Overview
The Paul Scherrer Institut (PSI) is Switzerland's largest research institute for natural and engineering sciences, located in Villigen, Aargau. It is funded by the Swiss Confederation and operates under the Swiss Federal Institute of Technology (ETH) domain, focusing on civilian research in areas such as energy, materials science, and nuclear technology. PSI has historically operated research reactors, including the now permanently shutdown PROTEUS zero-power reactor, to support scientific advancements and nuclear safety studies. Globally, PSI is recognized for its contributions to neutron scattering research and its role in fostering sustainable energy solutions through non-commercial nuclear research.
Recent Developments
In the past 12-24 months, PSI has continued to advance its research in nuclear energy sustainability, focusing on safety and waste management solutions as part of Switzerland’s energy transition strategy. Notably, PSI has been involved in international collaborations under the European Union’s Horizon Europe program, contributing to projects on advanced nuclear materials and reactor technologies for civilian applications. Additionally, PSI has emphasized interdisciplinary research, integrating nuclear science with renewable energy studies to support Switzerland’s goal of carbon neutrality by 2050.
