The NES research division encompasses the following laboratories:

Laboratory for Reactor Physics and Systems Behaviour (LRS)

Ferroukhi.jpg The LRS is engaged in R&D related to the operation of current and future nuclear power plants. Its strategic goal is to strengthen the sustainability of nuclear power. This requires an improved understanding of the complex phenomenology of nuclear safety. Physics of complete fuel cycle closure in the context of plutonium management and waste reduction.

Laboratory for Thermal-Hydraulics (LTH)

Prasser.jpg The LTH is engaged in both analytical and experimental research and development (R&D) related to the design basis (DBA), beyond design basis (BDA) and severe accident (SA) conditions of current and future nuclear power plants.

Hot Laboratory Division (AHL)

Streit.jpg The AHL is the only Swiss laboratory authorized by the safety authorities to handle large quantities of radioactive materials including commercial as well as experimental nuclear fuel.

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)

Pouchon.jpg The LNM is the principal research unit and national centre of excellence in Switzerland in the domains of (radioactive) materials behaviour and ageing in nuclear installations. 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)

Tuerler.jpg The LRC focuses on fundamental research and on education in the field of radiochemistry. The Laboratory is a joint activity of the PSI and the University of Bern. The five research groups explore the chemistry of heavy elements, study the radionuclide inventory in beam targets of large scale irradiation facilities, provide novel radionuclides for future medical applications, and develop measurement techniques of environmental radionuclides in geoscientific research.
