Shock ignition (SI) is one of the attractive topics for inertial confinement fusion (ICF). This two-step ICF process separates fuel assembly and ignition, relaxing the driver requirements and promising high gains. One of the main concerns about current working on nuclear power Reactor is the potential hazards of their radioactive waste. In the design of future fusion power plants, there still exist radiological hazards due to accumulation of byproduct tritium in blanket layer and also collisions between 14.1MeV neutrons released from Deuterium- Tritium(DT) fusion reaction and nearly all fusion reactor building materials. Therefore, in this paper, ignition requirements and fuel gain of non-equimolar DT fuel pellet have been studied in SI scheme. Our calculations show that the hot-spots formation conditions depend on densities of hot-spot and its surrounding cold fuel. Finally, the role of physical parameters on energy gain is investigated, including fuel mass, the ratio of hot- spot pressure to cold fuel pressure, different tritium weight fractions and isentrope parameter.
