Great workshop👍👍👍
With insights from R. J. Hawryluk and @ScottCHsu
The big picture looks like this Image
Although we still have a lot of work to do Image
PPP will have a great impact in the future Image
@ENERGY plans to spend $50 M on #FysionEnergy development Image
US realized high competition with @UKAEAofficial Image
Image
What about costs? ImageImage
“As the technology continues to mature, there will be a point where private investors feel that they must be invested in fusion, and I feel like we’re starting to reach that inflection point,” 
@ScottCHsu

That 2021 surge may be a precursor for investments to come if mainstream investors decide to jump into fusion
UK leads public spending on #FusionEnergy and the recent surge in investment came from investors around the globe, but according to @ScottCHsu, about 80% of it went to U.S. companies🙀🙀🙀

Let's go through a brief summary of the

Foresight study on the worldwide developments in advancing #FusionEnergy, including the small scale private initiatives
This study provides an analysis of the leading public and private fusion initiatives globally which has been used to generate 4 foresight scenarios for fusion development Image
The study provides a picture of the most common challenges and barriers to fusion development as well Image

I've got the great one from @unitusviterbo and @renfusion (stellarator approach):
An optimized power conversion system for a stellarator-based nuclear fusion power plant
#FusionEnergy @martinkupp @formbar
The most critical aspect of tokamak power plants is their pulsed duty cycle, which includes long plasma-burn phases followed by fast dwells to remove ashes and dusts from the reactor chamber and re-load the central solenoid
Stellarators with blankets utilizing Pb-17Li as breeder and coolant can reach a maximum operating temperature of 1100 °C
This allows to reach a high power conversion efficiency, due to possible coupling with a Brayton–Rankine Combined Cycle (CC) Image

#ThursdayMoney 🧵

This week we got deep analysis of possible #FusionEnergy cost valuation with @JesseJenkins in the authors' list!🙀🙀🙀
While it is difficult to determine cost of a particular design when much of underlying fusion technology has yet to be developed, it is possible to set cost targets by determining the value of a design with a particular set of operational parameters in a simulated future scenario
This is the first study of the equilibrium value of fusion at various levels of capacity penetration for the United States, and the first investigation of the value of integrated thermal storage for fusion plants in an hourly model

#Backtoschool

Let's talk about fundamentals of #FusionEnergy: plasma energy balance and Lawson criterion
Plasma energy balance is determined by the energy sources feeding the plasma and the energy losses cooling it down

For the plasma to remain stationary, the energy balance must be in equilibrium, i.e. the sources must compensate the losses
The total power produced by the D-T fusion reaction Pfusion is divided between the products of the reaction, the alpha particles, i.e. the helium nuclei (He), and the neutrons

Exascale supercomputers are exactly what current fusion research needs, explains Dr. Choongseok “CS” Chang, lead PI of multi-institutional multi-disciplinary U.S. SciDAC Partnership Center for High-fidelity Boundary Plasma Simulation, headquartered at @PPPLab
One of the biggest current challenges is making accurate predictions about the processes that occur inside tokamak reactors, which use giant magnetic fields to confine plasma fuel in a torus shape to achieve the conditions necessary for fusion
To advance this science, Chang’s team is preparing to use the Aurora Exascale supercomputer, the country’s first Intel-architecture-based exascale HPC system that will be deployed at the U.S. Department of Energy’s (DOE) Argonne National Laboratory

Radiative pulsed L-mode operation in ARC-class reactors - fresh one from @CFS_energy and @MIT_Fusion Image
Enhanced confinement & internal transport barriers create large pressure gradients providing significant bootstrap current fractions. High confinement time allows minimization of plasma current improving stability while also reducing external current drive requirements needed
Recently, high temperature superconductor (HTS) technology has dramatically increased achievable on-axis magnetic field in reactor designs. Since fusion power density scales, this technological advancement provides opportunities to improve self-consistent reactor scenarios
