3. NATURE OF PHYSICAL PROBLEM SOLVED

Determines complete fission product inventory for a reactor after a particular history of operating conditions taking into account the structure of the individual decay chains and also the effects of neutron capture.
top ]
4. METHOD OF SOLUTION

Each chain is fitted to a generalised decay scheme and the simultaneous differential equations, whose coefficient matrix is lower triangular, are solved.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

In its present form up to 100 reactor cycles may be examined but this may be readily increased.

6. TYPICAL RUNNING TIME

Less than 0.5 seconds/chain/mode of fission/ reactor cycle.
