TAILIEUCHUNG - Computational burnup analysis of the TRIGA Mark II research reactor fuel

In this study, analysis of the complete operational history of the “Joˇzef Stefan” Institute (JSI) TRIGA reactor was performed. Reactor power changes, core configurations and weekly excess reactivity measurements were analysed to obtain the needed data for fuel burnup calculations. | Progress in Nuclear Energy 130 2020 103536 Contents lists available at ScienceDirect Progress in Nuclear Energy journal homepage http locate pnucene Computational burnup analysis of the TRIGA Mark II research reactor fuel Anˇze Pungerˇciˇc a b Duˇsan Cali ˇ ˇc a Luka Snoj a b a Reactor Physics Department Joˇzef Stefan Institute Jamova cesta 39 1000 Ljubljana Slovenia b Faculty of Mathematics and Physics University of Ljubljana Jadranska ulica 19 1000 Ljubljana Slovenia A R T I C L E I N F O A B S T R A C T Keywords In this study analysis of the complete operational history of the Joˇzef Stefan Institute JSI TRIGA reactor was TRIGA research reactor and Fuel Burnup performed. Reactor power changes core configurations and weekly excess reactivity measurements were ana Operational history analysis lysed to obtain the needed data for fuel burnup calculations. More than 50 years of reactor operation was Serpent-2 simulated using deterministic code TRIGLAV and stochastic code Serpent-2. The calculated core reactivities are TRIGLAV Excess reactivity measurements in good agreement compared with the excess reactivity measurements. Code-to-code comparison is presented. Clear agreement is observed when comparing changes in core excess reactivity and discrepancies are observed in the comparison of individual fuel element burnup and its isotopic composition. The Serpent-2 results are in better agreement with the measurements compared to the TRIGLAV code nevertheless a conclusion can be made that the TRIGLAV code is viable for TRIGA fuel management and burnup analysis. A three-dimensional 3D burnup study was conducted where individual fuel elements were further divided into multiple angular and axial depletion zones. Notable burnup effects were observed and an explanation using surrounding water distance is presented. 1. Introduction isotopes using modern tools which enable 3D Monte Carlo burnup calculations using detailed operational data. Our goal was to .
