This study is to survey the feasibility of passive non-destructive assays (NDA) techniques of molten fuel material for their waste classification system. LaBr₃ (Ce) detector is chosen and the detector response is evaluated by The Particle and Heavy Ion Transport code System (PHITS) 2.82 code simulation. The Minimum Detectable Activity (MDA) of ¹⁵⁴Eu is determined and indirectly obtained alpha emitter density by performance evaluation for waste classification.
