Thorium and fetal neural tube defects: an epidemiological evidence from large case-control study

Genes and Environment, 2021
Background Thorium is ubiquitous in the environment and its relationship with birth defects is still under discussion. This study aimed to investigate the associations of maternal exposure to thorium with risk of neural tube defects (NTDs) by using a ...

Thermal transport in thorium dioxide

Nuclear Engineering and Technology, 2018
In this research paper, the thermal transport in thorium dioxide is investigated by using nonequilibrium molecular dynamics. The thermal conductivity of bulk thorium dioxide was measured to be 20.8 W/m-K, confirming reported values, and the phonon mean ...

The influence of lattice defects, recombination, and clustering on thermal transport in single crystal thorium dioxide

, 2020
Thermal transport is a key performance metric for thorium dioxide in many applications where defect-generating radiation fields are present. An understanding of the effect of nanoscale lattice defects on thermal transport in this material is currently ...

Extension of the formula between reactivity and concentrations of fissile and non-fissile nuclide in the fuel salt for thermal neutron spectrum molten salt reactors

Nuclear Engineering and Technology
Due to the unique properties of liquid fuel in molten salt reactors (MSRs), reactor reactivity is directly correlated with the fuel salt composition. Previous studies have established and verified a linear relationship between reactivity and the inverse ...
