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-³He 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-³He 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-³He 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.
