Nuclear facilities aren't really dependent on market perception to keep their stock prices high - they sell power.
The terrorists won't do a better job of slandering fission than the oil & gas companies have done, and nuclear facilities and fuel storage make horrible terrorist targets. The facilities are explosion hardened by design, and spent fuel is essentially rocks. It would take a lot of work and explosives to make a weak, uninteresting, highly traceable, not too dangerous "dirty bomb". That requires supplies generally unavailable to terrorist cells, much less cells inside a nuclear nation. It also requires hazardous materials training and technical skills generally unavailable to terrorist organizations, much less embedded in a target area.
As has been the case for decades: the largest genuine threat from an action like that would be panic, and overreaction, from a riled up and ignorant population.
