1. NAME AND TITLE
MUSPALB: Albedo Calculation of Multigroup Spectra of Neutrons Transmitted Through
Multilayer Slab Shielding.
Central Research Institute for Physics, Budapest, Hungary.
3. CODING LANGUAGE AND COMPUTER
ICL FORTRAN IV; ICL 1905.
4. NATURE OF PROBLEM SOLVED
MUSPALB solves multigroup neutron transmission, reflection, and internal spectra problems in
multilayered slab geometry consisting of non-multiplying media. Transmitted and reflected spectra
5. METHOD OF SOLUTION
Albedo operator or transmission matrix formalism is applied in non-multiplying media with slab
geometry and multigroup energy treatment. The code uses the Peirls integral equation method for
the albedo matrix. The 26-group cross sections of Abagyan are used. Multilayered systems can be
computed from matrices calculated for basic layers.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
No study has been made by RSIC of typical running times for MUSPALB.
8. COMPUTER HARDWARE REQUIREMENTS
MUSPALB was designed for the ICL 1905 computer.
9. COMPUTER SOFTWARE REQUIREMENTS
A FORTRAN IV compiler is required.
