The research of the division of Nuclear Engineering covers a wide field of topics, both theoretical and experimental.
Stochastic modeling, core analysis, advanced signal analysis, and inverse problem solution is used for problems in reactor diagnosis and noise analysis in nuclear power plants. The same methods are also used and developed for biological and medical signals, e.g. EKG. For future reactor systems, such as Accelerator Driven System, and for safe guard we work with stochastic theory of neutron transport and corresponding coincidence and correlation measurements. We develop and apply transport theory calculations on electron- and positron back scattering from surfaces, and transmission and emission of electrons.

In the area of nuclear technology we have many different projects, e.g. development of coupled neutronic/thermohydraulic tools for noise analysis in nuclear reactors, analysis of Design-Basis Accidents and severe accidents related to the planned power uprates in Sweden, analysis and modeling of phenomena related to the stability of boiling water reactors, and development of efficient coupling schemes between neutron kinetic codes, system codes, and Computational Fluid Dynamics codes

The research activity in fusion plasma physics is directed towards the study of transport and stability of magnetically confined plasmas with a special focus on issues that are relevant for reactor-scale fusion devices. The main focus is to understand how impurities and neutral particles influence plasma behaviour; and what waves are destabilised by fast particles and how can we use this information for plasma control or diagnostics.

Transport of particles and heavy ions in different materials are studied by analysis of measured data and development of transport models and codes. The main goals for these studies are risk assessments and improvement of the radiation shielding for personnel at high altitude flights and space missions outside the earth magnetosphere. Improvement of heavy ion radiation therapy and analysis of the risks involved is another main interest. We are also involved in the development of detector systems for the nuclear power industry.

For our experimental research, we have at our disposal a portable neutron generator, neutron sources, a pulsed positron beam, and detectors. Neutron experiments can be performed in our shielded lab, and the positron beam has its own lab. The pulsed positron beam is under continuous development and is used for positron lifetime spectroscopy. We also perform neutron experiments with, mainly, 14 MeV neutrons.
