ITER Talks (2): The ITER Blanket System
Ғылым және технология
In this second ITER Talks episode meet Rene Raffray, responsible for one of the most critical components of the ITER machine: the blanket.
The 440 blanket modules that completely cover the inner walls of the ITER vacuum vessel protect the steel structure and the superconducting toroidal field magnets from the heat and high-energy neutrons produced by the fusion reactions. As the neutrons are slowed in the blanket, their kinetic energy is transformed into heat energy and collected by the water coolant. In a fusion power plant, this energy will be used for electrical power production.
Designing, fabricating and operating the ITER blanket will provide important information for the next-step fusion reactor, DEMO.
Background information: The ITER Talks is a series of lectures on the Science and Technology of ITER and fusion, recorded by experts that are working on the ITER project. The lectures will span the science, technology, engineering, and project management challenges and other aspects of this complex endeavour. New ITER Talks will be posted periodically.

Excellent mix of overview / technical / summary content. Learned a lot. Thanks for putting this together and giving us a technical peek at such engineering feats.
A great presentation of a hugely complicated engineering project, amongst the great endeavours of mankind which one day will produce safe,nonpolluting electricity for all.Enjoy your retirement René but I expect you will follow the progress of this great endeavour that has been your main activity throughout your working life.
Thank you for the deliciously dense loaf of details, like a Christmas fruitcake for the technically inclined, very chewy indeed.
A very good talk, well explained. Those temp gradients are mind boggling let alone the radiation fluxes
Excellent presentation. Thanks for the indepth technical details.
super il me tarde de venir vous voir en personne et merci encore .
A little more context to add to this presentation: the cat shown at 0:40 is in fact the speaker's cat who goes by the name of Pikachu
Really a clear presentation: thank you very much. I hope we could ear you in future development updates.
This video is excellent and I really do not understand why it only has 304 likes :)))
In the reaction of the neutron with the lithium, only the lithium-6 isotope is shown. However, this isotope comprises only about 7.6% of natural lithium, the remaining 92.4% being lithium-7. Does it mean that the lithium has to be enriched to get the required breeding ratio?

In general, yes, lithium does have to be enriched to have a higher percentage of Li-6 to produce a tritium breeding ratio larger than 1, however, if you have very high energy neutrons (above 2.8 MeV, like the 14.1 MeV DT fusion neutrons), Li-7 can also breed tritium by taking up that neutron, fission into an alpha particle and tritium, plus a neutron. This process consumed energy but not neutrons. With a better neutron multiplier, we can make a natural lithium breeding blanket work. Both heavy water based and helium cooled ceramics have been studied. One might also add a fission blanket (for example to burn fission waste fuel) that will multiply neutrons better than lead/beryllium, and that will make natural lithium work as well
27:55 if i'm not mistaken - explosion bonding/welding, is the craziest thing I've seen used to bond two metals. Highly recommend for anyone to check out

@Cool Baby thx man, didn't know that
Can u say blanket any more times🙂🙃🙂 'but' seriously love ya work I hope humanity can get back on it's feet. We can only go... forward not backwards... just forward 👽👽😉
Ce serait cool d’avoir des sous-titres français !!! Mon anglais n’est pas performant 😄…. Surtout quand j’entends parler de blanquette 😂 …
Who dreams up those unbelievable good titles? Well done you! Did you guys dump your social media staff? ;-)

I was also going to say this. The video titles are so bad, I'm not surprised that the videos don't get a lot of views. Wtf do titles like this one or "THE UPENDING" even mean? Get some media staff, please.
Be is very poisonous? It is a metal that can be very harmful when humans breathe it in, because it can damage the lungs and cause pneumonia. The most commonly known effect of beryllium is called berylliosis, a dangerous and persistent lung disorder that can also damage other organs, such as the heart.
Hi man jou wanna buy some helium 3 0.47 megv ronadam
I'm no genius but wouldn't it be smarter to collaborate on large projects like this instead of killing each other for scraps.... oh well.

And developing countries could modernize infrastructure without worrying about environmental restrictions. I mean could be a start to ending many disputes over water and resources... Because the internal combustion engine is still very popular in developing countries they ignore environmental restrictions because it's taking their people out of poverty and allows for the complex logistics of running a country. Idk I just think it's smarter than destabilizing each other.
In English please
Votre anglais cest tres pauvre pour la reste enchantes et beaucoup de success pense bien des chinois et des japonanais aussi donne beacoup de monnaie dedans cette recherche succes ronadam
