Neutrino Gun:

The researchers suggest sending a neutrino beam with an energy of 1000 TeV through the Earth to wherever the nuclear weapon was located (see figure). The beam would produce neutrons in a 'hadron shower' and would cause fission reactions in the plutonium or uranium in the bomb. These reactions would either melt or vaporize the bomb.

Such a high energy neutrino beam would be difficult to produce, the physicists admit. The storage ring would have to be 1000 km across - hundreds of times larger than the biggest present day accelerators. The magnets in the specially built muon storage ring would need to be one to two orders of magnitude stronger than those currently available to construct a realistically sized machine. Moreover, the cost of building such a device could be over $100 billion and it would consume 50 GW of energy - the entire power consumption of the United Kingdom.

Finally there is the risk, the authors point out, that the interaction of the neutrino beam with the bomb "could lead to a full explosion" instead of eliminating it.
