Destroying Nuclear Weapons with High-Energy Neutrinos

TheMatt writes "As reported by PhysicsWeb, physicists are proposing a "futuristic but not necessarily impossible" method of destroying nuclear weapons via high-energy neutrinos sent through the earth. Based on current planned efforts, this 'vast extrapolation' of current technology would use 1000 TeV beams. This would require a 1000-km diameter storage ring using magnets orders-of-magnitude stronger than currently available. The cost would be around $100 million-plus and it'd use 50 GW of energy, the UK's current consumption. (And the slight problem that the process might set off the nukes, instead of just melting them...)"

Dear North Korea

Dear North Korea,

Please allow me to express our deepest regrets and sympathies for vaporizing your country. Unfortunatly, while attempting to help save the world from future nuclear calamities, we accidently detonated all your nuclear warheads. We hope that this will not cause you any inconvenience, and we look forward to a prosperous trade relationship with your country at the conclusion of your nuclear winter.

Sincerly,

-George W Bush

That's obviously a forgery. Our president could never write something that eloquent. ;)

Shining a strong neutron source (in this case generated by neutrino beam passing through earth) on fission material would generate radioactivity and heat effect. The radioactivity would be much higher than the heat, so people around would see blue light and start dying right away.

Bombs would not go off, because the assembly of the core is always subcritical. Even if the high explosives of the implosion device goes off (because of the heat or fire, for example), the spontaneous nuclear explosion is very unlikely. These shaped charges in the implosion design have to be set off from a precise starting point at exactly same time. [Setting of the "implosion lenses" of the implosion device simultanneously was one of the major technical hurdles of the Fat Man development]

And, honestly I do not believe that such a strong neutron source could be realised using a neutrino beam.
