    People who work in nuclear submarines are cheek-by-jowl with a bloody reactor.  Sealed inside a steel tube with a reactor.  Hundreds of small nuclear reactors have been operated all over the place by the US Navy for many decades without incident.

    The thing is, "losing it" implies a run-away criticality situation.   Reactors can be engineered to guarantee this can never happen, guaranteed by the physics of the fuel and reactor design.  Chernobyl was a reactor design that did not have this feature.  Even at that, it was not a "nuclear" explosion.  It was a power excursion that resulted in a massive steam explosion - without any kind of containment structure.  No reactor in the world could be certified to operate with a design such as this today.  

    A bomb must be upward of 90% fissile material.  A reactor uses fuel that is just a few % fissile content.  A CANDU reactor uses natural uranium, with no enrichment at all.  There is no way that a reactor can go up like a nuclear bomb.  It is physically impossible.

    The intrinsic nature of Power is such that those who seek it most are least qualified to wield it.
