NEA-1668 ZZ-MCB-EAF99.

1. NAME OR DESIGNATION OF PROGRAM:  ZZ-MCB-EAF99.

3. DESCRIPTION OF PROGRAM OR FUNCTION

MCB-EAF99 is a continuous-energy activation cross section library in ACE format suitable for the MCB-1C and MCNP codes. Libraries for various materials were generated at six different temperatures, and cover the energy range up to 20 MeV.
FORMAT: ACE
NUMBER OF GROUPS: Continuous energy
NUCLIDES: Library includes elements with atomic numbers Z= 1 - 84, 86, 88 - 100 (i.e.: H, He, Li, Be, B, C, N, O, F, Ne, Na, Mg, Al, Si, P, S, Cl, Ar, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Br, Kr, Rb, Sr, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Pd, Ag, Cd, In, Sn, Sb, Te, I, Xe, Cs, Ba, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, Tl, Pb, Bi, Po, Rn, Ra, Th, Pa, U, Np, Pu, Am, Cm, Bk, Cf, Es, Fm).
TEMPERATURES: 300 K, 600 K, 900 K, 1200 K, 1500 K, and 1800 K.
ORIGIN: EAF-99
WEIGHTING SPECTRUM:

4. METHODS

The library was generated using the NJOY processing code. An example of the input data is provided.

6. TYPICAL RUNNING TIME

The ASCII-to-binary conversion can generally be accomplished within a few seconds, even for the large data files.

8. RELATED OR AUXILIARY PROGRAMS

MAKSF, which is distributed with CCC-700/MCNP4C, can be used to convert MCNP Type 1 data to Type 2 (binary). For use with the code MCB-1C the MAKXSF installation must be slightly modified.
