3. DESCRIPTION OF PROBLEM OR FUNCTION


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

  FORMAT: ANISN, DOT and MORSE

  NUMBER OF GROUPS: EURLIB -> 100 neutron and 20 gamma groups
collapsed in: EURLIB-LWR-45/16 -> 45 neutron and 16 gamma groups
              EURLIB-LWR-15/5  -> 15 neutron and  5 gamma groups.

NUCLIDES: EURLIB -> H, He, Li-6, Li-7, B-10, B-11, C, O, Na, Al, Si, Ca, V, Cr, Mn, Fe, Ni, Cu, Nb, W-182, W-183, W-184, W-186, Pb, U-235, U-238, Pu-239
EURLIB-LWR -> H, C-12, O, Na, Al, Si, Ca, Cr, Mn, Fe, Ni, Zr, U-235, U-238.

  ORIGIN: ENDF/B-IV

WEIGHTING SPECTRUM: In Fe, U-235, U-238 and Pu-239, narrow-resonance weighting was applied below 0.825 MeV with a weighting function 1/(sigmaT*E), and fission-spectrum weighting above. For the other elements, only 1/E weighting was applied below  0.825 MeV. For the gamma groups, the resonance escape probability was used as weighting function.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
EURLIB is a coupled neutron-gamma multigroup constants library for shielding calculations. The group structure consists of 100 neutron and 20 gamma groups. The basic microscopic cross sections have been taken from ENDF/B-4. Anisotropy is considered in P5 approximation. The following elements are included:
H, He, Li-6, Li-7, B-10, B-11, C, O, Na, Al, Si, Ca, V, Cr, Mn, Fe,  Ni, Cu, Nb, W-182, W-183, W-184, W-186, Pb, U-235, U-238, Pu-239.
The coupled multigroup EURLIB library is collapsed into few group structures for typical designs of LWR, LMFBR, gas cooled and thermonuclear reactors. The libraries produced are:
EURLIB-LWR-45/16, 45 neutron and 16 gamma groups, and
EURLIB-LWR-15/5, 15 neutron and 5 gamma groups.
The elements considered in these two libraries are H, C-12, O, Na, Al, Si, Ca, Cr, Mn, Fe, Ni, Zr, U-235, U-238.

4. METHOD OF SOLUTION

The data for the EURLIB library were generated  using AMPX-1, and are therefore available in FIDO format.
In Fe, U-235, U-238 and Pu-239, narrow-resonance weighting was applied below 0.825 MeV with a weighting function 1/(sigmaT*E), and  fission-spectrum weighting above. For the other elements, only 1/E weighting was applied below 0.825 MeV.
For the gamma groups, the resonance escape probability was used as weighting function.
EURLIB-LWR-45/16 and EURLIB-LWR-15/5 data were produced from EURLIB  library by applying the automatie collapsing scheme AGRUKO to the radial PWR shielding design benchmark.
