One of the less widely discussed issues with nuclear is that the bigger plants are all somewhat unique in their engineering particulars, which makes it more costly to maintain them. SMRs can be more readily standardised, which is expected to improve their economics as well as their cost to maintain.

I've been following the situation in Canada. Afaik the closest we are to getting SMRs is a plan to supplement power production at the Darlington, Ontario CANDU plant using SMRs of the GE Hitachi design. The utility is seeking regulatory approval on the first of 4, but they haven't broken ground yet to the best of my knowledge. Each would put out up to 300 Mw, so I guess the completed project would add 1.2 Gw to the grid.
Ontario gets around half its power from nuclear, and the current provincial government is gung-ho on building more capacity. While I am not opposed to the idea (they would need to build more anyway just to maintain that ratio in coming decades), the fact that it comes at the heels of them cancelling nearly every renewable energy project at the beginning of their term adds a sour note. These included those that were actually under construction, and tax money had to foot the bill on broken contracts. It was flabbergasting. I am cautiously optimistic about SMRs but they are still vapourware for the most part at this time.

the world’s first floating nuclear power plant
That's a weird thing to say, considering we've had nuclear power plants inside submarines since 1958.

Yes, Soviet/Russian technology, the posterchild for prudence and carefulness.

The Akademik Lomonosov was supposed to cost the equivalent of $232M, but ended up somewhere north of $700M all for a net electrical output of 64MWe. In that respect, it follows a familiar path for nuclear projects.
On a cost/kW basis, it's about three times the cost of wind installations. ($3625/kW vs $1300/kW)
The last co-gen plant I worked on had an output of 353MWe and cost about $450M, which was about $50M under budget.

When they say small, how small are we talking? The size of a sedan? A school bus?
