Abstract

DRBEM simulation of radionuclide transport near nuclear waste repository J. Perko and B. Sarler Laboratory for Fluid Dynamics and Thermodynamics, Faculty of Mechanical Engineering, University of Ljubljana, SI-1000 Ljubljana, Slovenia Abstract Numerical modelling and simulation represent essential tools for evalua- tion of the safety of nuclear waste repositories. The Dual Reciprocity Boundary Element method (DRBEM) is used in this paper to solve the Darcy-Brinkman equation, and coupled species transport equations of the Pu-241 decay chain near the hypothetic repository. For this purpose, the very recently developed unified DRBEM formulation for nonlinear coupled transport phenomena has been applied. Fully implicit time-discretization, Laplace equation fundamental solution weighting, scaled augmented thin plate spline based dual reciprocity transformation, and constant discontin- uous boundary elements are used for space-discretization in two dimensions. The simulations will be use
