<p>One of the most important affairs in the nuclear industry is the fuel cycle situation prediction. It affects the energy company’s profit, environment and even the safety of reactor operation. For these reasons, a series of computer codes have been generated to simulate the fuel cycle scenario including NFCSim, ORION and so on. At the Department of Reactor Physics, a new fuel cycle simulation code is under development and this code will be used in the present thesis.In order to simulate the nuclides transmutation chains, MCNP was first used to calculate the neutron spectrum and cross section data for the reactor cores, using JEF 3.0 and EAF 99 data libraries.The main task of this project is to simulate the present and future status of all the facilities in Chinese reactor park. Three consecutive scenarios (present, near-term and long-term) are defined for this comparison, simulation time scale is set to be 208 years (1992~2200) and four groups of nuclides (major actinides, minor actinides, major fission products and safety related nuclides) are defined and presented.Power balance scenario, plutonium self-sustained scenario and CIAE proposals are discussed individually as choices of reactor parks’ future development. The result is that at least 70 years (cooling storage time is not included) are needed to transmute the minor actinides inventory after the large-scale FBR (Fast Breeder Reactor) technology is mature enough for large scale commissioning in plutonium-sustained scenario.</p>
