Atomic level insight into irradiation effects in nuclear fuel materials
Microstructural evolution during in-pile irradiation, radiation damage effects and fission products behavior in UO2 nuclear fuel are key issues in understanding and for the modeling of the performance as well as safety characteristics of nuclear fuels in t ...
EPFL2024Validation of spent nuclear fuel decay heat calculations using Polaris, ORIGEN and CASMO5
Andreas Pautz, Dimitri Rochman, Stefano Caruso
Decay heat calculations of spent nuclear fuel (SNF) using Polaris and ORIGEN codes in the SCALE code sys-tem, and CASMO5 code, are validated using measurements from the Clab and GE-Morris facilities. Multiple hypothesis testing, relying on permutations and ...
PERGAMON-ELSEVIER SCIENCE LTD2022Data-Driven Predictive Models: Calculational Bias in Characterization of Spent Nuclear Fuel
Characteristics of the spent nuclear fuel (SNF) are typically calculated, requiring validation a priori. The validation process relies on the difference between calculations and measurements, namely the bias. Usually, predicting the bias based on benchmark ...
EPFL2022Structural performance and mechanical properties investigation of spent nuclear fuel rods under static and dynamic bending loads
Currently, most Spent Nuclear Fuel (SNF) is kept safely in storage either at on-site facilities or at centralized interim storage sites. Moreover, many countries face delays in implementing their waste management programmes for SNF and high-level waste dis ...
EPFL2021Uncertainty analyses of spent nuclear fuel decay heat calculations using SCALE modules
Andreas Pautz, Dimitri Rochman, Stefano Caruso
Decay heat residuals of spent nuclear fuel (SNF), i.e., the differences between calculations and measurements, were obtained previously for various spent fuel assemblies (SFA) using the Polaris module of the SCALE code system. In this paper, we compare dec ...
KOREAN NUCLEAR SOC2021Optimisation of used nuclear fuel canister loading using a neural network and genetic algorithm
Andreas Pautz, Hakim Ferroukhi, Dimitri Rochman, Alexander Vasiliev
This paper presents an approach for the optimisation of geological disposal canister loadings, combining high resolution simulations of used nuclear fuel characteristics with an articial neural network and a genetic algorithm. The used nuclear fuels (produ ...
SPRINGER LONDON LTD2021Growth and viability of microorganisms in bentonite and their potential activity in deep geological repository environments
Radioactive waste is among the most dangerous anthropogenic waste and its safe disposal is a challenging multi-generational task. Many nations have sought for the peaceful application of nuclear fission for the reliable production of electric energy to pow ...
EPFL2021Loading optimization for Swiss used nuclear fuel assemblies into final disposal canisters
Andreas Pautz, Hakim Ferroukhi, Dimitri Rochman, Alexander Vasiliev
In this study, an optimization of the canister loading for used nuclear fuels is performed, solely based on their decay heat values. By taking into account the individual irradiation history for each fuel assembly, as well as with a number of assumptions o ...
ELSEVIER SCIENCE SA2020Increasing understanding and confidence in THM simulations of Engineered Barrier Systems.
Lyesse Laloui, Alessio Ferrari, Yafei Qiao
Previous studies on the modelling of coupled thermo-hydro-mechanical (THM) processes in bentonite-based engineered barrier systems (EBSs) showed the sensitivity of the output quantities to changes in the input parameters. To investigate the effects of unce ...
2019High-Fidelity Determination of Nuclide Inventories for Radioactive Waste Disposal
The general license application (RBG) for the Swiss deep geological repository will be submitted in 2024. Furthermore, the decommissioning of the nuclear power plants (NPPs) is coming soon, with the Mühleberg NPP (KKM) scheduled to shut down in 2019. In su ...
