TOWARDS THE VALIDATION OF NOISE EXPERIMENTS IN THE CROCUS REACTOR USING THE TRIPOLI-4 MONTE CARLO CODE IN ANALOG MODE [PDF]
EPJ Web of Conferences, 2021 Intrinsic neutron noise experiments offer a non-invasive manner to measure the prompt decay constant or reactivity of fissile systems. Using the fluctuations in the density of fission chains, one can infer the kinetics parameters via correlation analysis

Ultra-thin 3D silicon sensors for neutron detection [PDF]
, 2012 We present a novel neutron detector based on an ultra-thin 3D silicon sensor with a sensitive volume only 10 µm thick. This ultra-thin active volume allows a high gamma-ray rejection, a key requirement in order to discriminate the signal coming from the ...

Nuclear Engineering and TechnologyDuring fast neutron imaging, besides the dark current noise and readout noise of the CCD camera, the main noise in fast neutron imaging comes from high-energy gamma rays generated by neutron nuclear reactions in and around the experimental setup.

Second order of average current nodal expansion method for the neutron noise simulation
Nuclear Engineering and Technology, 2021 The aim of this work is to prepare a neutron noise calculator based on the second order of average current nodal expansion method (ACNEM). Generally, nodal methods have the ability to fulfill the neutronic analysis with adequate precision using coarse ...

Convergence of Monte Carlo methods for neutron noise [PDF]
EPJ Web of ConferencesThe neutron noise δφ describes the small variations of the neutron flux around the stationary state φ0, and is typically due to vibrations or oscillations of the core components, induced by fluid-structure interactions and other generally unwanted ...

SPN Neutron Noise Calculations
, 2021 [EN] Nowadays, non-invasive detection of anomalies in nuclear power plants is possible through neutron noise monitoring. The early detection of such anomalies gives the possibility to take proper actions before they lead to safety concerns or impact on ...
