In the short run, sure. In the long run, cheap power builds its own demand. A country that commits to a certain amount of nuclear baseload, even if run at a loss in the short term, is injecting a very real industrial subsidy into its system. (The way to ensure you don’t get a dog is to subsidise long-term loans for private borrowers. They still need to make a profit someday. But you reduce the time value of money for them.)
The investment doesn’t make sense for a non-nuclear power. But if you’re already producing nuclear waste at scale for your military, it’s a little silly to pretend you’re safer without a civilian reactor in the middle of a desert while all manner of subs and ships patrol your coast.
