English abstract:
The TRIGA reactor Vienna operates since March 1962 at the rather low power of 250 kW and with a completely mixed core using two types of LEU and one type of HEU elemts since 1974. This makes a detailed core calculation difficult especially as many relevant data for MNCP calculation were not always readily available. Further there are only very fwe TRIGA reactors with such a core composition. In the absence of good burn up and temperature data for the core a parametric study with all fresh fuel and averaged fuel temperature for different fuel element mixes was done. This includes thermal/fast flux, hot rod factor and keff estimation for an all 102, a 102/104 mixed and a 102/104/FLIP mixed core. The model was run using MCNP 5.14 together with the ENDF/B-VI.5 library.
