چکیده
The 250 kW TRIGA Mark II research reactor of the Jožef Stefan Institute (JSI) has been in operation since 1966. The reactor went critical on 30 May 1966. It is a light water reactor, with solid fuel elements in which the zirconium hydride moderator is homogeneously distributed between enriched uranium. The reactor core consists of about 70 fuel elements, which are arranged in an annular lattice. A 40 position rotary specimen rack around the fuel elements, two pneumatic transfer rabbit systems, as well as a central thimble and three extra positions in the core are used for irradiation of samples. Other experimental facilities include two radial and two tangential beam tubes, a graphite thermal column and a thermalising column. In 1991 the reactor was almost completely reconstructed with new grid plates, control mechanisms and a control unit and modification of the spent fuel storage pool, among other improvements. The reconstruction additionally involved the installation of a pulse rod, so it can be operated also in a pulse mode. After the reconstruction, the core was loaded with fresh 20% enriched fuel elements, and in 1999 all spent fuel elements were shipped to the USA.

Utilization and Application of the Slovenian Triga Reactor
The Slovenian 250 kW TRIGA Mark II reactor operated by the Jožef Stefan Institute (JSI) has continuously operated since 1966. Since its commissioning it has played an important role in developing nuclear technology and safety culture in Slovenia. During the years the reactor has been utilized for training, research and isotope production. Education and training activities comprise regular exper...
متن کاملIn-situ gamma spectrometry measurements of time-dependent Xenon-135 inventory in the TRIGA Mark II reactor Vienna
In this work, it has been shown that the time dependent Xe inventory in the TRIGA Mark II reactor in Vienna, Austria can be measured via gamma spectrometry even in the presence of strong background radiation. It is focussing on the measurement of (but not limited to) the nuclide Xe. The time dependent Xe inventory of the TRIGA Mark II reactor Vienna has been measured using a temporary beam line...

This paper presents an algorithm for numerical simulations of nonsteady states of the TRIGA MARK II reactor in Vienna, Austria. The primary focus of this work has been the development of an algorithm which provides time series of integral neutron flux after reactivity changes introduced by perturbations without the usage of thermal-hydraulic / neutronic numerical code systems for the TRIGA reac...
متن کاملNeutronics Analysis of the TRIGA Vienna Mixed Core
The 250 kW TRIGA Mark II research reactor, Vienna, operates since 7 March 1962. The initial criticality was achieved with the first core loading of 57 fuel elements (FE) of same type (Aluminium clad fuel with 20% enrichment). Later on due to fuel consumption SST clad 20% enriched FE (s) have been added to compensate the reactor core burn-up. In 1975 high enriched (HEU) TRIGA fuel (FLIP fuel = F...
