Package-ID     Orig.Computer                       Test Computer
NEA-0310/02    IBM 370 series                      IBM 370 series

3. NATURE OF PHYSICAL PROBLEM SOLVED - One-dimensional, time dependent fission product diffusion in a temperature field, in slab, cylinder, or spherical geometry, taking one gaseous precursor into account. Transients are calculated too.


4. METHOD OF SOLUTION - Finite difference method.


5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM - 30 time steps, 40 mesh points, 30 evaporation boundaries. Temperatures are not automatically evaluated.


6. TYPICAL RUNNING TIME - 20 mesh points, three evaporation boundaries, one transient, 29 time steps. 22.9 seconds CPU-time, (2.09 minutes execution time) on the IBM 360/75.
