25% efficiency? Seems very low.

Very high, to me, given its tidal, not pumped.

Err ... it's a floating nuke

Oh. That one. Well 37% is top thermal efficiency on most steam turbine
plant with BIG condensers, so 25% sounds OK for a steam turbine built to
actually *float*.

And not be too massive.




That's with steam temperatures of ~ 650C, this will be a water reactor
with steam temperature perhaps 315C.

Best fossil plant (without combined cycle) gets just over 40%, AGR a
little less, water reactors around 30%.

IMHO size of condenser is not really a limit for a floating system!
