The nuclear installations of the École Polytechnique Fédérale de Lausanne (EPFL) include the CROCUS research reactor, the CARROUSEL neutron experiment, the LOTUS neutron source, and the associated laboratories. These installations are part of the “Laboratoire de physique des réacteurs et de comportement des systèmes” (Laboratory for Reactor Physics and Systems Behaviour).

In particular, the CROCUS reactor is available for teaching purposes to EPFL physics and engineering students and to students of the nuclear engineering master’s degree course of ETH Zurich and EPFL. The CARROUSEL experiment is used for internships. The LOTUS neutron source has been out of service for several years. The installation is currently being used for irradiation experiments.
