while the French are struggling miserably on nuclear power, imagine that the Russians have mastered all the following techniques: breeder reactors, small modular reactors (PRM) and well-maintained conventional power plants.

The Russians are particularly interested in PRMs because it allows them to colonize hostile lands, both on land (Siberia...) and on the sea (see Lomonosov floating nuclear power plant, and any kind of icebreaker / nuclear submarines)

Like everything related to nuclear, they are still somewhat dangerous and polluting devices, but the enormous autonomy allowed by fissile materials prevails, especially for expeditions at sea.

The French 900MW power plants have been the subject of 3 successive designs in about 10 years, the same for the 1300MW power plants.
Only 1450MW plants are all "identical", but there are only 4 units

And even if I am not a nuclear pro.... Our nuclear installations may be far behind those of the Russians... But in the meantime.... There is still not one under the sarcophagus....

the term "carbon neutral" is quite vague.

Even a solar panel is not currently strictly carbon neutral.

A partial point of view is certainly to consider that over its lifespan, it reimburses more than the CO2 emissions necessary for its manufacture.

But as long as we don't have an autarkic and renewable energy mix, nothing is strictly neutral in terms of CO2 emissions.

What is very troublesome are the heavy activities that cannot do without fossils.

For example the drivers of lithium tanks imagine themselves virtuous, while they move 2 tons of carbonaceous matter to move their small quintals of body mass. And if we go to see the sources that supply their electrical outlet...

Other sectors, non-exhaustively, air transport, road transport, construction machinery, cement works, metallurgy... how to make them carbon neutral? While they irrigate the entire manufacturing industry, including that of products considered "green" (solar panels, wind turbine blades, batteries...etc...).

In this entanglement, nuclear is a very mixed activity, if it is true that it emits less CO2 than fossils, it remains an extractivist mining activity with the originality of producing radioactive waste...

In any case, structurally, nuclear energy cannot provide carbon neutrality. It can only produce electricity by emitting less CO2 than coal gas.

good analysis! But it is necessary to distinguish the risks related to CO2 releases which are limited to the time of the release, just the time to be reabsorbed by the vegetation, still preserved, while the risks of nuclear power remain present for thousands of years and that nobody until now is not able to know the direct and indirect effects during these thousands of years on the terrestrial and marine flora and fauna.
Burial is just a bandage on a wooden leg!

I don't know if you noticed it, but the concentration of CO2 in the atmosphere is constantly increasing. Your "release time" is therefore just a big joke, an invention.
And for once,"nobody until now is able to know the direct and indirect effects during these thousands of years on the terrestrial and marine flora and fauna.That is true.

well, let's say that there is CO2 and CO2 and CO2... molecules reabsorbed by photosynthesis, others which go to storage outside the atmospheres which gradually become saturated (like the oceans) and those which are stored in the atmosphere.

The residence time for what remains in the atmosphere is enormous on a human scale, on the order of 10 years.
