Your Partner for Radioactive Material Examinations
The nuclear facility Hotlab (HL) of PSI is operated by the Department Hot Laboratory (AHL), which is assigned to the Nuclear Energy and Safety Division (NES) as an independent organizational unit.
The PSI Hotlab is the only Swiss laboratory authorised by the Swiss safety authorities to handle large quantities of radioactive materials including commercial as well as experimental nuclear fuel.

New method for inspecting fuel rods
PSI researchers have successfully used a new method to analyse the cladding tubes of spent fuel rods from nuclear reactors at very high resolution for the first time. They found that the cladding tubes remained leak-tight.
Exploring Molten Salt Technology
Molten salt reactors are being explored as a possible approach to nuclear energy. This animation takes you inside the reactor to explore its core processes, safety characteristics, potential advantages and challenges that still need to be addressed.
Project BALDER at the RRFM-2026
At this year’s European Conference on Research Reactors (RRFM-2026), held in conjunction with the International Radioisotope Supply Chain Meeting (IRIS) and the SMR/AMR Developers’ Meeting (SMaRRt) in Leiden, the presentations on the status of our BALDER project generated significant international interest.
