Yes, but demand isn't. And nuclear can't be trivially shut down, the reactor stays hot for quite a while and that energy needs to go somewhere (which is the whole point of the iconic giant cooling towers these plants have). So if demand drops rapidly and your reactors are going full tilt, the price of electricity goes to zero.
