A fission power plant simulator lets you have fun playing through a meltdown disaster scenario. A fusion power plant simulator is "worse" because it takes away the "fun" of meltdowns. The humor is in reacting to the simulator as if it were a game (some are, but this one isn't).
Eh, a core-containment failure (in any magnetically-contained system) would involve superheated hydrogen getting friendly with oxygen. That, in turn, would give neutron-impregnated barrier materials a free ride on propellant. It's not strictly a melt down. But it's in the same practical category of failure.
Ths is a massive misunderstanding of the technology. First of all, the amount of hydrogen in the reactor is tiny. The magnetic confinement severely limits the density of the plasma. The inner containment vessel is a ultra high vacuum chamber. The chemical energy that would be released by a reaction between the hydrogen in the reactor amd oxygen from the air would be less than what is released by popping a hydrogen filled balloon with a lighter.
The truly concerning failure modes would be related to release of radiation or activated materials. But that would require damaging the reactor in ways that the reactor is incapable of imparting on itself.

Thanks for the correction. If you're breeding lithium in the walls, might that be an incendiary concern?
There seems to be a number of different prototypes of blankets, but the average operating temperature seems to be 300-700C. Adding oxygen to some of these designs while that hot may cause metal burning. This said, many of them are ceramic designs and would likely resist combustion.
With all that said, it seems to be way less 'dangerous' material than would be in your average nuclear reactor, making it more of an industrial accident versus a planet contaminating mess.
The breeding blanket is entirely contained inside a vacuum vessel, so there isn't any oxygen to react with. Also, the are many blanket designs, but the lithium is never present in its elemental form (precisely because it would be very reactive), but in a stable chemical bond with some neutron multiplier (like lithium-lead alloys or beryllium ceramics). In some design the lithium is even immersed in the coolant itself, which is high pressure helium, so it's not going to ignite in any reasonable way.
> breeding blanket is entirely contained inside a vacuum vessel, so there isn't any oxygen to react with
When the vessel works. If the vessel breaches, that lithium could ignite. Note a showstopper. But I suppose a risk to be thought about by the engineers (probably not by policymakers).
There's only a few grams of hydrogen in the reactor's plasma, it's reaction with oxygen wouldn't be much more exciting than just losing containment. There are engineering challenges that have to be addressed but no worse than the 6 MW research reactor I used to walk by every day to my college classes in the middle of a dense city.
The proliferation risk of someone using the neutron flux to produce an atomic or dirty bomb are real but that exists no matter where it is.
Radiologically? Pretty much nothing. The regular industrial safety concerns will matter more.
The plant will have some tritium, and the material in reactor walls will get activated by the neutron flux. Some of the activated materials can disperse in case of a catastrophic explosion (e.g. a couple of large airplanes being flown the reactor building).
But the material of the walls is not volatile, so it'll stay on the site. And tritium is very volatile, so it'll quickly disperse to safe levels. You'll be able to detect them with sensitive equipment, but it won't be dangerous.
Neither Ukraine nor Russia are using manned aircraft in any significant ways. They are at most used to lob gliding bombs from far behind the front lines.
> And naturally F-35s on that theatre would have been a game changer making mass strikes on Moscow possible.
And then what? Kyiv has been under relentless strikes from drones and missiles for 5 years. And Moscow was hit by Ukrainian drones several times.
You'll need to suppress all the anti-air defenses first, and it will likely be too costly.
It remains to be seen how well F-35s actually perform in that role against an adversary with modern anti-air defense and with modern drone-based tactics.
Both Russia and Ukraine learned to avoid concentrating forces, so what are you going to strike? Use an F-35 to attack a single Jeep with a mounted machine gun? F-35 has limited range and carries very limited armament, so you can't just carpet-bomb everything. At some point, you'll need to use much less survivable heavy bombers.
