The systematic study on D 3He advanced fuel fusion in China has been performed. Comparisons between D 3He and D T fuel cycles in physics, engineering, environmental safety and so on have been made. D 3 He fusion offers significant advantages for reducing the neutron yield by a factor of 10 60. The 3He resource and mining possibility are investigated.The energy payback factor of 97 for mining lunar 3He resource is calculated.The operating parameter scope for D 3 He fueled Tokamak reactor is analyzed. The prompt energy broadening for fusion products is calculated and results are consistent with those obtained by Lehner using a different method. Centrally peaked current drive with high efficiency is studied utilizing plasma synchrotron radiation. More than 80% of plasma current required can be driven passively. A D 3 He fueled Tokamak commercial reactor Mooncity was designed. Neutronics calculations show that the radioactivity, afterheat, BHP value for Mooncity are 10～60 times less than those for D T fusion.
