Regarding human life, the worst nuclear power plant accident in the US was an explosion in Idaho Falls in 1961 at an experimental Army reactor that killed 3 people.

Regarding monetary cost, the worst disaster was the Three Mile Island incident, in which a reactor had a partial meltdown and released a small amount of radiation into the atmosphere. Although very expensive to clean up, no one was harmed by the incident. (For comparison, coal power plants release the same amount of radioactive material into the atmosphere every few days.)

The site is now in the process of decommissioning.
