If a deuterium-tritium mixture is placed at the center of the device to be compressed and heated by the fission explosion, a fission yield of 250 tons is sufficient to cause D-T fusion releasing high-energy fusion neutrons which will then fission much of the remaining fission fuel. This is known as a boosted fission weapon. If a fission device …
