I have no idea if a sub’s reactor could handle that but, there is a nuclear aircraft carrier off the coast. I would think, if such a thing could be done, that the carrier’s reactor would be the better choice. Still, it doesn’t sound like the best solution out there.
The cooling systems of the reactor rely on the sub being under weigh.

No, but for a different reason. As pointed out, you can run a sub’s reactor without the sub itself moving - unlike some earlier surfae ships which did use scoop injection.
but .... (long but follows) the nuke subs only have two relatively small steam turbo-generators. They create 440 volt power - which isn’t isn’t easily compatible with the city’s 60 Hz 120 household and 12,000+ volt distribution systems. Sure, some piers have transformers so the city power gets lowered in voltage to a ship’s voltage requirements (so a ship can turn off its propulsion plant when in port) - but those transformers are limited in size and capacity.
Better to have a cruise ship stop in and use its generators (far larger than a sub!) or an aircraft carrier. Again - you have get the power back FROM the pier to the city.
Best is to let the SeaBee’s or Army build their existing shore-based portable power plants. In other words, use defense dollars (and military time and people!) to help Obama make Obama look good for the media to crow about.
Nuke subs are not the right answer. It would be like plugging an extension cord into the side of a C-5 and running the C-5’s engines to create 120 volts. instead of flying the C-5 to bring in 500 small gas generators. And the trucks and gas carriers to fill them and move the small generator around..
