3. NATURE OF PHYSICAL PROBLEM SOLVED

Starting with a top boundary source, volume distributed first collision sources in r-z geometry are calculated.
top ]
4. METHOD OF SOLUTION:  Numerical integration of the integral transport equation.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The program uses dynamic storage allocation technique. Therefore, restrictions are only imposed by the main storage and extended core storage (ECS) available.
