The vast majority of the cause of the 3 mile island nuclear meltdown was a moisture soaked compressor pump completely unrelated to any of the safety or emergency systems. With complicated failures, the actual fault is not always easy to detect.
It's reasonable to think that the controller might have contributed to unexpected descent past safety levels, or prevented them from recovering when warnings appeared.
You are technically correct, and that is the best kind of correct. I spoke from frustration, having grown up there. What i should have said was that there was no danger to the public, it was fully contained behind multiple redundant safety containments.
Its frustrating because i feel like that incident stalled nuclear energy in this country since then.
