Data-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 ...
EPFL2022Studies on the mechanical evolution of compacted bentonite subjected to environmental actions
Deep geological disposal is currently the most feasible option for the long-term isolation of radioactive waste, consisting in emplacing the waste into tunnels or drifts excavated at great depths in suitable geological formations. The use of bentonite, a h ...
EPFL2021The Fukushima Inverse Problem
Martin Vetterli, Ivan Dokmanic, Juri Ranieri, Robin Scheibler, Marta Martinez-Camara
Knowing what amount of radioactive material was released from Fukushima in March 2011 and at what time instants is crucial to assess the risk, the pollution, and to understand the scope of the consequences. Moreover, it could be used in forward simulations ...
2013From Becquerel To Nanotechnology: One Century Of Decline Of Scientific Dissemination, Publishing And Technology Transfer
2008 marks the 100th anniversary of Henri Becquerel's death, the discoverer of radioactivity and a leading contributor to the birth of modern physics. In addition to well-deserved celebrations, this offers a chance for a sobering look at scientific dissemi ...
World Scientific Publishing2010Experimental validation of radial reconstructed pin-power distributions in full-scale BWR fuel assemblies with and without control blade
Rakesh Chawla, Flavio Dante Giust
Total fission rate measurements have been performed on full-size BWR fuel assemblies of type SVEA-96+ in the zero power reactor PROTEUS at the Paul Scherrer Institute. This paper presents comparisons of reconstructed 2D pin fission rates from nodal diffusi ...
Elsevier2010Analysis of labelled compounds by mass spectroscopy in the presence of heavy isotopes at natural abundance: the NAIC program
A program is described, which allows the intensity contributions from naturally occurring heavy isotopes to be eliminated from the mass spectrometric ions of an artificially labelled compound. This allows the accurate measurement of the isotopomer distribu ...
2009Radiation shielding of a beta-beam rapid cycling synchrotron
In a future beta-beam facility, radioactive ions (namely, 6He and 18Ne) are produced, accelerated, and then stored in a large decay ring, where they eventually produce neutrino beams through beta decay. Radiation protection is of great concern for this fac ...
American Nuclear Society2009Analysis of radioactivity releases in the MEGAPIE reference accident
A computer model for the MEGAwatt Pilot Target Experiment (MEGAPIE) was developed, verified and applied to the analysis of the reference accident, resulting from the hypothetical loss of a Pb–Bi inventory and subsequent cooling down of the target with free ...
2008Overview of transport, fast particle and heating and current drive physics using tritium in JET plasmas
Results are presented from the JET Trace Tritium Experimental (TTE) campaign using minority tritium (T) plasmas (n(T)/n(D) < 3%). Thermal tritium particle transport coefficients (D-T, nu(T)) are found to exceed neo-classical values in all regimes, except i ...
2005Structural materials for fusion reactors
In order to preserve the conditions for an environmentally safe machine, at present the selection of materials fur the structural components of fusion reactors is made not only on the basis of adequate mechanical properties, behaviour under irradiation, an ...
