Title:
|
ANALYTICAL STUDY IN 1D NUCLEAR WASTE MIGRATION
|
| |
|
Summary :
|
|
THE SIMULATION OF THE NUCLEAR WASTE MIGRATION PHENOMENA ARE GOVERNED MAINLY BY DIFFUSIVE-CONVECTIVE EQUATION THAT INCLUDES THE EFFECTS OF HYDRODYNAMIC DISPERSION (MECHANICAL DISPERSION AND MOLECULAR DIFFUSION), RADIOACTIVE DECAY AND CHEMICAL INTERACTION. FOR SOME SPECIAL PROBLEMS (DEPENDING ON THE BOUNDARY CONDITIONS AND WHEN THE DOMAIN IS CONSIDERED INFINITE OR SEMI-INFINITE) AN ANALYTICAL SOLUTION MAY BE OBTAINED USING CLASSICAL ANALYTICAL METHODS SUCH AS LAPLACE TRANSFORM OR VARIABLE SEPARATION. THE HYBRID GENERALIZED INTEGRAL TRANSFORM TECHNIQUE (GITT) IS A POWERFUL TOOL THAT CAN BE APPLIED TO SOLVE DIFFUSIVE-CONVECTIVE LINEAR PROBLEMS TO OBTAIN FORMAL ANALYTICAL SOLUTIONS. THE AIM OF THIS WORK IS TO ILLUSTRATE THAT THE GITT MAY BE USED TO OBTAIN AN ANALYTICAL FORMAL SOLUTION FOR THE STUDY OF MIGRATION OF RADIOACTIVE WASTE IN SATURATED FLOW POROUS MEDIA. A CASE TEST CONSIDERING 241AM RADIONUCLIDE IS PRESENTED. |
