Sure, but it's very little fuel when compared to coal, gas or oil. Raw Uranium is just 14% of the total energy price for nuclear energy, which means that doubling the price of uranium would add about 10% to the cost of electricity produced in existing nuclear plants, and about half that much to the cost of electricity in future power plants. For Coal/Gas plants, the fuel cost is the main cost by far.
Btw, Russia is not the main producer of Uranium. First is Kazakhstan, then Namibia, Canada, Australia and Uzbekistan
For sure, and likely they won't help or help marginally to reach 2035 goals, but they can definitely help to reach "net-0 by 2050". Modern nuclear power plants are planned for construction in five years or less (42 months for Canada Deuterium Uranium (CANDU) ACR-1000, 60 months from order to operation for an AP1000, 48 months from first concrete to operation for a European Pressurized Reactor (EPR) and 45 months for an ESBWR)[47] as opposed to over a decade for some previous plants.
The cost of building new power plants is mostly impacted by delays and overruns, which are often caused by policy changes. For instance, Canada has cost overruns for the Darlington Nuclear Generating Station, largely due to delays and policy changes, that are often cited by opponents of new reactors. Construction started in 1981 at an estimated cost of $7.4 Billion 1993-adjusted CAD, and finished in 1993 at a cost of $14.5 billion. 70% of the price increase was due to interest charges incurred due to delays imposed to postpone units 3 and 4, 46% inflation over a 4-year period and other changes in financial policy.
The costs of decommission are included by law in the price of the energy, and the Nuclear Power Plant owners are required to set aside that money in order to smoothly decommission the plant with no extra costs.
There are secure enough strategies to contain the, honestly small, amount of spent fuel we produce today. It's just that it's scary and no one wants a nuclear deposit in their backyard, but in reality it's still orders of magnitude safer than dumping millions of tons of pollutants in the air with coal power plants.
Based on their model, the researchers estimated that 1.37 million cases of lung cancer around the world will be linked with coal-fired power plants in 2025.
How many people do you think will die in 2025 due to Nuclear Energy? How many per MW/h? And I remind you that Germany closed all Nuclear Plants before closing all Coal Powered Plants.
I'm not sure why you are spending so much time comparing nuclear to coal based plants. If you wanted to make a compelling argument there you'd need to compare it to renewable energy sources. I totally agree that we need to phase our coal based plants as fast as possible.
The price for the fuel isn't so much the issue but availability or rather dependency on outside powers. I didn't say that we would depend on Russia directly. But the way the world is changing right now you never know which nation goes haywire next. I'd much prefer the option with less reliance on other states for our power sources.
The delay and cost is definitely subject to policy and policy changes. But today no-one can guarantee that we wont do those and in effect have a delayed and very expensive project on our hands. I'll remind you of Stuttgart 21 or the BER or any other bigger projects Germany has been dealing with as long as I can remember. I have no faith that a reactor would magically be built without any of the issues those projects have.
I have yet to see a convincing strategy to explain humans in a few thousand years what we buried in these tombs. It just doesn't seem plausible. And even if we find a few suitable places are we sure we will find more when those have filled up?
Because Germany decommissioned their Nuclear plants before they did so with coal plants (or gas plants, which they keep building)
Sure, but price is a function of availability and demand. The price is low because it's pretty available and the demand is nothing like that of oil, LNG or coal. Plus Canada and Australia have some of the biggest reserves in the world (3rd, 4th) and they are western democracies we can rely on. Also, Uranium isn't bought JIT, but it's bought years in advanced so that it can be enriched and stockpiled, this means that it doesn't feel the price fluctuations that much.
As for renewables, I don't know if you've noticed, but most solar cells right now come from China, if they were to stop selling tomorrow (for one reason or another) we'd be kind of screwed anyway. Maybe a good mix and diversification is the best answer here. And yes, I know that you don't need China to keep operating your solar cells, but they are kind of needed right now to make the transition, new cells will be needed to replace old ones, and we also need batteries, which they are now leading production of. Unless we move manufacturing back (which we should do, but that's a decades long process we can't possibly rely upon) we are still reliant on an external state to undergo the ecological transition.
Maybe it won't really be necessary, some 4th gen nuclear reactors promise to be able to use spent fuel for their reaction (also Thorium, which is extremely more abundant than Uranium). These are now like fusion reactors, which are permanently 20 years away, but we are building them right now. Some of these plants will go online this decade afaik, and if they deliver, many more will surely follow next decade.
Using spent fuel should shorten the estimated containment time from tens of thousands of years to 300 years, which should be enough to just say, bury them and leave.
This is an issue we might be able to fix without hoping for magical technology. Also because it doesn't touch only this argument, but pretty much everything happening in the country. We can't just say "Germany can't make any big project" and leave.
Yeah but that is done. There is no way to reverse that. The thing we need to talk about now are options to coal based plants which are nuclear and renewables. So if anything we need to discuss the pros and cons of those two. Noone here is saying that the coal plants are a good thing.
Germany had one of the biggest sectors for photovoltaic cells. They are closing and I agree we should be moving production back to europe. Right now there might be enough knowhow left so it does not take decades to do so.
If we can actually use spent fuel. That's a big if I don't want to gamble on. Also 300 years is still a very long time. 300 years eralier society was so much different than now, we can't possibly predict what's going to happen in the next ~10 Generations of humans.
My point isn't "do nothing instead of nuclear power" though. My point is that many smaller projects seem way more likely to succeed in the bigger picture even if some of them fail or are delayed, which is what reneweable energies are suited to. The success of the transition is also about people being able to trust into the success of the project. And I don't think many people have a lot of trust into germanies ability to bring big projects to a successful end. I'd like that to be different, I do, but that's just not what I have experienced in my lifetime.
Kazakhstan isn't exactly any better than Russia. They're Russia's little puppet.
