Preliminary safety analysis of the TRANSMUTEX sub-critical reactor using the GeN-Foam multi-physics solver

Andreas Pautz, Carlo Fiorina, Thomas Arthur Louis Joseph Guilbaud

This work presents a preliminary safety analysis of the accelerator-driven system under development at TRANSMUTEX. It is a sub-critical lead-cooled fast reactor with a nominal power of 300 MWth having the following features: (1) an inert-matrix fuel; (2) a ...

Progress in modelling solidification microstructures in metals and alloys: dendrites and cells from 1700 to 2000

Wilfried Kurz

This is the first account of the history of our understanding of, and ability to model, solidification microstructures. Its objective is to retrace the scientific steps made, from the earliest observations of the eighteenth century to our present-day under ...

Textured BaTiO3 by templated grain growth and electrophoretic deposition

Dragan Damjanovic

[001]-Oriented barium titanate (BaTiO3) ceramics were prepared by templated grain growth using [001]-oriented plate-like template BaTiO3 particles, synthesized via the molten salt method. Platelets synthesized in a 2-step or 3-step molten salt were used in ...

Coupled 3-D Neutronics/Thermal-Hydraulics Optimization Study For Improving The Response Of A 3600 Mw(Thermal) Sfr Core To An Unprotected Loss-Of-Flow Accident

Rakesh Chawla, Aurélia Chenu, Konstantin Mikityuk, Jiri Krepel, Kaichao Sun

The sodium-cooled fast reactor (SFR), as a fast neutron spectrum system, is characterized by several performance advantages. In particular, the long-term operation of an SFR core in a closed fuel cycle will lead to an equilibrium state, where both reactivi ...

Investigation of liquid LBE embrittlement effects on irradiated ferritic/martensitic steels by slow-strain-rate tensile tests

Nadine Baluc, Yong Dai

In the present work, LBE (lead-bismuth eutectic) embrittlement effects on ferritic/martensitic (FM) steels have been studied by conducting slow-strain-rate tensile (SSRT) testing on T91 and F82H steels either in Ar or in liquid LBE after irradiation to dos ...

Post-irradiation analysis of the tantalum container of an ISOLDE LBE target

CERN-ISOLDE operates a range of oxides, carbides, refractory metal foils and liquid metal targets for the production of radioactive ion beams. Following irradiation with a pulsed beam of 1 GeV and 1.4 GeV protons at temperatures reaching 600 degrees C, the ...

Energy-Efficient Variable-Flow Liquid Cooling in 3D Stacked Architectures

David Atienza Alonso, Ayse Kivilcim Coskun, Bruno Michel

Liquid cooling has emerged as a promising solution for addressing the elevated temperatures in 3D stacked architectures. In this work, we first propose a framework for detailed thermal modeling of the microchannels embedded between the tiers of the 3D syst ...

Liquid lead-bismuth embrittlement effects on unirradiated and irradiated ferritic/martensitic steels for nuclear applications

Bin Long

In liquid metal spallation targets such as the MEGAPIE (the megawatt pilot experiment) target and the future ADS (accelerator driven system) spallation targets, which utilize liquid lead-bismuth eutectic (LBE) as the target material, liquid metal embrittle ...

Modeling and Dynamic Management of 3D Multicore Systems with Liquid Cooling

David Atienza Alonso, José Luis Ayala Rodrigo, Ayse Kivilcim Coskun

Three-dimensional (3D) circuits reduce communication delay in multicore SoCs, and enable efficient integration of cores, memories, sensors, and RF devices. However, vertical integration of layers exacerbates the reliability and thermal problems, and coolin ...

Comparison of the transient behaviour of LBE-and gas-cooled experimental accelerator-driven systems

Rakesh Chawla, Konstantin Mikityuk

The paper presents a comparison of transient calculations for two 80-MWt MOX-fuelled experimental accelerator-driven systems (XADS), one cooled by lead-bismuth eutectic and the other by helium. The results for protected (with accelerator beam trip) and unp ...
