Development of a Special COMSOL® Interface Based on an Alternative Model for Bentonite Re-Saturation

Michael Kröhn1, Lars Fromme2
1GRS gGmbH, Braunschweig, Germany
2Hochschule Bielefeld – University of Applied Sciences and Arts (HSBI), Faculty of Engineering and Mathematics, Bielefeld, Germany

Bentonite is a versatile material that is, among other things, envisaged in most countries worldwide for use in radioactive waste repositories to protect the waste canisters against groundwater. The thermo-hydro-mechanically (THM) coupled process of bentonite saturation is commonly based ... Read More

Laser cutting process is usually employed in machining process, however it is also applied for dismantling nuclear facilities. Contrary to mechanical processes where tools wear out quickly and are often renewed, laser cutting process is a contactless approach, therefore there is no ... Read More

Simulating Condensate Layers on Thermal Bridges in Train Walls

Felix Lüönd1, Thomas Graf1, Marc Achermann1
1Lucerne University of Applied Sciences

Using the COMSOL Multiphysics® software with the Heat Transfer Module, we calculated coupled heat and moisture transport to simulate the amount and distribution of condensed moisture in a train wall, with a special focus on the surface of thermal bridges. We tested two approaches to ... Read More

Investigations on Talik Formation During Changes to Cold Climates

K.-P. Kröhn1
1GRS gGmbH, Braunscheig, Germany

Over the past million years, several cold ages have occurred and thereby caused perma-frost conditions basically all over the present area of Germany. Since in Germany the safe-ty of a nuclear waste repository legally needs to be investigated for a period of one million years, the ground ... Read More
