Not in its current iteration. The biggest advantage of natural gas generators is the possibility to ramp them up and down quickly, making them an ideal choice for peaker plants or load following. For nuclear, on the other hand, the options for throttling the output are quite limited - both physically and economically.

As a mitigation, combining them with battery storage would be an option, but then again it would still be cheaper to use wind or solar instead of nuclear as the source of energy.
