NEUTRON WEIGHTING SPECTRUM:
  
Corresponding to the IWT=4 input option in the GROUPR module of NJOY:
from 1.0E-5 eV to 0.125 eV -> Maxwellian thermal spectrum (kT = 0.025 eV)
from 0.125 eV to 820.8 keV  -> '1/E' slowing-down spectrum
from 820.8 keV to 19.64 MeV -> fission spectrum (fission temperature = 1.273 MeV)
  
PHOTON WEIGHTING SPECTRUM:
  
Corresponding to the IWT=3 input option in the GAMINR module of NJOY:
'1/E' spectrum with a 'roll-off' at lower energies to represent photoelectric absorption and a similar 'drop-off' at higher energies corresponding to the Q-value for neutron capture.
  
The prompt neutron fission spectra for U-235, U-238 and Pu-239 are included in tabulated form in the package together with the neutron and photon group energy boundaries, the neutron and photon group lethargy boundaries and the neutron and photon group lethargy widths.
The neutron and photon energy weighting spectra in group representation are also included in the package.
Detector response functions are at present not included in the library package.  
  
VITJEF22.BOLIB was extensively tested /1/ on many thermal and fast criticality benchmark experiments.

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.
