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, 6Li, 7Li, 10B, 11B, C, O, Na, Al, Si, Ca, V, Cr, Mn, Fe, Ni, Cu, Nb, 182W, 183W, 184W, 186W, Pb, 235U, 238U, 239Pu
EURLIB-LWR -> H, C-12, O, Na, Al, Si, Ca, Cr, Mn, Fe, Ni, Zr, 235U, 238U.
ORIGIN: ENDF/B-IV
WEIGHTING SPECTRUM: In Fe, 235U, 238U and 239Pu, narrow-resonance weighting was applied below 0.825 MeV with a weighting function 1/(∑TE), 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 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:
The data for the EURLIB library were generated using AMPX-1, and are therefore available in FIDO format.
In Fe, 235U, 238U and 239Pu, narrow-resonance weighting was applied below 0.825 MeV with a weighting function 1/(∑TE), 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 automatic collapsing scheme AGRUKO to the radial PWR shielding design benchmark.
