Ion accelerator based radiation simulations of neutron damage in reactors: issues and challenges in experiments and modeling   SHAO Lin 1   1. Department of Nuclear Engineering, Texas A&M University, College Station, TX 77843, USA (lshao@tamu.edu)   Abstract: Using accelerator-based ion bombardment as a surrogate irradiation source to simulate neutron damage in reactors is important to understand and predict materials degradation under extreme conditions. Challenges and issues, however, exist in both experimental and modeling studies. Major issues being discussed include (1) how to identity and understand neutron-atypical artifacts introduced in accelerator-based ion irradiations. Examples on defect imbalance and pulse beam effects are given; (2) how to standardize experimental procedures for ion irradiation testing. Examples on accelerator setups and beam control are given; (3) how to develop modeling capabilities to understand structural changes. Examples of Monte Carlo simulations, Kinetic Monte Carlo simulations and molecular dynamics simulations are given. Several methods to alleviate the issues are further discussed.  Keyword: radiation damage; accelerator; simulation
