Good afternoon! welcome back to war! another week starting! So, let's start to be serious, and not Chechnya type of guys in Moscow :) Ok, we get 3/4 kg of unprocessed uranium, for a 1/3 of High enriched , the fissile material, called critical mass, will spontaneous react, on a big bang! BUT! there's a very important part the bomb! the neutron initiator! this are pictures, how to build a nuclear initiator, absolutely necessary for the blast to occur! As you know, if I already have the tritium..." Very small quantities of deuterium or tritium are necessary and they are found in a small high-pressure sphere at the center of the fissile core. The tritium in a DT initiator is radioactive and has a half-life of approximately 12 years. "
