The tl;dr is two halves of a beryllium sphere were supposed to be held apart by metal shims, but this guy didn't wanna use the shims and used a screwdriver instead. He also liked to fuck around with it as a show and, woops, one day fucked it up, the screwdriver slipped, the sphere slammed closed and because beryllium reflects neutrons the core went critical and dosed everyone present with lethal radiation
This was the second time this specific core was involved in killing people
Haha yeah
