3. DESCRIPTION OF PROBLEM OR FUNCTION
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
FORMAT: TEMPEST and MUFT
NUMBER OF GROUPS: 246 thermal groups in TEMPEST format and 54 fast groups in MUFT format. From this library, the program SPOTS4 genera- tes a 172-54 group library as input to the code LEOPARD.
NUCLIDES: H, O, Zr, C, Fe, Ni, Al, Cr, Mn, U, Pu, Th, Pa, Xe, Sm, B and D.
ORIGIN: ENDF/B-4
WEIGHTING SPECTRUM: 1/E + U235 fission spectrum.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Data library of thermal and fast neutron group cross sections to generate input to the program LEOPARD. The data is based on ENDF/B-4 and consists of two parts:
(1) 246 thermal groups in TEMPEST format.
(2) 54 fast groups in MUFT format.
From this library, the program SPOTS4 generates a 172-54 group libr- ary as input to the code LEOPARD (NESC0279).
