About LRS

The LRS as a laboratory of the Energy and Safety Division (NES) of the Paul Scherrer Institut (PSI) is engaged in both analytical and experimental R&D related to the operation of current and future nuclear power plants. Its strategic goal is to strengthen the sustainability of nuclear power via research along the following two principal lines
  • Improved understanding of the complex phenomenology of nuclear safety,
  • Physics of complete fuel cycle closure in the context of plutonium management and waste reduction.
Thereby, the use of large facilities of PSI, such as the Hot Labor and the SINQ has played a central role in LRS up until now. In addition, the laboratory is, since several years, actively involved in international collaboration on experimental reactor physics. This allows compensating for the decommissioning of the PROTEUS facility, decided in 2011, by carrying out experiments in foreign research reactors (e.g. EOLE in CEA Cadarache and BR1 in SCK.CEN),

Furthermore, the lab’s activities have a direct bearing on education in nuclear science and technology (fission) at the Ecole Polytechnique Fédérale de Lausanne (EPFL), the LRS projects largely determining the framework for both PhD and Master’s research topics at EPFL in this field. LRS plays a key role in the joint program by EPFL and ETH Zurich offering a Master of Science (MSc) in Nuclear Engineering.
