Nuclear Energy: Principles, Practices, and Prospects

Accumulation of radioactive corrosion products on steel surfaces of VVER type nuclear reactors. I. 110mAg

The increasing popularity of nuclear energy necessitates development of new methods to treat water that becomes contaminated with radioactive substances. Because this polluted water comprises several dissolved species (not all of which are radioactive), selective accumulation of the radionuclides is desirable to minimize the volume of nuclear waste and to facilitate its containment or disposal. In this article, we use shock electrodialysis to selectively, continuously, and efficiently remove cobalt and cesium from a feed of dissolved lithium, cobalt, cesium, and boric acid. This formulation models the contaminated water commonly found in light-water reactors and in other nuclear processes. In a three-pass process, a consistent trade-off is observed between the recovery of decontaminated water and the percentage of cobalt removed, which offers flexibility in operating the system. For example, 99.5% of cobalt can be removed with a water recovery of 43%, but up to 66% of the water can be recovered if deionization of cobalt is allowed to drop to 98.3%. In general, the energy consumed during this process (ranging between 1.76 and 4.8 kW h m-3) is low because only charged species are targeted and virtually no energy is expended removing boric acid, the most abundant species in solution.

Adsorption and immobilization of radioactive ionic-corrosion-products using magnetic hydroxyapatite and cold-sintering for nuclear waste management applications

A detailed study of the reliability of some crucial parameters used in the in-situ radiotracer sorption studies

The entire array of charged species and oriented dipoles existing at the electrode/electrolyte interface, i.e., the structure of the electrical double layer, can have predominant effects on electrode processes. Several, now classic, books (see e.g., Refs. 1–3) have presented a description and analysis of the structure of the electrical double layer, emphasizing the central role of two types of adsorption (such as specific and nonspecific) in the understanding and mechanistic interpretation of various interfacial phenomena. Owing to the potential relevance of this field, comprehensive investigations of the sorption processes occurring at electrode/electrolyte (especially at metal/solution) heterogeneous systems have comprised a substantial part of electrochemical studies for many decades. Extended fundamental and applied research has been carried out on various, more or less closely related topics. In addition to an examination of the adsorption, electrosorption, electrocata-lytic, etc., behavior of different metal (mainly noble metal) electrodes, studies into the kinetics and mechanisms of corrosion, corrosion inhibition, and radioactive contamination processes on metallic constructional materials of industrial importance have also entered the spotlight of scientific interest (see Refs. 3–8 and references cited therein).
