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

Great workshopđź‘Ťđź‘Ťđź‘Ť
With insights from R. J. Hawryluk and @ScottCHsu
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
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
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

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
Radiative pulsed L-mode operation in ARC-class reactors - fresh one from @CFS_energy and @MIT_Fusion
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

Right now, the tritium used in fusion experiments like @iterorg, and the smaller JET tokamak in the UK, comes from a very specific type of nuclear fission reactor called a heavy-water moderated reactor
