> I think it does qualify as an industrial Russia acknowledges BN-800 problems, doesn't want to deploy it, and postpones its successor (BN-1200) to 2035 ( https://en.wikipedia.org/wiki/BN-1200_reactor https://en.wikipedia.org/wiki/BN-1200_reactor ) while investing on a different architecture (indeed: way less explored) => BN is not industrial. > It's right now the only commercial reactor that runs _completely_ on MOX. True, however this 10% is quantitative, it isn't qualitative step forward (burning MOX is not new), and therefore not the giant leap as sometimes argued. > CFR-600 in China will be the second commercial reactor capable of 100% MOX fuel operation some time next year It is a demonstrator , and "will be". There is quite a road to an industrial version (only planned now, and named "CFR-1000"). The real objective here may not be some future industrial reactor but to efficiently obtain military-grade plutonium ( https://en.wikipedia.org/wiki/CFR-600#Controversy https://en.wikipedia.org/wiki/CFR-600#Controversy ). Impact of Ukraine invasion: sigh, indeed, and from this point I don't see any path towards relief.

> BN is not industrial. I think we can agree to disagree on what "industrial" means. I think that the BN-800 reactor is an industrial reactor, just not a very good one. > while investing on a different architecture Not really investing. It's just that the committed BREST-300's financing will last a bit longer. But it will run out some time in 2025, and I'm pretty sure that they won't receive any new funds. The organization that develops it has some income of its own, as it is developing uranium nitride fuel (it's more uranium-dense compared to traditional oxides), but it won't be enough to finish the construction. > True, however this 10% is quantitative, it isn't qualitative step forward (burning MOX is not new), and therefore not the giant leap as sometimes argued. Pretty much nothing in the nuclear industry is a giant leap. It's all mostly a collection of small steps. Even lead-based fuel is not all that new, lead-bismuth reactors were used on submarines. Most of the complexity arises because industrial reactors pack several gigawatts of power generation in just a few cubic meters of space. That has to last for decades without significant maintenance to be cost-effective.

  > we can agree to disagree on what "industrial" means. I think that the BN-800 reactor is an industrial reactor, just not a very good one. Fair enough. IMHO 'industrial' here (power-producing equipment) means "ready for large-scale deployment". BREST: I didn't know, thank you! The path seems even longer than I thought. Small steps: indeed, and those small steps pace has to be bumped up if Gen4-proponents really hope to survive the renewables wave.
