In part of CA’s on-go series on useful (travel?) advice, I’m happy to bring you this story from Wired: How To: Dismantle””°an Atomic””°Bomb.

Disconnect the wires leading from the battery or the trigger/timer to the detonator. The battery will look like a battery; the timer is the part that’s counting down. Be careful: This is the trickiest part of the bomb ““ and where it’s most likely to be booby-trapped (the whole red wire/blue wire thing comes into play here). And for God’s sake, don’t fuss over the process in order to make the timer stop at something clever like 0-0-7.Remove the neutron trigger. This will be a small disc or ball. Don’t eat it ““ it will be made of polonium or some other highly radioactive material, which initiates the chain reaction. After this step, the bomb can still detonate, but it won’t be Hiroshima.
Remove the conventional explosive. It’s the first part to go boom. In government weapons, it’ll likely be some type of IHE (insensitive high explosive), which is fairly safe to handle. But in an improvised device, it might be considerably more unstable. Just keep a steady hand “¦
Separate the U-235 masses. These will be two small but very heavy chunks of metal ““ an isotope of uranium. If they get too close to one another, the combined critical mass will flood the area with radiation, and you will die. Kept apart, each emits only relatively harmless alpha particles ““ you could even handle them without gloves if necessary. Put each piece in a separate metal box and call the authorities.
If these tips don’t work, give us a call and let us know what we got wrong.

cirby added these pithy words on 07 Oct 06 at 1:53 amOf course, this would only work for a U-235 bomb, and only if the bomb maker was a complete idiot.
The best and quickest way for an untrained person to “disarm” a nuke would be to blow it up or pour a conducting fluid into the mechanism. That way, it’ll still explode, but at least the full-out fission reaction wouldn’t be complete.
Of course, you’ll be dead (probably), but the other hundred thousand people in the blast radius have a much better chance…

If time really counts, and you’ve got to disable the bomb, I’d say find someway to keep the fissionables away from each other. Even if the IHE detonates, a dirty cloud is preferable to a glowing hole in the ground and 400 mph winds. -cp
