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
