Two nuclear reactors? Love it! Double down on the political incorrectness.
Enterprise had 8, and the Nimitz class had four I believe.
Provides for tactical redundancy (with degraded performance) and maintenance down time. You could use one big plant.
Silly to have a nuclear powered CV. All the rest of the CVBG is conventional and has to refuel every 4 days. A reactor is an exotic way to make steam and the rector makes training and damage control exponentially expensive and dangerous. Leave the reactors to the bubble heads.
