Recent development in the quality control of nuclear materials with respect to bulk determination

Chemical quality control of nuclear fuels is essential for smooth operation of nuclear reactors. Thus very accurate and precise measurement of U and Pu content in nuclear fuel is must in order to get the desired performance of the fuel inside the reactor. A large number of destructive and non-destructive analytical techniques are available for (U, Pu) determination, but redox titrimetric methods offer several advantages over other techniques if cost, time, precision, accuracy, space, analyst's effort etc are all together taken into account. This talk will give a brief report on development of simple cyclic voltammetry techniques for simultaneous determination of U and Pu in FBTR and PFBR fuels with PEDOT:PSS modified glassy carbon electrode. This method shows accuracy and precision as comparable to those of the biamperometry method. High robustness, fast analysis, simultaneous determination, reduced radiation exposure to the analyst, and ease of recovery of U and Pu from analytical waste makes it a suitable candidate to substitute the presently applied biamperometry method
