1) In the first stages a beam of extremely hot PROT is sent out. 2) A powerful vacuum is created where LAVA and PLUT are accumulated in the center. 3) Approximately 5 seconds after the initial implosion, pressure is equalized and LAVA and PLUT start falling back down onto the impacted area. 4) In the last stages PLUT is ultimately compressed and heated (usually by LAVA and its own weight) to the point where fission takes place. 5) A significant secondary explosion may result from that process.
Composition :The core is PROT (at 22C) Next layer is DEUT (cooled at - 175C) TTAN is the third layer (at - 175C) Fourth layer is PLUT at 26CExternal layer is IRON at 22C
