The safety of Deep Geological Repositories (DGR) for spent nuclear fuel is a highly important issue, and should be assessed using the Best Available Technology (BAT). With this motivation in mind, Amphos 21 has recently developed a numerical tool, denoted as iDP (interface between DarcyTools and PFL... Read more...

This post is intended to illustrate how to calculate the water age in a volume (3D model) or surface (2D model) based in the methodology proposed by Goode D.J. (1996).

The implementation in Comsol Multiphysics can be done in two different ways, namely by means of transient or steady-state simula... Read more...

A large-scale, long-term simulation of the hydrogeochemical behaviour of fractured rocks is shown in this post. The simulations are performed with iCP, the COMSOL-Phreeqc interface, that allows performing 3D reactive transport simulations in discrete fractures accounting for matrix diffusion (as a 4...

Heap leach pads constitute a common practice in the mining industry. In their design and management it is not common to take into account criteria based on coupled hydro-mechanical-chemical (HMC) processes, and these are of paramount importance for two reasons: (i) they could play an important role ...

Distribution coefficients, also known as Kd values, are lumped parameters that contain information about the radionuclude-soil/rock interaction processes. These values are of paramount importance in performance assessment studies of nuclear waste repositories as they are used to predict the fate ... Read more...
