Fission, fusion and nuclear waste

[sen-no-sen]

Hi,
JP Petit has not been credible for a long time.

Still, his outreach work is very relevant.
It seems clear to me that ITER will be killed in the bud, in particular due to the fact that it is a very monolithic project whose adaptability is weak.
Because even though ITER is not finished being built for a cost of 18 billion euros, a host of competing projects from startups or experienced labs (like Sandia) is launching a real fusion race, see the subject already created ::https://www.econologie.com/forums/energies-fossiles-nucleaire/la-course-a-la-fusion-nucleaire-t15153.html?hilit=la%20course%20a%20la%20fusion
There is certainly much more to be expected from secondary projects with a high level of adaptation than from such a mammoth.

You don't seem to have seen the documentary, because they talk about the different avenues of research towards fusion. Some will never reach the critical threshold of 100 millions of degrees.
At least look at the conclusion

[sen-no-sen]

It confirms what I mentioned ...

[izentrop]

So we agree
100 millions of degrees reached by the Chinese

The power injection in the experiment exceeded 10 MW, and the energy stored in the plasma was increased to 300 kJ after the team optimized the coupling of different heating techniques with the use of a system. advanced plasma control and prediction theory / simulation. Experiments on plasma equilibrium and instability as well as on confinement and transport, plasma-wall interaction and the physics of energetic particles have been demonstrated.

The team stated that it was able to perform a fully non-inductive steady state scenario with a high confinement factor, high density and an increased high energy confinement factor during test operations. One of the keys to this experience was the team's work to solve the particle and power exhaust problems, an essential element for high performance operation in steady state.

The results of these tests provided scientists with essential data for the validation of current heat exhaust, transport and drive models. The researchers focus on optimizing the third evolution fusion machine with a larger radium of 7 m, a minor radium of 2 m, a toroidal magnetic field at 6,5-7 Tesla and a plasma current of 13 mA. A team based in the United States is currently working on new magnets which, in their opinion, could help increase the production of power in their fusion experience. https://www.newsllive.com/technology/ch ... 0-22006444

Your documentary is naïve and optimistic. He only talks about the possible benefits of fusion and the different approaches currently being studied to get there, by not talking or not speaking very much, about the problems or dead ends that the scientists who work there will have to face.
In addition, it dates from an era when iter was only at the earthwork phase.

I find the videos of JP Petit much more realistic as to the chances of success, it explains well the problems which will have to face iter. And it highlights the fact that we seek to recreate the nuclear reaction of the sun without perfectly knowing what is happening and why.

The documentary has 8 years and the first plasma is expected only end 2025. https://www.iter.org/fr/construction/construction
JPP's publications are 5 years old and a great hoaxer who deciphers a hoax, that’s also big.

And then the Chinese publication is perhaps also a call for a budget extension? then "wait & see"

JPP has produced theories, they are refutable, it is scientific work, whether he is right or wrong.
Iter is based on proven conventional theories, and its obstacles are engineering problems related to the ambition of the project.
Everything is perfectly documented. In no case is it about mystifications, there are limits to amalgam.

Between E = m.c² and the first nuclear power station, which produced only a few hundred watts, 46 years passed. And yet, from E = Mc² we knew that we were going to be able to draw energy from nuclear reactions.
There would be an impasse with Iter only if the obstacle was theoretical, or practical but beyond the reach of techno conceivable in the short or medium term. This is not the case.

What you saw is only popularization. Like any popularization well done, it is easy to understand, except that we understand only a part of things. To have a relevant opinion you need a very good level of expertise in physics and digging, going to the level of scientific publications, this is not the feeling I have when I read you.

Ah, the troll is astrophysicist now ...

Yeah! its MHD period, UFOs and water engine "scientific work"? Mouarff!

For the rest concerning nuclear, I completely agree;)
