I'm a welder and cracks in big weldments can be a endless challenge. I hope they figure out a fix, and it has not gone through thermal cycles yet just the stresses of the welding process itself.
Rather funny (ironic?) that we have one article celebrating a big advance for ITER followed immediately by one laying out the multi-year schedule slip and cost increase also for ITER. Still think ITER will have a role to play as a research tool for studying extreme conditions in large plasma volumes that might assist in refining the design and manufacture of 2nd gen commercial reactors. Even if not the enormous sunk costs, international agreements and long term manufacturing contracts probably mean that this project will lumber on for a number of years until it joins the Supercollider in Texas as a giant mushroom farm.
There's a lot more to analyse regarding the ITER story, and I think we'll hear more on the subject in the coming months. They have already started a significant supply chain which has reached momentum, and some alternatives will be proposed to keep the project relevant within the present fusion environment. There will still be concerns by the funding partners, which will need to be reasured.
ITER is already obsolete and this is already recognised by the fusion community, eg in the U.K. where the emphasis is on compact reactors such as STEP. For ITER, the cost of something so large rules it out as a step towards a feasible electricity generating reactor. The best thing for ITER would be to stop the project immediately, the worse would be to continue and use it for DT experiments. After that who will pay for decommissioning the radioactive and tritiated structure ?
Please lead your titles with some reference to specific issues covered in the episode. It would prompt people more effectively to watch the current episode, and aid in searches of old stories.
“In any system of energy, Control is what consumes energy the most. No energy store holds enough energy to extract an amount of energy equal to the total energy it stores. No system of energy can deliver sum useful energy in excess of the total energy put into constructing it. This universal truth applies to all systems. Energy, like time, flows from past to future” (2017).
Проблема в том что использование вольфрама не решает проблем первой стенки. Опыты, проведённые на установке ГДЛ в институте ядерной физики именно не будкера показали, что при выпадении плазмы на вольфрамовую стенку в диверторе он не будет нежно испаряться, нет, - плазма выбивает целые капли вольфрама из стенки при этом.
That's why you'd like to prevent ELMs and disruptions. The issue here is the alternative they were working on was beryllium, which was worse. Indeed, alternative wall facing materials will need to be developed for commercial fusion power plants, but this is the best we have for the time being. ITER is just an experiment. A very expensive one to be just an experiment.
Thanks for bringing fusion news at one place! One suggestion though: I'd suggest avoiding reading the on screen text - it is so redundant and feeling strange to your viewers - I'm sure your viewers interested in fusion can read fairly well.
So many negative nellies in this comments section. Yes, ITER may be outdated by this point but every single ounce of data coming out of it can be used to fine tune the industry and lend advice for new, compact, future reactors. Its not a net negative, at this point its the Hubble to the compact reactor's James-Webb. Outdated, but still damn important.
useful to have one place to get a summary of fusion news

Nice video.

ITER will be obsolete by the time it is completed 🙁

Bonus news~
I want fusion to be successful as much as anyone, but ITER has only helped confirm the old adage that fusion is always 50 years away!
ITER is the new Titanic.
Morning.

How can fusion be an industry ?
Nothing at all is peing produced....
Our Indian Jessica Rabbit has spoken. 👍🏻😁
Great fusion news.
Space X needs to take over the ITER project!
Elon Musk isn't that dumb.
ITER's new timeline is unacceptable
