Abstract

Disclosed is a method of predicting, calculating, or analyzing the sintered density of uranium oxide (UO) before uranium oxide is added in the pelletizing process during a process of manufacturing nuclear fuel, the method including measuring the chromaticity of ammonium diuranate using a spectrophotometer. The present invention provides a simple and highly reliable method of predicting the sintered density of uranium oxide (UO), which overcomes the problem with a conventional technology where the sintered density of uranium oxide (UO) can be analyzed only in a pellet state and a subsequent treatment process needs to be performed according to the analysis result.
