Abstract

This paper presents an algorithm for numerical simulations of non-steady\nstates of the TRIGA MARK II reactor in Vienna, Austria.\n The primary focus of this work has been the development of an algorithm which\nprovides time series of integral neutron flux after reactivity changes\nintroduced by perturbations without the usage of thermal-hydraulic / neutronic\nnumerical code systems for the TRIGA reactor in Vienna, Austria. The algorithm\npresented takes into account both external reactivity changes as well as\ninternal reactivity changes caused by feedback mechanisms like effects caused\nby temperature changes of the fuel and poisoning effects. The resulting time\nseries have been compared to experimental results.\n
