> Astral Systems, a UK-based private commercial fusion company, has claimed to have become the first firm to successfully breed tritium, a vital fusion fuel, using its own operational fusion reactor. This achievement, made with the University of Bristol, addresses a significant hurdle in the development of fusion energy....
>
> Scientists from Astral Systems and the University of Bristol produced and detected tritium in real-time from an experimental lithium breeder blanket within Astral's multi-state fusion reactors. "There's a global race to find new ways to develop more tritium than what exists in today's world — a huge barrier is bringing fusion energy to reality," said Talmon Firestone, CEO and co-founder of Astral Systems. "This collaboration with the University of Bristol marks a leap forward in the search for viable, greater-than-replacement tritium breeding technologies. Using our multi-state fusion technology, we are the first private fusion company to use our reactors as a neutron source to produce fusion fuel."
>
> Astral Systems' approach uses its Multi-State Fusion (MSF) technology. The company states this will commercialize fusion power with better performance, efficiency, and lower costs than traditional reactors. Their reactor design, the result of 25 years of engineering and over 15 years of runtime, incorporates recent understandings of stellar physics. A core innovation is lattice confinement fusion (LCF), a concept first discovered by NASA in 2020. This allows Astral's reactor to achieve solid-state fuel densities 400 million times higher than those in plasma. The company's reactors are designed to induce two distinct fusion reactions simultaneously from a single power input, with fusion occurring in both plasma and a solid-state lattice.
The article includes this quote from professor Tom Scott, who led the University of Bristol's team, supported by the Royal Academy of Engineering and UK Atomic Energy Authority. "This landmark moment clearly demonstrates a potential path to scalable tritium production in the future and the capability of Multi-State Fusion to produce isotopes in general."
And there's also this prediction [2]from the company's web site :
> "As we progress the fusion rate of our technology, aiming to exceed 10 trillion DT fusions per second per system, we unlock a wide range of applications and capabilities, such as large-scale medical isotope production, fusion neutron materials damage testing, transmutation of existing nuclear waste stores, space applications, hybrid fusion-fission power systems, and beyond."
"Scientists everywhere are racing to develop this practically limitless form of energy," write [3]a climate news site called The Cooldown . (Since in theory nuclear fusion "has an energy output four times higher than that of fission, [4]according to the International Atomic Energy Agency .")

I guess if they succeed in producing more Tritium while at the same time the demand for Tritium for the "fusion" purpose goes down for some reason (like investors no longer betting on "fusion" to become a competitive energy source, or fusion of other isotopes becoming more interesting to use), then the currently small market for Tritium might see some price decline.
I for one am fine with the electroluminescent illumination of my watch, and do not really miss Tritium for that purpose.

Was tritium production really a concern in the first place? From what I've seen there's plenty of tritium produced in heavy water fission reactors like Candu: [1]https://en.wikipedia.org/wiki/... [wikipedia.org]

If you want a fusion power reactor, by far the most viable fuel is D+T. You'd need orders of magnitude more tritium than is could ever be extracted from trace fission byproducts.
The idea to obtain this much tritium is to use the extra neutrons from the fusion reactor itself to breed it from lithium. This is supposedly a demonstration of that process.

Several articles I found via Google noted that there's currently only about 20kg of Tritium in the world. Much more will apparently be needed for fusion reactors, and on a continuing basis.

I recently read about a 3D theory about time, and I guess Gravity is not really real. Somehow time is 3D and gravity is a byproduct of that. It does seems as good of a theory of most. With respect to Einstein, he seems to be on target.

Occam's razor though, keeps pointing me to the solution that we are living in a simulation. There is no solution to nonsense. I think that eventually someone will find a computer algorithm that gives us all of the answers to how atoms work, how gravity works, and explains time. It is a simulation.

There is a limitation, I think, to the speed of the computer that is controlling this simulation. Outside of this simulation, there may be no correlation between how fast mass moves and time.

It's interesting to theorize, but I certainly have doubts. A dream seems just as likely as a simulation. But what is doing the dreaming? Or if it's a computer, where is it running? Or is that computer also in a simulation? How deep do the turtles go? It seems like the answer would be none, one, or infinity.

I suggest that you theorize and dream. It is a gift we have, even if we are just a simulation or children of Gods. Let us theorize and dream.

I absolutely concur. I gave up on believing in reality some time ago. I prefer to explore the dream. I accept that it is impossible to understand everything or to know basically anything. I don't care whether people who seem crazy to me consider me to be crazy. About religion specifically, it really doesn't matter what I believe; what I do matters. People fighting over such unprovable beliefs seems more crazy than anything I've ever done.

Not much tritium (Score:2)
1e13 Tritiums / second * 3 * 1.6e-27 (atomic mass kg) * 3e7 seconds / year = 1.4e-6 kg/year. Tritium is about $30,000 / gm so this is about $4/year in tritium value.
They are aiming to get there. Doesn't sound economically viable.
Re: (Score:2)
I don't understand their market. CANDU reactors will produce enough tritium until 2050 [1]https://www.science.org/conten... [science.org] After that, we indeed need more reactors, but that's a long time for them to survive without anybody needing their product, as there is enough right now and it's basically "free" (as a byproduct of fission reactors).

Their reactor design incorporates recent understandings of stellar physics- it's the same understanding we used to have of stellar physics, but we still understand it.

... the "15 years of runtime" of their "operational fusion reactor" never produced any net energy gain - they were just after the isotope production, right?
Which means there is still only that tiny little detail missing before fusion reactors will replace all the other sources of energy... that detail being "becoming net energy positive, at costs where with the surplus energy can be sold cheaper than from established sources of energy".

Not quite. There is and had been a lot of plasma physics and material science research going on, all targetted at making commercially viable fusion a reality. It has been slow going since so much of this stuff is new and requires real research not just engineering. That "detail" is an end-goal to be attained when it realistically can be. Which is not yet, but it is getting closer.
That said, this is another hurdle taken and things moved a step. It also means the understanding of things has moved a significan

The first controlled fission reactor was in 1942. The Nautilus went to sea in 1955. That's what actual progress looks like.

Fusion has not been "around the corner" except in the fantasy of bad journalists. It has only bceome clear in the last few years that it will be possible with regards to plasma physics and material sciences without extreme effort. Commercial viability is likely but will take aditional decades. This is what actual experts have been saying all along.
And no, these are not "yahoos" or "no-name". These are actual scientists. Your disdain for them lets me suspect you are a no-clue MAGA.
