TBH, probably the SCWR. They seem like the easiest to build without a lot of new surprises.

One like the BREST. https://en.wikipedia.org/wiki/BREST_(reactor) . Funnily my preferred reactor, the SCWR, would probably not be immune to some sabotage, specifically explosives around the reactor. But a reactor which uses a metal coolant would be. It just so happens that the nature of a SCWR cooled with water means that the reactor core has to be much beefier anyways, so it's a lot harder to really damage even if that was an explicit goal.
<eye roll> this is just bullshit.
Which Gen II reactors are subject to war, exactly?
The Zaporizhzhia Nuclear Power Plant, where one employ was killed by a drone strike?
What’s the status of the four new planned(?) reactors at Khmelnitski?
Wikipedia seems to indicate that two new AP1000 reactors are under construction.

A country that is having a hot war with its neighbour Russia(!) is getting the fuck on with it, while the rest of the Western world still thinks windmills are cool.
Potentially any of them. World governments aren't static. Mitt Romney was literally laughed at for talking about the Russian military threat in 2012.
> two new AP1000
These are Gen III+ reactors, which thoughout this thread I've been saying we should be building to replace the Gen II reactors.
If Ukraine was building new Gen II reactors you might have a point.
