Delocalized organic pollutant destruction through a self-sustaining supercritical water oxidation process
Elena Daniela Lavric,Elena Daniela Lavric,H. Weyten,J. De Ruyck,Valentin Plesu,Vasile Lavric +5 more
TL;DR: In this article, the process of supercritical water oxidation (SCWO) for dilute waste water (no more than 5wt.%) is modelled through the ASPEN Plus © process simulator, and the results obtained showed that the process is energetically self-sufficient using either a small supercritical turbine, or an ORC.

Revolutionizing heat transport enhancement with liquid metals: Proposal of a new industry of water-free heat exchangers
Haiyan Li,Jing Liu,Jing Liu +2 more
TL;DR: In this paper, the concept of a water-free heat exchanger is proposed and comprehensively analyzed for the first time, and comparative analyses are conducted to understand the technical barriers encountered by advanced water-based heat transfer strategies and clarify this new frontier in heat-transport study.

Fusion energy conversion in magnetically confined plasma reactors
TL;DR: In this paper, the energy conversion in magnetically confined plasma reactors is addressed and the chamber wall surrounding the plasma is built from the plasma facing components and from the blanket and divertor modules where the fusion energy is converted into the thermal energy, tritium is produced, and the external components of the chamber are shielded from radiation.

Development of high thermal flux components for continuous operation in tokamaks
TL;DR: High-heat-flux candidate structures of square-shaped dispersion-strengthened copper tubes with heat-transfer-enhanced swirl tape inserted into the cooling channel have been successfully tested in the CEA-FRAMATOME EB (electron beam) facility and in the NB (neutral beam) test bed at JET (Joint European Torus) as discussed by the authors.
