What do you mean?
My response is poorly worded ... the damage level is "saturated". The key takeaway for me is that the energy and damage really have to be parsed separately. Although the shockwave energy may show up in another damage ... it may be also be lost completely. My initial thinking was that the shockwave energy would show up at least partly as increased heat damage.If you have linear relation between heat and damage then you are right. In fact, the pulse heat (IR/visible/UV) damage is demonstrating saturation - due ablation effects. To say simple, over-powered heat pulse spend most of its energy over threshold to heat smoke emitted from exposed surfaces, and therefore mostly wasted.
My mistake. I completely missed that you quoted trurle's post.My response is poorly worded ... the damage level is "saturated".

Except that the bomb itself will be vaporized, and since only a small fraction nuclear fuel is consumed in an explosion, most of the initial mass of the bomb will be ejected. I would think the vapor would initially be a plasma, which will cool as it expands, potentially giving electrons and nuclei the opportunity to recombine recreating the original atoms. When the electrons fall out of the continuum, the energy they lose will be emitted as radiation in excess of the prompt radiation from the fission reactions. Would all of that matter form a shock wave, albeit a weaker one than that which would form on Earth? Since electrons are much less massive than nuclei - especially the nuclei of heavy atoms like uranium - they would outpace the nuclei, so the atoms wouldn't be able to recombine. In that case, I would expect that there would be a 'shock wave' of electrons followed by a true shock wave of heavy nuclei. A thermonuclear weapon would eject helium in the form of alpha particles and and electrons, unburned hydrogen in the form of protons and electrons, and perhaps some lithium. However, these wouldn't carry the same kinetic energy as the actinides. I suppose one could always pack the warhead with extra mass that would increase the density of the plasma, increasing the punch of the shock wave.I doubt that there would be any shockwave ... a shockwave is a mechanical wave (like a sound wave) it needs a medium to travel in
Unless it was set off in the middle of a gaseous mass aka a nebula or a planetary atmosphere, or a dense part of the asteroid belt etc, there would be no shock wave Dave
.I don't get this 65% reduction. The total released energy is still the same. So the energy that didn't go into the shock-wave, must go somewhere else, like radiation. But it cannot just disappear.
