Removing human error / incompetent managers would be a good thing.
As chernobyl wasn't completly an accident, more an experiment gone wrong. They were attempting to run the reactor faster which was beyond its design specification by quite some margin. They went to far, and the reaction went out of control. Since control rods only have a finite ability to slow down a reaction.
Sadly when the reactor goes beyond a critical point thats it your doomed. The control rods could not stop the reaction from cascading out of control.
Designers incorporate hughe overheads in design so that the reactions can be slowed down even if the users get sloppy and let it run off.
Unfortunutly this was abused and they just went too far.

For new reactors there should be as quite right a fail safe which will over ride humans and lock down the core
