Sorry, this wouldn't work at all. I don't have time and desire to verify their neutrino beam / neutron shower calculation, but they want to detonate bombs by raising the core temperature to 300C, assumed ignition temperature of surrounding explosives.<p>This doesn't work, because: 1) you cannot detonate explosives there by simple ignition, 2) you need a very precise timing for simultaneous activation of all detonators, to achieve the smooth shockwave front, and 3) even if all this somehow happened, you just can't explode the bomb just lying around AT ALL, as it is not in pre-critical configuration yet. There are many things that need to happen simultaneously, in exact order and with nanosecond precision. There are PAL devices that provide encrypted timing differences to the detonation controller by loading external codes — without these codes, it is physically impossible to achieve nuclear explosion, even if you somehow activated all other things from pre-detonation checklist. Etc etc.<p>Not to mention that in the real bomb, there is much less plutonium than 10 kg they have mentioned.<p>I assume the rest of the paper is of similar quality.
