Today marks the 32 year since the accident in the very early hours of March 28th at Three Mile Island. I have in the past done a podcast on the subject.
There are a bunch of books on the subject, here is just a few:

The Warning: Accident at Three Mile Island: A Nuclear Omen for the Age of Terror
TMI 25 Years Later: The Three Mile Island Nuclear Power Plant Accident and Its Impact
