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 ...

Optimisation 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 ...

Investigation on the effect of eccentricity for fuel disc irradiation tests

Andreas Pautz, Carlo Fiorina, Alessandro Scolaro

A varying degree of eccentricity always exists in the initial configuration of a nuclear fuel rod. Its impact on traditional LWR fuel is limited as the radial gap closes relatively early during irradiation. However, the effect of misalignment is expected t ...

Load Transfer Method for Energy Piles in a Group with Pile–Soil–Slab–Pile Interaction

Lyesse Laloui, Elena Ravera, Melis Sütman

The behavior of an energy pile in a group is different from that of an isolated energy pile due to thermal and mechanical interactions. This study aims to extend the load transfer method to consider the mechanical and thermal interactions of energy piles i ...

Load transfer approach for the geotechnical analysis of energy piles in a group with slab

Lyesse Laloui, Elena Ravera, Melis Sütman

Thermally induced group effects characterise closely spaced energy piles. It has been observed experimentally that the behaviour of energy piles subjected to mechanical and thermal loads, in which the piles are located sufficiently close to each other, is ...

Thermal stress analysis of energy piles

Lyesse Laloui, Cristiano Garbellini

This study is concerned with the problem of energy piles subjected to constant axial load and temperature variation uniform over the cross-section. In the first part of this article, equations for the analysis of energy piles based on elastic theory and th ...

Performance-based Design of Energy Pile Foundations

Alessandro Francesco Rotta Loria

Over the past twenty years, an increasing amount of research has been performed to understand the multiphysical behaviour and to address the geotechnical and structural design of so-called energy piles, i.e. deep foundations that can serve any superstructu ...

First Steps Towards The Development Of A 3D Nuclear Fuel Behavior Solver With Openfoam

Andreas Pautz, Carlo Fiorina, Alessandro Scolaro

A new 3D fuel behavior solver is currently under collaborative development at the Laboratory for Reactor Physics and Systems Behaviour of the Ecole Polytechnique Federale de Lausanne and at the Paul Scherrer Institut. The long term objective is to enable a ...

Load-Transfer Approach for Modeling the Cyclic Thermo-Mechanical Behaviour of Energy Piles

Lyesse Laloui, Melis Sütman

Energy piles are subjected to short- and long-term cyclic thermal loads due to their unique role as heat exchangers. Their response to monotonic temperature change has been investigated by various researchers from both experimental and numerical points of ...

Analysis of the vertical displacement of energy pile groups

Lyesse Laloui, Alessandro Francesco Rotta Loria

Over the last fifty years, the interaction factor method has been widely used to address the vertical displacement and the increased deformation of conventional pile groups subjected to mechanical loads when group effects and interactions occur among the p ...
