push the big red button and see it dismantle itself (along with the whole neighbourhood)

What if there's no "big red button"?

read the manual under the chapter "How to detonate"

or simply remove the plutonium 238 before it reaches critical mass

You don't reset Atomic bombs, you blow them up.

but u may have put it in the wrong place and need to quickly stop it and reset it.

If you're making an A-bomb and "put something in the wrong place", you shouldn't be making it in the first place. :wink:

Actually , less car eis needed with an A bomb than for a conventional one. Conventional bombs often have relatively unstable igniters. For obvious reasons this are much more stable and less likely to go off by accident in a nuclear warhead. In addition, if you were to set it off by accident, a nuclear warhead would not undergo a chain reaction and hence only the conventional explosion from the ignition stages would do any damage (not counting the radioactive contamination due to spread of enriched uranium / plutonium. ). In order to set of a nuclear blast all ignition segments must be triggered synchroneously and thsi requires quite sofisticated electronics. The only way you could possibly detonate the warhead by accident would be if you , by accident, were to expose the circuits to static electricity such that the circuit mistook it for a propperly received detonation code (anyone want to calculate the probability of that happening? ) .

Seen from this perspective a Biological or Chemical weapon is mor etricky to deal with as any mistake could release its paylaod which would have quite disasterous consequences.

Depends on the type of bomb, implosion or gun type, and the safeguards on the detonator.

Gun type should be pretty straight forward as you could simply saw the thing across and block the path of the "bullet" . Implosion types you could probably just blow to pieces with another bomb as the explosion would hit one side of the hollow sphere first and thus blast the material into pieces without a chain reaction ever taking place.

cut the red wire


or is it the green wire???? :biggrin:
jesus the physics syllabus has changed quite abit, is this meant to be a proper practical now, certainly beats playing with springs :biggrin:
