Heat pipe technology based divertor plasma facing component concept for European DEMO

Fully Fresh Air Air-conditioning System Equipped with Double Heat Pipe Based Heat Recovery Technology

The using of double heat pipe based heat exchanger (HPHX) in a conventional fully fresh air air-conditioning (AC) system was examined in the present study. The fabricated HPHXs were tested under the actual conditions and the measured data were used to study the performance of the existing AC system (System A) and AC system equipped with the double HPHX (System B) for a yearly operation through ...

Numerical Simulation Analysis for the Divertor Plate of DEMO Reactor

The hydraulic simulation and structure coupled analysis were used to explore critical heat flux (CHF) margin of the W (tungsten) armour and the accommodation of the thermal stress between the cooling tube and the W armour. The t (wall thickness of the F82H tube) variation or as a constant were considered to analysis the heat removal capability of the cooling tube. It was found a nonlinear distr...

Potential of Heat Pipe Technology in Nuclear Seawater Desalination

A Titanium Based Flat Heat Pipe

1. ABSTRACT We are developing innovative heat pipes based on Nano-Structured Titania (NST) with a potential for high heat carrying capacity and high thermal conductivity. These heat pipes have a flat geometry as opposed to a cylindrical geometry found in conventional heat pipes. The flatness will enable a good contact with microprocessor chips and thus reduce the thermal contact resistance. We ...

ARIES-ST plasma-facing component design and analysis

ARIES-ST is a 1000 MW fusion power plant conceptual design based on a low aspect ratio ‘spherical torus’ (ST) plasma. The plasma-facing components include the inboard and outboard first wall, divertor plates, and plasma stability plates. Several unique aspects of ST plasma influence the engineering design. The limited inboard space precludes a full inboard divertor slot, such that substantial p...
