCTION

   
VITJEF22.BOLIB /1/ is a multigroup coupled (199 neutron groups + 42 photon groups) pseudo-problem-independent cross section library in AMPX /2/ format for nuclear fission applications. VITJEF22.BOLIB is based on the JEF-2.2 /3/ European nuclear data file and it was processed, through the NJOY /4/ and SCAMPI /5/ systems, in the VITAMIN-B6 /6/ group structure using the same parameters and calculation procedures.

ORIGINAL NUCLEAR DATA FILE: JEF-2.2

DATA PROCESSING SYSTEMS: NJOY-94.66 and SCAMPI

FORMAT: AMPX

NUMBER OF GROUPS: 199 neutron groups and 42 photon groups

THERMAL NEUTRON GROUPS: 36 groups below 5.043 eV with upscattering cross sections  

NEUTRON ENERGY RANGE: 1.0E-5 eV - 19.64 MeV

PHOTON ENERGY RANGE: 1.0 keV - 30.0 MeV

TEMPERATURES [K]: 300, 600, 1000, and 2100 (same values as in VITAMIN-B6)

BACKGROUND CROSS SECTIONS (SIGMA-ZEROs) [barns]:
  1, 10, 50, 100, 300, 1.0E+3, 1.0E+4,

4. METHODS

  
The ENEA-Bologna Nuclear Data Centre produced the VITJEF22.BOLIB library within the framework of a co-operation with specialists of the Obninsk Institute of Physics and Power Engineering (IPPE-Obninsk, Russian Federation). The VITJEF22.BOLIB library for nuclear fission applications was conceived as an European counterpart of the VITAMIN-B6 American library, based on the ENDF/B-VI Release 3 nuclear data file. The present library has in particular the same group structure and the general features as VITAMIN-B6 and was produced using the same data processing methodologies, based on the NJOY-94.66 and SCAMPI data processing systems.
  
VITJEF22.BOLIB /1/ in AMPX format (NEA-1699/01) and MATJEF22.BOLIB /7/ in MATXS format (NEA-1740/01) are twin libraries produced in ENEA-Bologna and derived from the same set of cross section files in GENDF format, obtained from NJOY-94.66.
  
VITJEF22.BOLIB is a pseudo-problem-independent library based on the Bondarenko /8/ (f-factor) method for the treatment of neutron resonance self-shielding and temperature effects. The library contains 133 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 JEF-2.2 thermal scattering law data file for 5 additional bound nuclides (H-1 in light water (H-H2O), H-1 in polyethylene (H-CH2), H-2 in heavy water (H2-D2O), C in graphite (C-GPH) and Be in beryllium metal (Be-TH)).
  
From VITJEF22.BOLIB it is possible to generate easily, through further proper data processing with the AMPX or SCAMPI systems, working libraries of self-shielded cross sections in AMPX or FIDO-ANISN format to be used in transport calculations with the AMPX, SCAMPI, SCALE, DOORS, DANTSYS and MORSE systems.

Modules from PSR-0352 SCAMPI, which is a subset of PSR-0315 AMPX-77 with some improvements from CCC-0545 SCALE-4.3, are needed to produce collapsed and self-shielded cross section working libraries for the specific applications.
