• A three-dimensional radionuclide migration model has been developed by using of the direct-simulation method. The phenomena taken into account are radioactive decay, con-vection and dispersion in the ground water and sorption and desorption in the geologic media. Decay chain is represented by particle's character change using decay probability. Smooth-ing method is proposed to make an even distribution of particles and to obtain the exact radioactive inventory. Numerical calculations of <SUP>245</SUP>Cm decay chain and <SUP>234</SUP>U decay chain in the single layered geologic media have been carried out, and reasonable results have been obtained in comparison with INTRACOIN study. Nuclide migration of <SUP>237</SUP>Np decay chain in the three-layered geologic media were examined and shown graphically.
