1. NAME AND TITLE
RHEIN: Reactor Code System for Neutron Physics Calculation.
Zentralinstitut Fur Kernforschung Rossendorf, Dresden, Germany, through NEA Data Bank, Gif-sur-Yvette Cedex, France.
3. CODING LANGUAGE AND COMPUTER
FORTRAN IV; IBM 3090, ES-1055.
4. NATURE OF PROBLEM SOLVED
RHEIN is a modular reactor code system for neutron physics calculation.
5. METHOD OF SOLUTION
The calculation routines can be used for the following problems: calculation of cross section sets for infinite medium; zero-dimensional spectrum calculation in diffusion, P1 or B1 approximation; one-dimensional calculation in diffusion, P1 or collision probability approximation; two-dimensional diffusion calculation; cell calculation; zonewise homogenized group collapsing within zero, one or two-dimensional model.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
On the IBM 3090, test case 1 took 7 seconds; test case 2 took 2 seconds; test case 3 took 66 seconds.
8. COMPUTER HARDWARE REQUIREMENTS
RHEIN runs on the IBM 3090 and ES-1055 computers.
9. COMPUTER SOFTWARE REQUIREMENTS
The code was written in FORTRAN IV. On the IBM 3090, VS FORTRAN 2.1.1 (with the FORTRAN 66 option) was used under the MVS/XA operating system.
