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

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 ...

Electromagnetic field nonuniformities in large area, high-frequency capacitive plasma reactors, including electrode asymmetry effects

Christoph Hollenstein, Alan Howling, Laurent Fabien Hubert Sansonnens

Electromagnetic wave propagation effects can give rise to important limitations for processing uniformity in large area, radio-frequency (rf) capacitive plasma reactors. The electromagnetic wavefield solution is derived for a capacitive, high-frequency, cy ...

Zero-gain slow and fast light propagation in an optical fiber

Luc Thévenaz, Sang Hoon Chin

Slow and fast light with null amplification or loss of a light signal is experimentally demonstrated. This novel method for producing zero-gain slow and fast light takes advantage of the great flexibility of stimulated Brillouin scattering in optical fiber ...

Proton-triton nuclear reaction in ICRF heated plasmas in JET

Duccio Testa, Christian Schlatter

Fast protons can react with tritons in an endothermic nuclear reaction which can act as a source of neutrons in magnetically confined fusion plasmas. We have performed an experiment to systematically study this reaction in low tritium concentration (approx ...

Comparisons of deterministic neutronic calculations with Monte Carlo results for an advanced BWR fuel assembly with hafnium control blades

Rakesh Chawla, Filippo Tani, Fabian Jatuff, Michaël Plaschy, Flavio Dante Giust

From the neutronic viewpoint, the optimization of BWR core designs is strongly related to the accurate determination of flux variations inside and around fuel assemblies. These fluctuations, which are mainly due to the high heterogeneity of the fuel and mo ...

Determination of adjusted neutron spectra in different MUSE configurations by unfolding techniques

Rakesh Chawla, Michaël Plaschy

Investigations of spectrum adjustment by unfolding techniques for different locations of critical and driven subcritical MUSE4 configurations are presented. The current analysis is based on the recent accomplishment of specific foil activation measurements ...

Petrology and geochemistry of the fine-grained, unbrecciated diogenite Northwest Africa 4215

Philippe Gillet, Pierre Beck

We report on the petrology and geochemistry of Northwest Africa (NWA) 4215, an unbrecciated diogenite recovered in the Sahara. This single stone, weighing 46.4 g, displays a well-preserved cumulative texture. It consists of zoned xenomorphic orthopyroxene ...

A Galileo E1b,c RF Front-End Optimized for Narrowband Interferers Mitigation

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain, Davide Manetti, Giuseppe Zamuner

The current Search and Rescue (SAR) service, which is based on the Cospas-Sarsat system, suffers from major limitations such as poor position accuracy, long alert times and high false alarm rate. Two types of distress signals are used, the first 121.5MHz/( ...

FAST: An advanced code system for fast reactor transient analysis

Rakesh Chawla, Konstantin Mikityuk

One of the main goals of the FAST project at PSI is to establish a unique analytical code capability for the core and safety analysis of advanced critical (and sub-critical) fast-spectrum systems for a wide range of different coolants. Both static and tran ...

Importance of the MUSE experiments for emerging ADS concepts from the nuclear data viewpoint

Rakesh Chawla, Michaël Plaschy, Gérald Rimpault

The current investigation, conducted in the general framework of the MUSE program ("MUltiplication avec une Source Externe"), considers the representativity of a specific configuration of its fourth phase (M4SC2), which is driven by an external D(d,n)He3 o ...
