Abstract: Based on the State Council 2012 “Nuclear Safety Plan (2011-2020)” and “Nuclear Medium and Long-term Development Plan(2011-2020)”, the report of “the research on China energy medium and long-term(2030, 2050) development strategy”of China Academy of Engineering Physics and “Chinese 13th Five-Year Plan ” combined the primary of operating M310 type reactors and the third generation HPR1000, AP1000, CAP1400, and the current and future PWR nuclear fuel cycle mode was studied under MATLAB simulation environment employing “once through” mode. The demand of natural uranium resource, separate works, the amount of spent fuel, plutonium, also minor actinides arising following the accumulative PWR nuclear reactors were calculated. Simulation result can be made as a reference for China fuel cycle development strategy, which speeds up to establish closed fuel cycle way.

Key words: nuclear fuel cycle, PWR, once-through fuel cycle, third generation reactor
