Well, barring any political issues I'm overlooking, I wouldn't mind Canada being contracted to build it.

280,000shp is quite a lot for 4-shafts, but in keeping with the base of Stalingrad Project 82.

Most shp per shaft was about 60,000shp on the Capitani Romani. 50,000shp per shaft seems a more conservative estimate for the time.

More fiddling...
