Discussion and news on advancements in the field of nuclear fusion energy and related technologies.

Nuclear Fusion on Reddit

Focused on advancements in the field of nuclear fusion.

Submissions should be related to nuclear fusion or plasma physics as currently understood by the scientific community.


Nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide together at a very high speed and form a new nucleus. For light elements like hydrogen or helium the fused nucleus weights less than the sum of the original nucleus. The missing mass is released as energy in accordance with Einstein's mass-energy equivalence equations. Fusion is the process that powers active or "main sequence" stars.

UKAEA Graduate Scheme?

Has anyone in here done the graduate scheme at the UK Atomic Energy Authority in Culham? I recently finished a Master's degree loosely related to nuclear fusion, and I am intrigued to find out more about it. I have a background in applied mathematics, namely applied PDEs and MHD.

Could a FRC be combined with mirror?

The configuration of TAE and Helion is FRC, but their device seems like a mirror, as WHAM's device.

Does this means FRC and mirror usually combined together? How to tell them apart?

Shine Fusion: attempting to produce medical radioactives using .. fusion?

I'm trying to figure these guys out. they say they will be making 'stuff' (medicine application, energy sector application?) by using Fusion to produce... Fission products. Sorry, fuzzy on the details. but they say they'll be using D/T fusion (Deuterium/Tritium).

https://www.shinefusion.com/

Are their ideas sound? What does r/fusion think??

Couple of fusion ideas

Forgive me if i am wrong because im not super knowledgable on the subject, but I was wondering if it was possible to build a tokamak out of small strands of conducting tiles. i figured you could control surface level turbulence like suppressing elms before they became a problem. Also I was wondering if you could reduce turbulence by using directed energy to heat the plasma uniformly heated and the pockets so the turbulence is the same temperature as the less turbulent plasma.

Thank you for your time and please be nice if i am wrong as i am just a idiot.

Zap fus

Last year the Zap energy FUSE-Q fusion reactor achieved its first plasmas. The original schedule was to show net energy gain with this reactor by the end of 2023, which obviously didn’t happen. Since the report of the first plasmas there has been no updates on FUSE-Q. The only research articles released by Zap have been about the older FUSE reactor.
Does anybody on this site knows what happened with FUSE-Q, if the reactor works somewhat as intended, or if it has failed, or when they plan to release any results from that reactor ?

Last week Helion applied for a permit to build a 47-foot exhaust stack for the Polaris building.

"The system will in the future connect to an exhaust system, which will be permitted in the second phase of the project."

The height of the stack makes me think that it will be connected to their exhaust gas processing system to reduce exposure to any uncollected tritium.

More information on their exhaust gas processing installation should come in later permits.

Used Process systems code

Has anybody able to run PROCESS systems code developed by UKAEA ?

Link: https://github.com/ukaea/PROCESS

User guide: https://ccfe.ukaea.uk/wp-content/uploads/2019/11/A-User-Guide-to-the-PROCESS-systems-code.pdf

I am very new to this, I needed to build fusion reactor simulation for my master's research.

Junior Level Position at Kyoto Fusioneering

Just had a brief interview with Kyoto Fusioneering and while I’m not a great fit for the position, I thought it might be of interest here:

Position title: Graduate Fusion Engineer Masters degree required https://kyotofusioneering.com/en/joinus#requirementList

The ideal candidate for this position should have direct engineering experience (hands on) in at least one of the two areas below: Electromagnetism/Electrical engineering with Plasma physics a plus. Materials science/Engineering

In addition strong communication skills required. Mods not sure if this kind of post is allowed but wanted to share since it might be a good opportunity for a recent graduates to get involved in fusion.

Hey! I am going to build a demo fusor and need some help with a component.

Hello. I think I found a helpful component to my build, can anyone more experienced fact check that it looks alright and that it is what I think it is?

Link: amazon.com/Portable-Voltage-Electrostatic-Precipitator-Supply

Specification: 1.Model: CX-50 2.Input voltage: 180V250V(AC 50/60Hz) 3.output voltage: 2KV 10KV(DC)(continuously) 4.output current:0~5mA(DC) 5.Max output power:50W

To me it looks like a transformator, a rectifier, and a variac all in one. Id love to be able to use this instead of buying all those three things seperated. It would also save me a ton of money as this thing is only 35 bucks.

Its only 50W max, and by using Ohm’s law is would be 5mA(which I hope will be enough?) and 10kV which is alright for a demo.

Do you think ITER will become obsolete?

According to the fusion energy companies quoted in this article, ITER still has value, but it will probably play a more supporting role in the pursuit of the first commercially viable reactor. What do you guys think?
