ADS Transmutation Coolant Select Heap And Simulation Of Systems With Temperature Feedback

Accelerator-driven subcritical system( ADS) is the most powerful tool for transmutation of nuclear waste, a proton induced spallation reactions can produce dozens of neutrons, so that sub-critical systems to maintain a chain reaction in order to obtain and use the extra energy neutron transmutation proliferation of nuclear materials and nuclear waste, the lack of such treatment international nuclear fuel sector approach is considered to be a promising new generation of nuclear energy technology route, the research results will significantly improve energy system efficiency and environmental resources benefits. This paper studies abroad ADS transmutation reactor, as well as literature studies Monte Carlo method, by using ORIGEN2.1 and MCNP5 software, research ADS system coolant choice, the accumulation of minor actinide and long-lived fission products found in the study of three kinds of coolant liquid greatest impact on the overall lead, while the minimum liquid sodium impact; 99 Tc obtained by ADS greater impact on the neutron energy spectrum, and 129 I of the neutron spectrum shadow; Evolution Simulink software through the stack on the reactivity of the research done, the reactor was found in the external case of the introduction of the reactive power is stabilized at another power level. Introduced by the negative effect of temperature reactive, so that the reactor has a selfstability. The conclusion provides a reference for future studies of ADS.
