      @wellerstein http://blog.nuclearsecrecy.com/2013/09/27/final-switch-goldsboro-1961/ … If fiss ~55%, 40+% from 14 MeV U238 FF in pusher, not so much from HEU 2/2 @NuclearAnthro @poloniumman

      @wheelcritter @NuclearAnthro @poloniumman My memory is that I read somewhere that it had an HEU sparkplug, but now I can't recall where.

      @wellerstein Isn't it safe to assume that all thermonuclear weapons have sparkplugs, or at least used to have them at the time?

      @pfc_joker The question is not whether it had a sparkplug (which I think is safe to assume) but whether it was HEU or Pu.
