Abstract
Description
従来の方法の問題点を解決するために、本発明は、湿式再変換工程中の沈澱/濾過/乾燥工程で生成された重ウラン酸アンモニウム(ammonium diuranate)の色度を分光光度計(Spectrophotometer)で測定することにより、焼結体製造工程に投入される前にウラン酸化物(UOx)の焼結密度を分光光度計を用いて予測計算及び分析したが、このような方法は予測力に優れることを確認した。
ウラン酸化物(UOx)の前駆体である重ウラン酸アンモニウム(ammonium diuranate)粉末サンプルの色度値を分光光度計(Spectrophotometer)で測定してウラン酸化物(UOx)の焼結密度を予測計算及び分析するためには、まず標準データによるグラフを決定することが必要である。
実際のウラン酸化物(UOx)焼結体用粉末の製造工程運営中には、製造された重ウラン酸アンモニウム(ammonium diuranate)粉末のサンプルを採取してガラスセル(Glass cell)に適量投入した後、分光光度計(Spectrophotometer)でキャリブレーション(Calibration)を行って測定することにより、このような過程を介して色度値としてL*a*b*表色系を使用するデータを得る(図1のS100段階)。
