A lot of that can be reduced by innovative designs, such as having a modular reactor when you can slide out the vessel(or some other sub set of the reactor, not a nuclear engineer here) with the spent fuel and slide in a new one. Then you can refuel the old vessel to be ready for the next swap. You can gain economics of scale if you build a lot of plants in a region with the same modular design and have a central refueling facility. (yes I know I switch from ships to plants, same benefits accrue though)
