摘要

As one of the National Major Scientific and Technological infrastructures proposed in the“12th Five-Year Plan”,the“China Initiative Accelerator Driven System(CiADS)”will be constructed to further promote the development of ADS technology.For ADS,structural materials with good performances on the resistances to intense particle irradiation are important to determine the system’s feasibility and safety.In this work,radiation damage of several structural materials,such as 316L,SIMP steel,and ZTA ceramics were analyzed by using MCNPx Monte Carlo software coupling with NJOY 2016 code.The CiADS target-reactor model was established by MCNPx 2.70 code,and the neutron spatial energy spectra and neutron flux were calculated under three different core arrangement schemes.
