摘要：
A physical scheme design of a 10 MW accelerator-driven sub-critical gas-cooled fast reactor was studied. The coupling program COUPLE2.0 was applied, which couples MCNPX and ORIGEN. The physical parameters such as keff, proton efficiency, accelerator current, power peak factor and Doppler coefficient of 1500 K varying with burnup time were obtained, and the safety feature of the system was analyzed. By further calculation the 350 d burnup of the system was obtained and the transmutation capability was analyzed. It is found that during the 350 d burnup, keff, accelerator current, power peak factor variations are relatively small. The system has good safety feature with deep sub-critical status in hypothetical accident. The total burnup is relatively shallow, but the system has good transmutation capability with the transmutation support ratio of 20.28.
