Comparison of CFETR nuclear fusion power plant thermal storage technology

He jishu
BackgroundDue to its pollution-free nature and non consumption of fossil fuels, nuclear fusion is the most ideal future energy source. China is preparing to build a China Fusion Engineering Test Reactor (CFETR) with independent intellectual property ...

Mechanisms of Increasing Weld Depth during Temporal Power Modulation in High‐Power Laser Beam Welding

Advanced Engineering Materials, EarlyView.
Temporal power modulation increases weld depth in high‐power laser beam welding of dissimilar round bars by nearly 20% compared to same average continuously welded welding power. The mechanism of action also applies to sheet welding and depends on the inertia of keyhole depth for the modulated laser beam power.

Characterizing fusion market entry via an agent-based power plant fleet model

Energy Strategy Reviews, 2019
An agent based model characterizing the U.S. power plant fleet was formulated to compare scenarios for fusion energy technology diffusion. The model employs historical data to form distributions for power plant retirements, and simulates construction of ...

Doubling fusion power with volumetric optimization in magnetic confinement fusion devices

Physical Review Research
A technique, volumetric power optimization, is presented for enhancing the power output of magnetic confinement fusion devices. Applied to a tokamak, this approach involves shifting the burning plasma region to a larger plasma volume while introducing ...

A Novel Approach to Produce Metal–Metal Composites by Leveraging Immiscibility: Laser Powder Bed Fusion of Nanosilver‐Dispersed Titanium

Advanced Engineering Materials, EarlyView.
Incorporating nanosized silver into titanium for antimicrobial materials exploits the metastable miscibility gap between silver and titanium. Silver nanoparticles are synthesized via pulsed laser ablation in liquid. Silver addition refines the microstructure, increases hardness by 30%, and reduces Staphylococcus capitis microbial adhesion by 70%, with ...

Maillard Type Reaction for Electroless Copper Plating onto Ceramic Nanoparticles

Advanced Engineering Materials, EarlyView.
This work presents the manufacturing of copper‐plated ceramic nanoparticles in an environmentally friendly way. Supported by organic functionalizations with pectin an electroless plating step can be performed. Sustainable reagents like xylose, and several amino acids are used for the reduction process.

Fusion - A Potential Power Source or Not? [PDF]

Journal of Chemical Education, 1996
Natural abundance of deuterium reported in original letter is off by 100 times, and if we use nuclear fusion to replace hydrocarbon combustion it will result in a marked decline in living standards.

Electric Power Enhancement using Spin-Polarized Fuel in Fusion Power Plants [PDF]

arXiv
Using a range of fusion power plant (FPP) concepts, we demonstrate that spin-polarized fuel (SPF) can significantly enhance net electric power output, often by many multiples. Notably, the electric power gain from SPF generally exceeds the corresponding increase in thermal fusion power. Plants close to engineering breakeven stand to benefit most, where

Influence of Cooling Rate on Primary Silicon Size in Hypereutectic Al–Si Alloy Fabricated by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Al–Si alloys are particularly in demand for automotive and electronic applications, thanks to their excellent wear and thermal properties. Nevertheless, when processed by conventional methods with low cooling rates, the coarse primary Si phases are responsible for increasing brittleness and inducing crack propagation.

Cryogenic Engineering and Fusion Power [PDF]

, 1995
The goal of controlled fusion research is to eventually produce electric power; after some twenty years of worldwide research effort, there has been much progress toward this goal. We can now outline a reasonable timetable for the U. S. fusion program which leads to the possibility of commercial power in about thirty years [1]; this assumes that a ...
