The EAGLE experimental program is dedicated to show experimental evidences supporting a safety logic eliminating the recriticality issue in the core disruptive accidents (CDAs) of sodium-cooled fast breeder reactors. Two kinds of neutron detectors (one was placed in the test section and another was placed around IGR driver core for power monitoring use) were analyzed to get prospect that the data include information of molten-fuel motion in the in-pile test.
