Abstract
AbstractAccurate, precise, and rapid analytical monitoring of various nuclear materials is essential for the smooth functioning of nuclear reactors. Ion chromatography (IC) has emerged as an effective analytical tool for simultaneous detection of different ions in a wide range of materials used in the nuclear industry. The major advantages over other techniques include superior selectivity and sensitivity for detection of anions and cations, wide dynamic range, and speciation studies of ions. This article provides an overview of different ion chromatographic methodologies developed for the analyses of various nuclear materials such as fuel, control rods, moderator, coolant, and process streams. Comparison of various analytical aspects of IC over the other routine techniques reveals the ease and multidimensional capability of the technique. An insight is given to the modern variations in the field such as coupling of IC with other techniques for the characterization of nuclear matrices, implementation of capillary IC in terms of miniaturization, and so on. The information presented herein will serve as a very useful resource for investigators in the field of characterization of nuclear materials.

Ion chromatography (IC) has emerged as one of the reference methods for the analysis of different ions in water and wastewater samples, effluents from industries, airborne particles collected on particulate filters, and gaseous samples absorbed on charcoal [16]
Detection of trace impurities of borate, chloride, and fluoride in nuclear fuels is very important as boron can affect the neutron economy, and F− and Cl− at trace levels can corrode the clad surface by local depassivation of its surface oxide film, which eventually can lead to the clad failure
Summary
Abstract: Accurate, precise, and rapid analytical monitoring of various nuclear materials is essential for the smooth functioning of nuclear reactors. In the absence of the suppressor column, the analyte column is directly connected to the detector In this case, low-capacity resins in combination with relatively low-conductance eluents are employed for separation of ions of interest to manage the detector signal output, enabling sensitive detection of the sample components [9]. IC has emerged as one of the reference methods for the analysis of different ions in water and wastewater samples, effluents from industries, airborne particles collected on particulate filters, and gaseous samples absorbed on charcoal [16] Another important applications of IC is in power industries for the characterization of feed and process streams (retrieved from www.metrohm.com) [17]. To the best of our knowledge, this is the first review on ion chromatographic characterization of nuclear materials for the trace impurities
