The 4th European Nuclear Competition for Secondary Schools was a unique opportunity to showcase the creativity of secondary school students and to explore the exciting world of nuclear science.

The ETSON JSP Workshop 2025 brought together young professionals and experts from across Europe to share knowledge, exchange experiences, and discuss key topics in nuclear safety. 

The enrichment, geometry and overall configuration of the gas-cooled ALLEGRO reactor core resulted in an undesirable effect in the form of significant changes in reactivity even with a small movement of the control rods. Consequently, new technical solution with steel half-cylinder device (HCD) was proposed.

The UK Office for Nuclear Regulation has re-nominated Amentum’s Regulatory Support Directorate as the UK member of ETSON under the name RSD.

The Hotlab at the Paul Scherrer Institute PSI is a unique experimental facility for analysing highly radioactive materials – its 60th anniversary marks a milestone not only in the institute’s history but also in the history of Swiss nuclear technology as a whole.

Prof. dr. Leon Cizelj is the new Acting Director of the Jožef Stefan Institute.

Be it software updates, cloud services or external analysis platforms - modern IT systems rely on a large number of digital service providers. What brings efficiency also harbours new risks: This is because attackers can penetrate deep into well-protected systems unnoticed via an inadequately protected supply chain - even in safety-critical areas such as nuclear engineering. A new GRS research project looks at how such attacks unfold, which systems are particularly at risk, and how operators can protect themselves better.

The UK Government has established a Nuclear Regulatory Task Force to examine the regulatory approach to civil and defence projects.

Copenhagen Atomics, a Danish molten salt reactor developer, and the Paul Scherrer Institute PSI, Switzerland’s largest research institute for natural and engineering sciences, have signed a large-scale experimental collaboration agreement.

In recent years, drones - also known as unmanned aerial vehicles, systems or devices (UAV, UAS or UAD for short) - have become increasingly important.
