The PSI Laboratory for Simulation and Modelling develops numerical and computational capabilities for advanced nuclear systems, advanced particle accelerators, reacting and non-reacting fluid dynamics.
Topical areas
The topical areas of the Laboratory for Simulation and Modelling covers a broad spectrum of scientific disciplines such as
La simulation: le troisième pilier de la science
Des chercheurs de l’Institut Paul Scherrer PSI simulent et modélisent de grandes installations de recherche, mais aussi certaines expériences, par exemple en sciences des matériaux et en sciences de la vie. Andreas Adelmann, chef du Laboratoire de simulation et modélisation, explique comment ils procèdent.
Modéliser et simuler: un bon retour sur investissement
En combinant théorie, modélisation et calculs à haute performance, les chercheurs du Laboratoire de simulation et modélisation de l’Institut Paul Scherrer PSI résolvent les problèmes les plus complexes. De puissants ordinateurs leur permettent de simuler aussi bien les molécules les plus minuscules que les grandes installations de recherche.
Horizon 2020 project SAMOSAFER granted
The EU Horizon 2020 program granted 3.5 million Euros to the research and innovation project SAMOSAFER, where PSI is one of the 14 project partners. The total budget of the project, inclusive own and in-kind contributions, is 4.5 million Euros. The aim of SAMOSAFER project is to develop and demonstrate new safety barriers and a more controlled behaviour in severe accidents of the Molten Salt Reactor (MSR). Three groups at PSI will be involved in the project: the LSM groups for Advanced Nuclear Systems (ANS) and Multiscale Materials Modelling (MMM) and the Severe Accidents Research group (Sacre) of LRT, focusing on redistribution of the source term in the fuel treatment unit of MSR and assessment and reduction of radionuclide mobility during accidental conditions.
