Reactor Physics Department (F8) Home Page


Department research in reactor physics is oriented mostly into new methods for power and research reactor calculations, where special attention is given to the calibration and benchmarking of nuclear data  and computational methods. Complete power reactor core design package has been developed by Department's researchers. This core design package is being used to calculate fuel cycles for Krsko Nuclear Power Plant since its initial startup. New “Rod Insertion” method for control cluster worth measurement and relevant measuring equipment, which enables significant reduction of time needed for post-refuelling startup tests of a nuclear power plant was developed at our department. Code packages and methods for research reactors, like our Ljubljana TRIGA reactor were developed. We also perform  neutron transport calculations for JET – Joint European Torus.
The main research area in Plasma physics laboratory is development of plasma diagnostics inside fusion devices.
Our research in the field of medical physics is directed towards the image-guided cancer therapy.
Semiconductor physics research is mostly oriented towards better understanding of metal – semiconductor junction and development of organic semiconductors.

Film about department in the year 2020 by Jan Malec.




From 28th September to 2nd October, 2020 was organized Dedicated Practical Educational Course ‘’Experimental reactor physics’’ for students from Uppsala University at JSI TRIGA reactor. Course was first time, because of the covid-19 organized  remotely.

During the two-week invited visit at the University of Ljubljana, Faculty of Mathematics and Physics, Dr. Alireza Haghighat from Virginia Tech had the course at Reactor center of the Jozef Stefan Institute, Ljubljana.
For more information, you can see the agenda for the course "Particle Transport Methods and Application".
During his visit, discussions were held on further cooperation between Virginia Tech and JSI.

From 26th to 30th March, 2018 was organized MIT Dedicated Practical Educational Course "Experimental reactor physics" at TRIGA reactor.
