Dieser Inhalt ist nicht auf Deutsch verfügbar.Nuclear Energy and Safety Research Division
Based on this infrastructure and the know-how of its collaborators the Division is involved in three main topics of research: Safety of currently operating light-water reactors, safety characteristics of future reactor concepts and related fuel cycles, and long-term safety of deep geological repositories for nuclear wastes of all kind.
The work is being done on behalf of the Federal Government and in close cooperation with the Swiss nuclear utilities, the national waste management organization, Nagra, and the national regulatory authority, ENSI. It also includes scientific services for the nuclear power plants. Most of the research is connected with international projects on a multi- or bi-national cooperation basis.
Net-Zero CO2 emissions scenarios for Switzerland

«Price tags» of the Swiss energy transition
NZZ am Sonntag has picked up this highlight in its issue on March 7th, 2021: The highlight refers to the analysis performed in SCCER Joint Activity Scenarios and Modelling, where PSI-LEA performed the analysis of the energy transition pathways.
Analysis of a large-scale turbulent round jet
The entire study is an investigation into the self-similarity behavior [1] of first and second order statistical quantities derived from a large-scale jet flow taken from one of the experiments in the PANDA facility using the Proper Orthogonal Decomposition (POD).
What is presented, are the merits, the potential and the characteristics of the corresponding underlying POD analysis. Proper Orthogonal Decomposition (POD) is a mathematical framework to extract large-scale structures which are otherwise eventually masked by the complexity of the fully turbulent flow; example: the meandering of a jet which is not so obvious for the original data.
Two scenarios for superconductivity in CeRh2As2
CeRh2As2, a nonsymmorphic heavy fermion material, was recently reported to host a remarkable temperature versus z-axis magnetic-field phase diagram with two superconducting phases. In this material, the two inequivalent Ce sites per unit cell, related by inversion symmetry, introduce a sublattice structure corresponding to an extra internal degree of freedom. In this work, we propose a classification of the possible superconducting states in CeRh2As2 from the two Ce-sites' perspective.
“Without these technologies, we will hardly achieve our climate targets”
To achieve carbon neutrality, technologies need to be deployed which remove carbon dioxide from the atmosphere.
Improving the resilience of Switzerland’s energy supply
The SURE research project is up and running.
Safely stored for a million years
Switzerland plans to construct a deep repository for its radioactive waste. There are three potential locations, and data obtained by PSI researchers can aid in selection of the best one.
Switzerland's energy transition
Can Switzerland, as planned, reduce its CO2 emissions to zero by 2050? What is needed to achieve this? What could it cost?
Watching receptor proteins changing shape
In our bodies, G protein-coupled receptors mediate countless processes. PSI researcher Ramon Guixà talks about how he brings those receptor molecules to life on the computer screen.
New blueprint for more stable quantum computers
PSI researchers have shown how faster and better defined quantum bits can be created. The central elements are magnetic atoms from the class of so-called rare-earth metals, selectively implanted into the crystal lattice of a material.
