Comparison of univariate and multivariate data analysis models for uranium quantification in Trombay historical nuclear waste glass

Autor: Manjeet Singh, C.P. Kaushik, Raman K. Mishra, Arnab Sarkar, P.G. Jaison, Amar Kumar

Publikováno v: Radiochimica Acta. 106:453-463

Laser induced breakdown spectroscopy recently has been investigated for analysis of nuclear waste glass for uranium quantification. The initial obtained accuracy and precision was ~15%. In this paper, we have compared the analytical merit of the univ

Effect on the structure and stability of iron phosphate glass with Sb and Te-ion loading for nuclear waste storage application

Autor: Akhilesh C. Joshi, C.P. Kaushik, Dimple P. Dutta, Mainak Roy, Rajath Alexander, Raman K. Mishra, Sher Singh Meena, Ravi Kumar, A. K. Tyagi, Debnath Bhattacharyya

Publikováno v: Journal of Non-Crystalline Solids. 570:121016

Iron phosphate glass (IPG) is emerging as an alternative to the more commonly used borosilicate glass for nuclear waste vitrification. Consequently, there is an urgent need to study the effect of loading of various elements generated as waste from nu
