About 20 years ago in the early days of the web I used to browse websites about nuclear accidents and the like. Needless to say lots of these have disappeared or changed since, and I think some interesting material is probably lost. One of the stories I read concerned two Russian sailors attempting to steal expensive metals from a nuclear device (which thankfully had had the physics package removed). As I recall the story the device was resistant to their attempts at deconstruction, which led to them escalating to employment of a hammer, which led to rapid atomisation of the sailors after the high explosive trigger was activated.
