Unless nuclear gets drastically cheaper, it'll never be good for on-demand generation. Because fuel is a small cost relative to capital repayments, operations and other fixed costs, operators run them flat out 24/7. You're paying to run the plant and you're paying your debts off anyway, so you might as well sell energy at any price since the marginal cost is minimal. They also don't start quickly.
