Abstract
We have proposed a new nondestructive assay system for 239Pu and other actinides in spent nuclear fuel assembly in a water pool. Nuclear fuel materials are detected using nuclear resonance fluorescence(NRF) with laser Compton scatter (LCS) gamma-rays, which are generated by collision of high energy electrons and laser photons. For the study of this method, we have extended a particle (photon) transport simulation code GEANT4 to calculate NRF. We have demonstrated NRF events. To compare with calculated results we have carried out a nuclear experiment using the LCS gamma-ray at AIST.
