This is totally wrong. Nuclear has a very low marginal operating cost and to maximize return on investment Nuclear plants run at 100% of their allowed output irrespective of demand. Increases in the price of baseload power are unlikely as intermittent sources like wind and solar contribute a higher fraction of power. In particular, midday solar output will lower the baseload far below the current low point at night.
