Determination Of Oxygen To Metal Atomic Ratio In Mox By Nondispersive Infrared Spectrophotometry

The present method is based on the extraction gas analysis using nondispersive infrared spectrophotometry (NDIR) after inert gas fusion. The oxygen in the fused sample was quantitatively reacted with the carbon in a graphite crucible and the CO generated was determined using the NDIR. The relative standard deviation (RSD) was less than 0.20%, and the time required for one determination was about 10 min for all analytical operations. This method is applicable to sintered MOX fuels over a wide range of plutonium content.
