Energy-recovery linac based laser Compton scattering (LCS) X/-ray sources have possibilities of various applications to non-destructive assay (NDA) in material accountancy and safeguards verification for future nuclear fuel cycle (FNFC) facilities with advantageous features of very high intensity, monochromaticy and tunability of energy. A LCS-X-ray source with energy of 110-130 keV could be applied to a fast hybrid K-edge densitometer, and a LCS--ray source with energy of 1-3 MeV to a NDA system of Pu (and actinide) in spent nuclear fuel and high-level active waste such as hull or vitrified waste by NRF (nuclear resonance fluorescence) method. The LCS--ray source with energy of 1-3 MeV could be applied to isotopic analysis of Pu etc. for solution, solid and powder samples after nuclear resonance cross section data of actinides is prepared. Also we present an idea of actual deployment of NDA systems using LCS-X/-ray sources in a hypothetical FNFC facility.
