Irina Gaus elected to Nagra’s Executive Board

Nagra's Board of Directors has appointed Irina Gaus as Head of the Optimisation Division and member of the Executive Board. She will take over her new responsibilities from 1st January 2023. With Irina Gaus, a proven leader and distinguished scientist is taking over the continuous improvement of the project of the century of deep geological disposal of radioactive waste.


Irina Gaus has worked for Nagra (National Cooperative for the Disposal of Radioactive Waste) since 2007. She is Nagra’s Head of Research and Development and is also responsible for interdisciplinary national and international projects. She has a doctorate in hydrogeology and is a recognised expert in the development of deep geological repositories. In her new role, Gaus will be responsible for optimising the repository project with a particular view to long-term safety, construction and cost.

Following the announcement of the siting proposal for the deep geological repository in September 2022, this project of the century will enter the licensing and construction planning phase. Nagra will now concentrate primarily on preparing the general licence application, which is to be submitted in 2024. At the same time, the coming years will be used to optimise the technical details of the repository. “By taking these steps, we can ensure that the best and most modern technology will be available to us when construction of the access facilities is scheduled to start around ten years from now,” explains Irina Gaus and adds: “We are working on developing a digital environment that combines all the analyses and evaluations related to safety, construction and cost. This will allow us to optimise the repository. I look forward to accepting this challenge together with my team. We will continue our research and keep learning – and eventually construct a state-of-the art repository.”

From 1st January 2023, Nagra’s Executive Board will consist of the following members:

Matthias Braun, CEO

Markus Fritschi, Deputy CEO

Maurus Alig, Coordinator Major Project Sectoral Plan Stage 3 / General Licences

Reto Beutler, Division Head Finance, Controlling & Human Resources

Irina Gaus, Division Head Optimisation

Philipp Senn, Division Head Communication & Public Affairs

Severin Wälchli, Division Head Planning & Construction

«The geology has spoken.» This was the justification for the siting proposal for Switzerland's deep geological repository. There is a lot of science behind this simple sentence. Lyesse Laloui, Full Professor and Director of the Soil Mechanics Laboratory at the EPFL Lausanne, talks about his motivation to make life better for us all, the research collaboration with Nagra and the role of science in the project of the century for a deep geological repository.

Nagra proposes “Nördlich Lägern” as the site for a repository

Nördlich Lägern is the safest site for a deep geological repository: here, the rock deep below the surface best confines the radioactive waste for a very long time. Nagra’s investigations demonstrate this. The siting proposal is an important milestone in the project of the century of deep geological disposal.
