DLC-0119 ZZ-HILO86.

1. NAME OR DESIGNATION OF PROGRAM:  ZZ-HILO86.

3. DESCRIPTION OF PROGRAM OR FUNCTION


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

  FORMAT: ANISN, DORT, MORSE

  NUMBER OF GROUPS: 66 Neutron, 22 Gamma-Ray

NUCLIDES: H, B-10, B-11, C, N, O, Na, Mg, Al, Si, S, K, Ca, Cr, Fe  Ni, W, Pb.

  ORIGIN: ENDF/B-IV + ENDF/B-V

  WEIGHTING SPECTRUM: 1/E used for neutron energies >/ 19.6 MeV

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
For a variety of applications (accelerator shielding, the use of neutrons in radiotherapy, radiation damage studies, etc.) it is necessary to carry out transport calculations involving medium-energy neutrons. ZZ-HILO86 is a group cross section library with 66 Neutron, 22 Gamma-Ray groups for Neutron Energies up to 400 MeV, in the form needed for the CCC-254/ANISN-ORNL and CCC-484/DORT discrete ordinates codes and for the CCC-474/MORSE-CGA Monte Carlo code.
Below 19.6 MeV, the library consists of data derived from DLC-113/VITAMIN-E (ENDF/B-IV) except for sulfur and lead. Above that energy, differential elastic cross section data have been chosen so that the total, i.e., elastic + nonelastic, cross sections agree with experimental data. The library is P5. Data are provided for: H, 10B, 11B, C, N, O, Na, Mg, Al, Si, S, K, Ca, Cr, Fe, Ni, W, Pb.

4. METHOD OF SOLUTION:

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM:

6. TYPICAL RUNNING TIME

On a PC 386, the program BCD2BIN converted the HILO86 BCD data into binary form in about 7 minutes.

NEA-DB executed the test case of the ASCII-to-binary conversion program on a 66-MHz PC/80486 in 40 seconds.

7. UNUSUAL FEATURES OF THE PROGRAM:

8. RELATED AND AUXILIARY PROGRAMS

   BCBN: Converts ANISN card-image data to binary format.
This cross-section library for multigroup transport calculations for neutron and photon energies up to 400 MeV and 20 MeV, respectively,  is an upgrade of a similar library, DLC-41/VITAMIN-C (ENDF/B-IV).
