nuclear power plant operating history, although its small radioactive releases
had no detectable health effects on plant workers or the public. Its aftermath
brought about sweeping changes involving emergency response planning, reactor
operator training, human factors engineering, radiation protection, and many
other areas of nuclear power plant operations. It also caused the NRC to
tighten and heighten its regulatory oversight. All of these changes

combination of equipment malfunctions, design-related problems and worker
errors led to TMI-2’s partial meltdown and very small off-site releases of
