Laser-Compton-backscattered photons from an energy-recovery linac (ERL) and a high power laser realize a high-efficiency, high-flux and tunable monochromatic -ray source. A non-destructive interrogation method by using nuclear resonance fluorescence (NRF) make possible to measure the discrimination of clearance levels of a concrete solidification radioactive waste. The purpose of our work is to design and evaluation of the NRF-based detection system. For this evaluation, we are developing a GEANT4-based Monte Carlo simulation code. Some simulations have been performed with simple models of a concrete solidification radioactive waste cask and detectors. We present a recent result of the simulation.
