BIE Ye-wang'-,ZHANG Dong-hui',CHEN Xiao-liang',FAN Zhen-dong',YANG Yong(1. China Institute of Atomic Energy,Beijing 102413,China;2. Nuclear and Radiation Safety Centre, Beijing 100082, China) Abstract: It is necessary to identify the failed fuel assembly after fuel failure occurred, which ensures safe operations of reactor and immediate treatment of failed fuel rod. The paper gives an extensive study on fuel failure location methods in sodium cooled fast reactor, and summarizes location principles, characteristics, applied ranges and disadvantages for each location method. On this basis, the thesis gives a prospect of the R&D on fuel failure location technology for the sodium-cooled fast reactor. This study may act as a valuable reference for selection and design on the fuel failure location system of Chinese fast reactor.
