Neutron resonance densitometry with a self-indication method is currently under research to quantify nuclear material in the debris of melted fuel. In this work, we have developed new method to identify the nuclear material using a stationary neutron source. Moreover, we tried to apply the self-indication method to neutron imaging. We report the possibility of non-destructive neutron imaging of nuclear materials using a stationary neutron source based on experimental and numerical calculation results.
