Safety first…
In the first incident, highly-skilled operatives inadvertently drilled into the warhead's core, provoking a full-scale evacuation of Pantex. They later made a second Chernobylesque blunder by bodging a highly-explosive warhead part back together with tape.
Had they subsequently dropped the component, the likely outcome would have been a "violent reaction", with "potentially unacceptable consequences", as safety board chairman John T. Conway rather conservatively put it.
Pantex is operated by BWX Technologies Inc. The facility's website assures visitors that BWXT Pantex is "Maintaining the safety, security and reliability of America's nuclear weapons stockpile" through "Teamwork that delivers… Results!".
