3. DESCRIPTION OF PROBLEM OR FUNCTION

Calculation of the self- absorption of unscattered (gamma-) radiation from fuel assemblies which contain a regular arrangement of identical fuel rods.
top ]
4. METHOD OF SOLUTION

The point-kernel is integrated over the radiation sources, i.e. the fuel rods. A uniform mesh of integration points is used for each of the fuel rods.
top ]
5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM:  Number of fuel rods  is dynamically allocated.

6. TYPICAL RUNNING TIME

Execution of the test case on IBM 3081 required 55 CPU seconds.
