> Reactors themselves are the most expensive single part in the nuclear powerplant Do you have a recommended source for this? My impression was the vast majority of cost was outside the "nuclear island" of the plant.

Yes, you are right, most of the cost is still outside of nuclear island. But the single costliest part would still be a reactor, despite it itself being a small part of the plant cost. Turbines may've been more expensive than reactors for gigawatt scale plants decades ago, but large steam turbines went down in price considerably exactly because of mass manufacturing.

  Have you been able to find reliable pricing information for large steam turbines? I've been looking for quite a while and haven't managed to find a good source, especially for historical data.

    Unfortunately not except of "tens of megabucks" range

      Have you been able to find reliable pricing information about the turbines in the tens of megabucks range? Those are the ones that matter for the cost of grid power, I think.
