Nuclear reactors?

[samatman]

Arguably, the existence of nuclear reactors which don't fail safe under any contemplated crisis is a hardware bug. It's possible to design a reactor that can be ruptured by a bomb or earthquake, which will then dump core into a prepared area and cool down.

This kind of physics-based safety is obviously not possible for airplanes.

What triggers the core dump? Humans? Software? Are there detectors integrated into the walls?

[samatman]

Physical rupture of containment.

If all electronics fry simultaneously, then the reactor core cools in-place.

I should have said “commercial airplanes are among the most important and critical things that use software.” It’s obviously difficult to determine the objective most important use case.
