　　　Measurement of concentration of boron in stainless steel-boron carbide (SS-B₄C) alloy is in high demand for the decommissioning of the damaged nuclear reactor. In this study, quantitative determination of boron concentration in SS-B₄C alloy containing about 0.5 to 4mass% of boron was investigated by using inductively coupled plasma optical emission spectrometry (ICP-OES). The samples were dissolved completely with the combination of phosphoric-and-sulfuric-acids method and alkali-fusion method. Analytical line of 182.52 nm in wavelength was used to detect boron. The limit of quantification of boron in this method was 0.3 μg mL^-1. The analytical results were in good agreement with nominal values in high concentration sample. Boron in the sample having the concentration as low as 0.5-1 mass% can be successfully detected.