Oh I love shopping lists, let's see. The FSB HQ, SVR HQ, Rosgvardiya HQ; tens of Army offices across the city. Roscosmos HQ, listening stations for the satellite network. Precision mechanics, optics and electronic foundries manufacturing sites in Khimki, Lubertsy, Lytkarino, Krasnogorsk and Zelenograd. Kosmos concert hall on Militia Day. Am sure there's more good spots along Rublevskoye highway too.
And if there are still some GBUs left after all that, the Kremlin and even the bloody Mausoleum.
_All_ the classic anti-air is useless against drones, as the US also found out. It can be easily saturated, and ground-hugging drones are not a good target for missiles anyway. Ukraine is now using interceptor drones for this reason.
The issue with stealth fighters is that they have nothing to do. The enemy can launch barrages of drones from hundreds of kilometers away, outside the F-35's effective range. Or if you're moving ground forces, they'll be attacked by mobile units armed with short-range drones, also making F-35 less than useful.
That's also the reason why Russia right now is at a full stalemate. Its only semi-working strategy is to filter infantry through killzones that can be tens of kilometers in depth. Russia can easily bomb Ukrainian positions with gliding bombs or missiles like S-300. But there's just nothing to bomb, Ukrainian army is spread out.
The US has not found that out, they knew it, that's why things like lasers and other systems have seen so much development.
Yes the war showed some new aspects, but relentless low capability drone attacks is not the same as flying an F-35 into enemy air space and bombing their critical resources with high accuracy thanks to sensors.
Mass manaufacture and drones and such need to be take into account in the future, but when it comes to what is easer to counter, mass drone attacks or F-35, ill be money on the mass drones being countered first.
There are already many system that can deal with drones quite well. Old school FLAC with improved sensors, fast shooting system, even cheaper drones as counters and of course lasers and so on in the future.
Yes S-300 doesn't deal with drones either, but its pretty clear what to develop to counter-them, how to counter F-35s is not nearly as easy.
> The enemy can launch barrages of drones from hundreds of kilometers away, outside the F-35's effective range.
If they are doing that these drones are no longer as cheap and if you fly against modern anti drone weapon that have costs of a few $ per shot down drone, the economics is no longer in your favor.
> The US has not found that out, they knew it, that's why things like lasers and other systems have seen so much development.
Yes, the US was not prepared. The laser systems were nowhere to be seen, and there are no interceptor drones on the field right now. Or at least not in the quantity needed to protect valuable targets (like AWACS planes).
Also, lasers are just a waste of resources anyway. They only work when the LoS is available, and tracking a small target over large distances requires highly precise machinery. Exactly something that you want on a battlefield.
> Yes the war showed some new aspects, but relentless low capability drone attacks is not the same as flying an F-35 into enemy air space and bombing their critical resources with high accuracy thanks to sensors.
F-35 is not designed to bomb critical resources. It's a fighter jet.
> Yes S-300 doesn't deal with drones either, but its pretty clear what to develop to counter-them, how to counter F-35s is not nearly as easy.
It's not the point. The enemy doesn't need to suppress F-35s to keep launching salvos of hundreds of Shaheed drones into YOUR critical infrastructure that you can't protect. That's the whole point of the article.
Not to argue with most of your points (which I agree with), but the F-35 is really meant to be more of a fighter-bomber than a true air-superiority fighter. It's not really in the same class as F-22/J-20/Su-30/F-15EX kinematically, and that's fine because counter-air really isn't its role.
> tracking a small target over large distances requires highly precise machinery. Exactly something that you want on a battlefield.
Lots of things on the battle field now, would have been considered highly precise in the past. The current generation is more relevant for ships.
> F-35 is not designed to bomb critical resources. It's a fighter jet.
No it isn't. That's complete nonsense.
> launching salvos of hundreds of Shaheed drones into YOUR critical infrastructure that you can't protect.
And my point that you ignored was that technology to do mass shoot-down of Shaheed is much more likely to exists then technology to prevent F-35.
