Title:
ウラニウム酸化物に含まれたランタノイド系列元素の含有量を測定する方法
Document Type and Number:
Japanese Patent JP3552218
Kind Code:
B2
Abstract:
The present invention relates to a method for measuring the content of Lanthanides dissolved in uranium oxide, wherein the Lanthanides content in the nuclear fuel pellet is measured using the thermo gravimetric analysis which measures the weight variation caused by the oxidation and heat treatment of the nuclear fuel pellet. This method provides an advantage in that the Lanthanide content can be measured using relatively simple equipments such as an electric furnace and a balance.
