3. DESCRIPTION OF PROGRAM OR FUNCTION


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

  LAFPX-IV
  ========

  FORMAT:

  NUMBER OF GROUPS: 154-group fission-product cross sections.

NUCLIDES: Ge, As, Se, Br, Kr, Rb, Sr, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, In, Sn, Sb, Te, I, Xe, Cs, Ba, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er.

  ORIGIN: ENDF/B-IV

  WEIGHTING SPECTRUM:
from 10**5 eV to 0.625 eV    -> mid-life PWR thermal spectrum
from 0.625 eV to 3.*10**4 eV -> spectrum from MC**2 "ultrafine"
multigroup calculations + resonances from 3.*10**4 eV to 3.*10**6 -> spectrum from MC**2 "fine"
multigroup calculations + resonances from 3.*10**6 eV to 10**7 eV -> shape of a fission spectrum
from 10**7 eV to 1.257*10**7 -> 1/E
from 1.257*10**7 to 1.557*10**7 -> velocity exponential fusion peak
from 1.557*10**7 to 2*10**7  eV -> 1/E

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
LAFPX-V is a data library of 154-group fission-product cross sections processed from ENDFB-V with a typical light-water reactor flux spectrum and temperature.

4. METHOD OF SOLUTION

The library has been generated from the 181 nuclides of the 824 nuclide ENDF/B fission product library using the code NJOY (PSR-0171).

6. TYPICAL RUNNING TIME

The cross-section collapsing program TOAFEW-V has been run by NEA-DB on both CDC CYBER 740 and VAX-11/780. Execution times for the test cases were: 200 CPU seconds for cases 1 and 2; 333 CPU seconds for case 3.
