1. NAME AND TITLE
MUSCAT: Calculation of Neutron Currents in Spherical and Cylindrical Cavities by Means of
General Atomic, San Diego, California.
OECD Nuclear Energy Agency Data Bank, Gif-sur-Yvette, France.
3. CODING LANGUAGE AND COMPUTER
FORTRAN IV; IBM 360/370.
4. NATURE OF PROBLEM SOLVED
MUSCAT is a program for computing the incident scattered neutron currents as a function of
position within the following cavities: 1) cavity formed by two truncated concentric spheres, 2)
cavity between two concentric circular cylinders, and 3) cylindrical cavity.
5. METHOD OF SOLUTION
In the analysis, the concept of view factors has been utilized. The view factor is defined as the fraction of neutrons, leaving a surface in all directions, which is intercepted by another surface or surfaces.
MUSCAT presents a compilation of the view factors and a description of the code system for
the case of two concentric cylinders and the case of a cylindrical cavity.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
No study has been made by RSIC of typical running times for MUSCAT.
8. COMPUTER HARDWARE REQUIREMENTS
The code was designed to run on the IBM 7044 and the IBM 360/370.
9. COMPUTER SOFTWARE REQUIREMENTS
MUSCAT requires an IBM FORTRAN IV compiler.
