The department Hotlab (AHL) is the responsible operator and primary user of the Hotlab nuclear facility – a unique experimental installation in Switzerland dedicated to the examination of highly radioactive materials. As a central scientific infrastructure, it plays a vital role in nuclear safety research.
AHL was established on January 1, 2008, following the restructuring of the former “Laboratory for Materials Behaviour” (LWV), which was split into the Department Hotlab (AHL) for operations and service infrastructure, and the Laboratory for Nuclear Materials (LNM) for materials science research.
The current organizational structure was updated in early 2016 to streamline workflows and enhance support for all users of the facility. AHL consists of five specialized groups:
• Building Systems Operation (BGT) – responsible for technical systems and media supply
• Hot Cell Experiments (HZE) – conducting experiments in shielded cells
• Radioactive Materials Analytics (ARM) – comprehensive analysis of highly active samples
• Radioactive Materials Post-Processing (NRM) – handling, packaging, and disposal of materials
• Operations, Administration and Safety (BAS) – organization, documentation, and safety management
Our primary mission is to deliver high-level analytical services to both internal and external partners, including Swiss nuclear power plants, nuclear fuel manufacturers, regulatory bodies, and national and international research groups such as the laboratories of the PSI Center NES.
We are committed to advancing the safe and sustainable use of nuclear technology by providing state-of-the-art infrastructure, deep expertise, and the highest safety standards.
The quality of our work is based on decades of experience, modern technology, and a strong commitment to precision, reliability, and safety – in both our analytical services and the daily operation of the facility.