If its a poor economic war the question is if your interceptor can be cheaper then what its preventing. And drones while cheap are not as cheap as, bullets, lasers or smaller drones.
And you say, 'launch from greater distances' that also comes with longer time to intercept because these things don't have radars and aren't that fast. Plus launching ever larger drones at longer range also increases the cost per drone.
But they can't do and F-35 can is that they can go in and take out exactly the vital air defense and other points so that your other aviation assets have an easier time.
Any conception that war in the future will just be two mass manufacturing lines splinting drones at each other is silly, technology and stealth have a major roll to play.
> That's the whole point of the article.
I think the point of the article likely is to convince people that drones should get more funding in the full knowledge of that F-35 wont go away.
Its funny how some of the people who know a lot about this stuff are still going forward with other next generation planes despite cheap drones existing.
Cheap drones are new part of the battle field, but just like with most weapons, the old stuff doesn't go away. Tanks and rifles are still useful. And so is the F-35 and stealth jets.
Strike the stuff that can't move: government offices, factories, bridges, dams, power plants, ports, logistics hubs. The heavy B-2 bombers are themselves quite survivable, and were in fact used in the initial strikes.
Government offices are hardened against strikes, and they are going to be located beyond the reach of F-35s anyway in case of a war with Russia or China.
> bridges, dams, power plants
A war crime, btw. Bridges and dams are also notoriously hard to destroy.
> The heavy B-2 bombers are themselves quite survivable
They are, but less so compared to lighter aircraft.
It's like watching salami slicing happen in real time. It also forces a dilemma on Russia. Every move of GBAD to Moscow to defend against drone leaves an airfield uncovered. Move some to airfields and it leaves a refinery open. And on and on.
And at the same time, drones are eating the AD every day, with videos of multiple strikes often coming out on a single day. Most in Crimea, but now more often also elsewhere.
An it shows with how the drone attacks on oil ports, refineries a even on navy ships in harbor have been successful lately.
Somebody else was likely sleeping in the living room already. The reality of living conditions in the USSR was harsh.
You were typically allocated spacious 9 square meters (96 sq. ft.) of living space per person, with an additional 18 square meters for the head of the family. So a 4-person family would get about 45 square meters (485 sq. ft.)
And these were _typical_ numbers, not a guarantee. Plenty of families had less space.
I got a Kindle Oasis in 2018 and it was a perfect device for me. Cellular connectivity, Bluetooth support for audiobooks, and synchronization.
I could start reading on my phone, then transition to listening in my car, and then pick up reading on Kindle. And it worked well in a literal airplane. I didn't have to faff about with WiFi passwords to sync to the latest page, thanks to the cellular connectivity.
And now Kindle devices lost cellular (why?!?), lost physical keys (facepalm), and are getting worse and worse UI/UX-wise.
Look, we're using Uber Eats to order food for "free food Tuesdays" in our office.
I'm struggling to not puke using their interface, and a couple of times I gave up ordering even though it was free.
Every click can take 2-5 seconds to be processed, without any indication. Menus glitch. I once got 2 copies of my order because I rage-clicked the "Finish" button several times.
So you're trying to do high-end AI when you can't make a basic fucking form-based webapp work?!? What do you expect?
I previously worked at Uber and there were constantly internal complaints that went unheard regarding the enshittification of the UI. Since Uber really hasn't had much innovation going on in the last few years, (imo) frontend teams are forced to justify their existence/employment by adding changes to the UI that look great on paper but in practice are not.
As for all the associated bugs, it's inexcusable and I'm still unsure how most of them even get by QA. Engineering culture there has gone downhill; I saw the majority of great engineers leave during my tenure after being fed up with the endless cronyism + promo-project culture.
Some people spend ages writing a cheat sheet with the intent of cheating on the test but realise that because they wrote it down and / or tried to summarise it they actually learned the materials.
