Investigation of shielding parameters of some boron containing resources for gamma ray and fast neutron

Results in Physics, 2019
Mass attenuation coefficient (μt) of some boron containing resources in China were investigated in the paper at 0.001–20 MeV through XCOM and Geant4. What’s more, half value thickness layer (HVL), mean free path (MFP), effective atomic number (Zeff) and ...

Fast neutron detection efficiency of 6Li and 7Li enriched CLYC scintillators using an Am-Be source [PDF]

Journal of Instrumentation, 2018
The fast neutrons produced by a calibrated 241Am-Be source were detected by two different Cs2LiYCl6:Ce (CLYC) scintillator detectors. The two cylindrical crystals (1′′× 1′′ in size) were enriched with more than 99% of 7Li (C7LYC) and with about 95% of ...

A high-density gamma white spots-Gaussian mixture noise removal method for neutron images denoising based on Swin Transformer UNet and Monte Carlo calculation

Nuclear Engineering and Technology
During 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.

Core Optimization for Extending the Graphite Irradiation Lifespan in a Small Modular Thorium-Based Molten Salt Reactor

Journal of Nuclear Engineering
The lifespan of core graphite under neutron irradiation in a commercial molten salt reactor (MSR) has an important influence on its economy. Flattening the fast neutron flux (≥0.05 MeV) distribution in the core is the main method to extend the graphite ...
