文摘

Dissolution of metallic alloys, U–Zr and U–Pu–Zr has been investigated in HNOb>3b> media. An electro oxidative dissolution technique was also examined. Explosive nature of metallic alloys during dissolution in nitric acid has been investigated. A method has been developed for the determination of zirconium in the presence of uranium and plutonium using a spectrophotometric technique. The influence of HNOb>3b>, uranium and plutonium during the estimation of Zr has been studied. Plutonium interferes in the estimation of Zr and it can be avoided by employing ascorbic acid. The method was employed for the estimation of Zr in samples generated during dissolution of Zr containing alloy fuels.
