Is Jean-Marc Jancovici a c ...?

I ask you an innocent question (in the sense that it does not fit into the casuistry usually in use here): what do we do with the products reprocessed by the Russians?

That's a good question!
So to simplify, and ladle:
- spent fuel is reprocessed in France (La Hague)
- and we extract fission products and other actinides, waste, which will have to be stored (approx. 4%)
- plutonium (approx. 1%) which will be recycled in MOX, therefore in new fuel
- and the approx. 95% that remains is this famous "reprocessed uranium", which contains about 1% of U235, i.e. more than natural uranium (about 0,7%)
But we're like idiots with it, because we haven't set up the factories that would allow it to be reprocessed and enriched. So we store. This is not a huge logistical problem either, I let you calculate the volume of 35000t of uranium in total...for about 40 years of operation of the nuclear fleet.
On the other hand, the Russians have factories allowing it to be done.
So why not get him enriched in Russia?
And here I think I'm answering your question: enriched uranium comes back to France, while depleted uranium stays in Russia. Hence a significant drop (proportionally) in the stock in France.
But it's the same everywhere! All the depleted uranium resulting from the enrichment of natural uranium at the Tricastin plant remains in France, regardless of the country that placed the enrichment order. He takes back the enriched, and he leaves the impoverished. We must have around 400.000t of depleted uranium stored in France.
That said, in stocks of depleted uranium, you can go jogging every day while walking around the containers without risking much...

Conclusion: the Russians therefore make us doubly dependent:
1) on the fuel reprocessing chain
2) on uranium mining deposits

Note that the Russians like depleted uranium; they can make shells, or else breed via the BN600, BN800 and perhaps soon other fast neutron reactors.

In France, in fact, depleted uranium is stored "like idiots", a good expression Mr. Simple.

Conclusion: the Russians therefore make us doubly dependent:
1) on the fuel reprocessing chain. No, I explained that it was an "option"
2) on uranium mining deposits Nor was it mentioned.

I like clear and complete answers and precise facts that you don't twist your arms around... Thank you, Sicetaitsimple!

[Remundo]

Simple's answers aren't clear or complete.

Simple fashionable gesture "Everything is fine, Madame la Marquise" and drowns the fish.

I remember one anecdote among others, where Simple swore to his great gods that Linky would never be used in load shedding, bad luck, it was officially announced last winter when we were wading through the mire on the network.

The network held up with luck (climate not too cold) and imports that were as expensive as carbon.

it's not an "option" since you said yourself that we couldn't do it

Ah well, you who understand everything...

How come we don't do it to be mean to the dastardly Vlad?

Not sure I understand your question...
If it's "why don't we enrich reprocessed uranium in France?", I have already answered, because there are missing elements (factories) in the chain which would make it possible.

concerning the mining aspect, you must have forgotten another evening rich in scalp dancing: here

[Ahmed]

The answer to my question is clear and complete: This fuel cannot be processed in France because the option has not been made (and therefore not the factories that go with it): it has been chosen to have it done by the Russians...

[Remundo]

"and at the same time", as the other said... that we are not dependent..

Conclusion: the Russians therefore make us doubly dependent :
1) on the fuel reprocessing chain.

No, I explained that it was an "option"
