  U.S. nuclear capacity factors: Stability and energy dominance
  Nuclear generation has inertia. Massive spinning turbines keep electricity flowing during grid disturbances. But nuclear generation also has a kind of inertia that isn’t governed by the laws of motion.
  Starting—and then finishing—a power reactor construction project requires significant upfront effort and money, but once built a reactor can run for decades. Capacity factors of U.S. reactors have remained near 90 percent since the turn of the century, but it took more than a decade of improvements to reach that steady state. The payoff for nuclear investments is long-term and reliable.
