Advanced modelling

Kemakta employs and develops models to address questions regarding the impact of various processes on the transport of substances, including in connection with safety analyses for the final disposal of spent nuclear fuel. We also apply modeling to investigate other environmental issues, such as gas phase transport of volatile substances and the impact on recipients from process water discharges.

Our goal is always to develop efficient solutions that are transparent, well-founded, and provide a deepened understanding of controlling processes. We offer tailored, traceable modeling services based on the latest scientific developments, focusing on:

Some examples include the impact of electric fields on the transport of charged particles and corrosion of steel in a deep repository in the bedrock, reactive transport modeling of alkaline water in rock fractures (spread of alkaline plume), sorption processes with site-specific and chemistry-dependent distribution coefficients (smart Kd), chemical/physical weathering of concrete barriers in the repository, chemical interaction between organic substances and concrete, and transport of chlorinated aliphatics from groundwater to indoor air.

Our skilled modelers use various simulation tools, including Comsol Multiphysics, DarcyTools, PhreeqC, Phast, Visual Minteq, Crunchflow, Matlab, Python and ToughReact.
