3. NATURE OF PHYSICAL PROBLEM SOLVED

MERCURE-3/PC performs three- dimensional gamma shielding calculations around extended gamma sources. These may be even non-homogeneous.
top ]
4. METHOD OF SOLUTION

The algorithm of the code is the point kernel integration model combined with buildup calculations. The geometry can be described analytically using linear and quadratic surfaces of any type. A standard gamma cross section library is provided with the code.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

To make possible the  solution of large problems, all the problem size-dependent arrays are declared using symbolic constants. The default values are sufficient for most of the practical problems (e.g. 100 space elements; 100 equations; 300 surface elements; 40 materials; 25 energy groups, etc.); the code uses in this case only 200-250 Kbytes of memory, depending on the compiler used. If the problem is  very large, the symbolic constants have to be modified, and the code has to be compiled using the Lahey F77L3 (protected mode) compiler.

6. TYPICAL RUNNING TIME

The running time of the sample problem is 1 minute on a PC/80486 machine (33 MHz, 6.4 MIPS, protected mode), which corresponds to 15-30 minutes on a PC/80286/80287.
NEA-0194/02
NEA-DB ran the test cases included in this package on a PC/80486 with 66 MHz. Elapsed times were 25 seconds for MERCLIBR; and 55 seconds for MERCURE-3.

8. RELATED AND AUXILIARY PROGRAMS

For complex geometries it is preferable to use MERCURE-4.
