Neutronic Analysis of SiC/SiC Sandwich Cladding Design in APR-1400 under Normal Operation Conditions

Energies, 2022
Our aim is to study the neutronic behaviour of potential accident-tolerant fuel (ATF) claddings in a pressurised water reactor under normal operations. This work compares ATF silicon carbide composite (SiC/SiC) cladding to conventional ZIRLOTM cladding ...

One-dimension model for transport of organic contaminants in double-artificial composite liner under thermal osmosis

Yantu gongcheng xuebao
A one-dimensional model for transport of organic contaminants in a double-artificial composite liner under thermal osmosis is proposed. The model is simulated by using the COMSOL Multiphysics. The results show that the bottom concentration only increases

SDSS-IV MaNGA: Identification of active galactic nuclei in optical integral field unit surveys [PDF]

, 2017
In this paper, we investigate 2727 galaxies observed by MaNGA as of June 2016 to develop spatially resolved techniques for identifying signatures of active galactic nuclei (AGN). We identify 303 AGN candidates.

Issues of steep sideslope liners that remain exposed and are later covered [PDF]

E3S Web of Conferences
The steepness of sideslope bottom liner systems for landfills, heap leach pads, and tailings dams often precludes the safe placement of overliner cover soil at the end of construction. As a result, a composite liner system might remain exposed for months
