The NES research division encompasses the following laboratories:

Laboratory for Reactor Physics and Thermal-Hydraulics (LRT)

Ferroukhi.jpg The LRT is engaged in R&D aimed at an improved understanding of the complex phenomenology of nuclear safety. For current and future nuclear power plants, LRT performs both analytical and experimental research for reactor safety during normal operation up to severe accident conditions as well as for the safety of spent fuel management systems.

Hot Laboratory (AHL)

Laboratory for Waste Management (LES)

Churakov.jpg LES is the Swiss competence center for geochemistry and multi scale radionuclide and mass transport in argillaceous rocks and cement and their applications to deep geological systems and Swiss radioactive waste repositories.

Laboratory for Energy Systems Analysis (LEA)

Dang.jpg The Laboratory aims to contribute to effective decision-making on medium- to long-term technology strategies in energy supply and demand, ensuring integration of major environmental, economic and social factors.
LEA also develops methodologies and carries out the associated risk analyses, probabilistic safety assessment (PSA) and human reliability analysis (HRA) for nuclear power plants as well as other domains. LEA has a mandate to analyze and communicate to decision-makers and stakeholders strengths and weaknesses of energy technologies and broad implications of alternative energy supply strategies.

Laboratory for Nuclear Materials (LNM)

It provides material-related academic R&D contributions and scientific services to the sustainability of current and future nuclear installations for electricity and heat generation or waste reduction as well as to the performance of nuclear research facilities. A special emphasis is placed to the safety and safe long-term operation of the Swiss nuclear power plants, where material-related topics like material ageing play a key role.

Laboratory for Radiochemistry (LRC)

Eichler.jpg The LRC focuses on fundamental research and on education in the field of radiochemistry. The topics studied within LRC cover a wide and diverse range of radiochemical research, including studies on the chemistry of heavy elements, harvesting exotic radionuclides from irradiated accelerator components for use in fundamental research, development of innovative radiopharmaceuticals and studying the chemical behaviour of radionuclides in liquid metals proposed as target material or coolant in future nuclear facilities.

Laboratory for Scientific Computing and Modelling (LSM)
