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.
Current mainstream approaches include:
Magnetic confinement, used in tokamak, spheromak and stellarator designs
Inertial confinement, used at the National Ignition Facility
Electrostatic confinement, used by the fusor and Polywell devices

Hello everyone, I am a 18 year old student in germany and over the past year or two I have informed myself about the absolute basics of fusion via the internet. But I am aware that I only know absolute surface stuff and probably not even all of that and I would like to know more. Are there any good ways for an absolute beginner to get more information about Fusion? So far I've mostly found wayyyy to oversimplified sources that explain too little or sources that are far beyond my understanding.
I'd hate to make this long since it seems most likely that i just don't know something that would make this idea stupid.. Buuuuuuuuuuuut :D it's been rattling around my head for a while and i need to hear somebody give me good reasons why it wouldn't work. Just please, be honest and gentle xD
I've been watching this yt vid from Isaac Arthur
and under mechanism part 4:02 he starts going into rare quantum results that happen with diprotons which made me think.
If our fusion reactors can achieve higher temp then the sun and also don't cross the coulomb barrier then isn't there something else in effect as to how to increase the % success rate?
So here is the part that's been rattling in the old dust box:
To try to use quantum entanglement to boost the chance of that quantum result?
A bunch of lasers all around the fusion chamber that would hit the plasma field to try to increase that success rate?
Dunno.. Obviously i'm not a physicist :( just had to ask somebody who knows more about the topic.
p.s. forgive the spelling and amateurishness and all the other mistakes i surely made along the way in my haste to unrattle the dust bin
As the title states, what would the effects be both local and further away in the event of a containment failure on a fusion reactor? Would that effect ozone or atmosphere, potential for warminbthe planet rapidly?
Yesterday I learned in a web meeting, that one insurance plans not to insure fusion plants, obviously confusing them with fission plants, which have a totally different, much higher risk and hazard level. Andrew Holland with FIA wants to discuss this of course. - And in March there will be important talks of FIA and EU fusion organizations Fusion for Energy and EuroFusion regarding PPP constructs for fusion.

Hey everyone. I apologize if this is not the type of post that you normally see on this subreddit, but I could use some help and I'm OK if it costs me some karma.
I am working towards my associates in Physics, on my way to getting my PhD in Plasma Fusion. I'm currently in a technical writing class and our quarter-long project is a three part essay on what we'll be doing after we graduate: part one is a background essay explaining the area of research and its history, part two is a literary review summarizing and discussing the existing research that has been done on the area of research, and part three is a business use case that describes how the area of research will positively affect the industry or field of study.
The thing is, my first essay came out at 85% because I missed one of the explicit requirements. I realize that was a total miss on my part. So, to boost my grade I was hoping to get extra credit by doing an interview with someone in this field.
If you work in plasma fusion research and have time to answer a few questions about what you do, it would mean the world. DM me and I can send you my LinkedIn to confirm my identity, if you want.
I've written my questions below:
Thank you for your time.
I am currently interviewing for a senior year summer internship with CFS as a business analyst and although I know some about fusion and Helion vs CFS etc, I am concerned about the future of careers in fusion, specifically business roles.
I am very interested in development positions relating to renewable energy (solar, wind, storage) and already have a few offers for this summer for development positions. But now that I've started interviewing with CFS, I've become more interested in fusion. My main concern is the long-term viability of fusion and if I would pigeonhole myself by going straight into fusion out of college (even with how prestigious CFS is). I am mainly interested in project management but commercially viable fusion may never happen and if it does its 2030 at the earliest right?
Weighing these options, what do you all think? (yes I realize I don't even have an offer from CFS yet, just trying to gauge possibilities)
I thought they were supposed to be done upgrading a decade ago. How come they’re still fixing it? Or are they going to replace it instead with something more up-to-date like with HTS coils/etc?
I'm quite interested in contributing to the field and learning more about the topic. Where could I as a software developer contribute and is development of the field more concentrated in some geographical areas?
