3. DESCRIPTION OF PROBLEM OR FUNCTION

TRITMOD is a steady-state advection and cycling in underlying vegetation and soil from an atmospheric point source. Radial geometry is assumed. Tritium is assumed to be released to the atmosphere in both gaseous tritiated hydrogen and tritiated water vapor form.

[ top ]

4. METHOD OF SOLUTION

The steady-state dispersion equation is solved iteratively by integration from the furthest distance from the source back to the source.

[ top ]

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Steady-state
conditions and radial geometry are assumed.

[ top ]

6. TYPICAL RUNNING TIME

Running time is dependent on the radius of interest. Five minutes is a typical time for a 50 kilometer radius on an IBM360.

[ top ]

7. UNUSUAL FEATURES OF THE PROGRAM

TRITMOD takes into account the deposition of HT and the conversion of HT to HTO.
