Is it technologically feasible to chemically neutralize nuclear weapons across the entire planet?

Question

Since we know how to make nuclear weapons work in the current environment could it neutralize them if we changed the environment?
I'm thinking of like darkening the sky somehow to alter radiation levels or spreading a biological agent that could prevent the nuclear reaction from occurring. Maybe an electrical storm could prevent the missiles from activating. Basically I want to know if there's a way to stop the weapons from working on a chemical or nuclear level.

Answer 1

I don't believe darkening the sky or changing radiation levels will have any impact on a nuclear chain reaction. A chemical agent may work, there are several nuclear poisons out there that are used in nuclear reactors to control the chain reaction; however, to get the level high enough to have an impact on all the world's nuclear weapons will probably have a devastating impact on the environment (i.e. kill all life.)

Answer 2

If you can wait a few billion years for the sun to expand to a red giant, I think the "environment" will change to the point where nuclear weapons are not effective.

Answer 3

Not with modern technology, and in such a large scale. God you know your global warming buddies are going to be pissed when they read this? I imagine any of the processes that you metion above would be pretty devistating to the world.

Answer 4

No
