The Hotlabor at the Paul Scherrer Institute in Villigen has been in operation for 60 years, examining radioactive materials, including nuclear fuel rods. Highly secure with thick concrete and lead walls, this lab employs specialized technology to safely analyze and process radioactive samples. Researchers use remote handling devices in ‘hot cells’ to ensure safety while conducting investigations into potential damage to fuel rods. The future of the Hotlabor depends on the ongoing operation and safety of nuclear power in Switzerland.
