Centre (RIC) is part of "Jožef Stefan" Institute
(JSI). Main purpose of the centre is operation of TRIGA
reactor for the needs of JSI and other research groups.
TRIGA Mark II is designed for:
Reactor TRIGA Mark II was built by Jožef Stefan Institute in 1966. The reactor was delivered by GA, the reactor tank and body were built by Slovenian companies. In 1991 it was reconstructed and equipped for pulse operation.
The reactor has accu50mulated years of continuous operation without any failure of major equipment or any event violating safety standards.
Technical conditions of the reactor allow for at least 10 years more operation. It is planed that the reactor will operate at least until 2026.
RIC is in organizational sense an infrastructure centre established and financed by the Ministry of Higher Education, Science and Technology and managed by Jožef Stefan Institute, like several other centres responsible for operating and maintaining large research equipment (e.g. accelerators, etc).
RIC is, however, in regulatory sense, a nuclear installation operated by Jožef Stefan Institute. Its operation is regulated by several national and international nuclear laws, regulations and standards.
Their enforcement is regularly controlled by national and international bodies:
Reactor building, reactor site and its surroundings are subject to permanent and systematic radiation monitoring performed by IJS Radiation Protection Group. Results of the monitoring are reported to Slovenian Nuclear Safety Administration and published in their annual report on nuclear and radiological safety.
In 35 years there has been no release of radioactivity into environment (in atmosphere or in water) exceeding limiting values prescribed by the law.
The cornerstones of TRIGA reactor nuclear safety are:
All questions related to nuclear safety are treated in detail in Safety Analysis Report.
generates approximately 50 liters
of low and intermediate radioactive waste per year. It
is stored in the central storage for low and
intermediate level waste located at the location of the
reactor centre and operated by the Agency for
Nuclear Waste (ARAO).
219 spent fuel elements accumulated in operation since 1966 have been shipped for final disposal to USA in 1999. Presently, there are no spent fuel elements (highly radioactive waste) on the location of the Reactor Centre.
Our main achievements
The reactor has been playing important role in developing nuclear technology and safety culture in Slovenia. It is one of a few centres of modern technology in the country. Its international cooperation and reputation are important for promotion of Jožef Stefan Institute, Slovenian science and Slovenia in the world.
Practical benefits can be divided into three categories like the purpose of the reactor: training, research and isotope production.
