Unknown-length motif discovery methods in environmental monitoring time series

Lisa PoiriernHerbeck, Elisabeth Lahalle, N. Saurel, Sylvie Marcos

The search for information of interest in massive time series is crucial in many industrial applications. Companies need their data to be analyzed or modeled in real time, which often requires to extract some patterns, also referred as motifs. However, for diverse …

Bayesian Approach for Multigamma Radionuclide Quantification Applied on Weakly Attenuating Nuclear Waste Drums

Aloïs Clément, N. Saurel, Guillaume Perrin, N. Gombert

Gamma spectrometry is a passive nondestructive assay method used to quantify radionuclides present in nuclear objects. Basic methods using empirical calibration with a standard to quantify the activity of nuclear materials by determining the calibration coefficient are ineffective on nonreproducible nuclear objects …

Stochastic approach for radionuclides quantification

Aloïs Clément, N. Saurel, Guillaume Perrin

Gamma spectrometry is a passive non-destructive assay used to quantify radionuclides present in more or less complex objects. Basic methods using empirical calibration with a standard in order to quantify the activity of nuclear materials by determining the calibration coefficient are useless …

Passive Neutron Coincidence Counting With Plastic Scintillators for the Characterization of Radioactive Waste Drums

B. Simony, Bertrand Pérot, C. Carasco, Fanny Jallu et autres

This paper reports a feasibility study, performed by numerical simulation with MCNPX-PoliMi v2.0, for plutonium quantitative assessment in radioactive waste packages by passive neutron coincidence counting with plastic scintillators. Owing to their low cost and good detection efficiency for fast neutrons, plastic …

Cross-Talk Characterization in Passive Neutron Coincidence Counting of Radioactive Waste Drums With Plastic Scintillators

B. Simony, Clément Deyglun, Bertrand Pérot, C. Carasco et autres

This paper reports on a numerical feasibility study of a passive neutron coincidence counting system for radioactive waste drums with plastic scintillators. The motivation is to replace3He gas counters generally used for this type of measurement. Indeed, plastic scintillators present several advantages …
