To err is human. Frequently we hear this saying whenever something bad happens as a result of human action. Many nuclear accidents, and incidents, are the result of human error. The same is attributed to the safe automatic shutdown of nuclear reactors in Florida recently. It caused considerable loss and inconvenience to say the least to users and consumers, and the utility company itself, but the nuclear reactors behaved as expected and did not cause any accident.
Nonetheless some may regard that as nuclear accidents and regard safety issues as endemic to nuclear reactors. Unless the cause is made clear and explained to the public that misunderstanding may indeed take root in the mind of the public and nuclear energy will be regarded as unsafe.
Human error cannot be avoided, but measures that are put in place through advancement in engineering and technology minimize its effect on the system. Even so, it is best that the safety system is not challenged. Hence administrative means must be put in place to minimize that possibility. However, put everything in place, technical and administrative control, engineered safety features, and everything, without safety culture, those measures will not be effective.
Still, regrettably, any 'nuclear accidents' are taken by the public as technological flaw or weakness, not due to human infallibility. Road accidents happen every second and yet vehicles, as it should be, have never been branded as flawed. It is the driver that is at fault. Shouldn't the same be the case for nuclear reactors too?
