3. DESCRIPTION

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
FORMAT: ANISN

 

NUMBER OF GROUPS: 100 neutron, 21 gamma ray

 

NUCLIDES: Ni, Cr, Fe, Mn, Co, Cu, He, C, O, Al, Pb, Li, B, H, Be, V, Nb, Ti, F, Si, Mg, K, Na, N, Mo, Zr, U, P, S, Sn, Cl, Ca, Np, Pu, Au, W, Ta, Th, D.

 

ORIGIN: ENDF/B-IV

 

WEIGHTING SPECTRUM: 1/E weighted for neutron energies exceeding 0.345 eV, below this energy a Maxwellian distribution peaked at 800K is used. The photon interaction cross sections are flat weighted.

 

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
This multigroup library is intended for use in neutronics calculations for the conceptual designs of the Experimental Power Reactor (EPR) and other fusion reactor models.

 

The data is in ANISN format, and has a coupled 100 neutron, 21 gamma ray energy group structure. The neutron groups include the 99 GAM- II epithermal and fast groups, together with a thermal group. All data sets exist for a P8 order of Legendre expansion, except those for tungsten which are P3.

 

Neutron and photon production cross sections are 1/E weighted for neutron energies exceeding 0.345 eV; below this energy a Maxwellian distribution peaked at 800 K is used. The photon interaction cross sections are flat weighted.

4. METHODS

Selected modules of the AMPX system were used to generate the data sets from the latest ENDF/B data.

The coupled 100 energy group neutron and 21 energy group gamma-ray ANISN-formatted cross section library has been modified by the addition of Si, Mg, K, Na, N, Mo, NatZr, 235U, 238U, 31P, 32S, Sn, Cl, Ca, 182W, 183W, 184W, 186W, NatW, and Nb (ENDF/B-IV) cross sections, by the addition of data sets containing 10B(n,t)2α, 10B(n,α), 11B(n,t), 11B(n,α), 6Li(n,t), 6Li(n,t) Hot Kerma Factors, and 7Li(n,n't) cross sections. The 100 energy group neutron master cross section library was modified by the addition of Nb, Zr, Ka, K, Mo, Si, Mg, N, Cl, Ca, 31P, 32S, Sn, 235U, 238U, 182W, 183W, 184W, and 186 W data sets.
