Abstract
PURPOSE:To enable exact measurement by determining the content of the oxygen in a nuclear fuel oxide and the content of the metal element to be measured by using a wavelength dispersion type fluorescent X-ray device, then converting these contents to a molar number and calculating the oxygen to metal atom number ratio. CONSTITUTION:A standard sample which has the same shape as the shape of an unknown sample of the object to be measured and into which the element to be measured is incorporated at stepwise concns. is previously prepd. and the calibration curve indicating the relation between the fluorescent X-ray intensity and content of this element is previously formed. The fluorescent X-ray intensity of the element to be measured is then measured with the unknown sample to be measured. The content (%) is thereafter determined by using the previously formed calibration curve from the fluorescent X-ray intensity of the element to be measured. This content is divided by the average atom weight of every element and the molar numbers of the respective elements are determined. O/M is then determined with the molar number of oxygen as numerator and the molar number of the metal element to be measured as denominator. The wavelength dispersion type fluorescent X-ray analysis apparatus equipped with a fixed spectroscope for measuring oxygen and the metal element to be measured is used as the measuring instrument. The form of the sample of the nuclear fuel oxide to be analyzed by the analysis apparatus is preferably a pellet shape molded under pressurization.
