1. NAME AND TITLE

S1CALC: A Multigroup Thermal Neutron Scattering Law Data Generator for Hydrogen and Deuterium.

AUXILIARY ROUTINE

RISLEY

2. CONTRIBUTOR

United Kingdom Atomic Energy Authority, Winfrith, Dorchester, Dorset, England, through the OECD NEA Data Bank, Gif-sur-Yvette, France.

3. CODING LANGUAGE AND COMPUTER

Fortran IV and Assembler Language; IBM 360/370.

4. NATURE OF PROBLEM SOLVED

S1CALC prepares multigroup thermal neutron scattering data for hydrogen in light water and deuterium in heavy water.

5. METHOD OF SOLUTION

The computations are done in the range of 293oK to 620oK. The data for hydrogen in light water are based on Nelkin's model and for deuterium in heavy water on Honeck's model.

6. RESTRICTIONS OR LIMITATIONS

None noted.

7. TYPICAL RUNNING TIME

No study has been made by RSIC of typical running times for S1CALC.

8. COMPUTER HARDWARE REQUIREMENTS

S1CALC is operable on the IBM 360/370 computers.

9. COMPUTER SOFTWARE REQUIREMENTS

Fortran IV and Assembler Language compilers are required.
