Reactor Infrastructure Centre

The Reactor Infrastructure Centre (RIC) is a national research infrastructure providing access to the TRIGA Mark II research reactor, the Hot Cells Facility and associated equipment for scientific, educational and industrial purposes. Located in Podgorica near Ljubljana, within the Jožef Stefan Institute, it provides a modern and safe environment for advanced research, testing and training activities. 

60th Anniversary of the TRIGA Reactor

The TRIGA research reactor is celebrating its 60th anniversary of operation this year. On the occasion of the 60th anniversary of the TRIGA research reactor’s operation, the President of the Republic of Slovenia, Dr. Nataša Pirc Musar, will award the Jožef Stefan Institute the Golden Order of Merit for its exceptional contribution to the development of science, research, and education in the field of nuclear technology — an honour of which we are extremely proud.
