3. DESCRIPTION

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

FORMAT: GAM-II group structure and ANISN

 

NUMBER OF GROUPS: 100-group cross sections.

 

NUCLIDES: H, He, Li, Be, B, N, O, F, Na, Al, Si, P, S, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Y, Zr, Nb, Mo, Tc, Ru, Ag, Sn, Cs, Hf, Ta, W, Re, Au, Pb.

 

ORIGIN: derived from ENDF/B, or calculated at Brookhaven National Laboratory.

 

WEIGHTING SPECTRUM: 1/E except near 14 MeV where a thermally broadened fusion peak, assuming a temperature of 20 MeV, is employed

 

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

This data library contains 100- group cross sections, with GAM-II group structure, for 421 neutron activation reactions with fusion reactor structural and coolant materials. The weighting function is 1/E except near 14 MeV where a thermally broadened fusion peak, assuming a temperature of 20 MeV, is employed. The library also contains half life information for the activated nuclei.

4. METHODS

The thermal group cross sections were calculated from the 2200 m/s value, when available, otherwise from the group 99 value. The majority of the non-thermal cross sections were derived from pointwise data derived from ENDF/B, or calculated at Brookhaven National Laboratory using the nuclear systematics code THRESH. These were converted to multigroup from using the codes ETOG and NJOY.

8. RELATED OR AUXILIARY PROGRAMS

The retrieval program RESOLVE can create activity cross section tables in a format suitable for input to the one-dimensional transport code ANISN. These tables have a length of 103, which matches the size of the DLC-2 100-group library.

The initial release of the library in 1974 included 88 activation reactions. The second version extended this number to 399, and this third version to 421.
