The management of radioiodine and prevention of its release to the environment is paramount in the nuclear industry. This includes release of radioiodine during used nuclear fuel reprocessing or other nuclear technology, the release during nuclear accidents and in the management of legacy wastes. This collection of articles will assess novel methods for capturing and immobilizing radioiodine, present methods for observing and characterizing iodine gas streams, and discuss the future of this topic area. While porous zeolite-type sorbents have been the primary focus of study for solid sorbents in the past, a long list of new sorbents have been presented in recent years that show promise. Other types of remediation approaches have been evaluated recently as well that will be discussed along with addressing the challenges with the long-term disposal of radioiodine.
The goals of this Research Topic are (1) to push the boundaries of radioiodine capture and detection technologies towards higher efficiencies and higher technology readiness levels, (2) to develop and present new methods of immobilizing radioiodine for safe storage in a long-term repository, and (3) to develop cheaper and greener alternatives to using silver-based sorbents.
We welcome the submission of Original Research articles, Reviews, Mini-Reviews and Perspectives on the themes that include, but are not limited to:
• New and novel iodine capture processes including remediation of gaseous species (e.g., I2, CH3I, ICl) and/or aqueous species (e.g., I-, IO3-) to prevent the release of radioiodine into the environment as a sorbent or final waste form
• Fundamental science approaches to finding the next-generation sorbents and understanding the mechanisms of durability in the final disposal forms.
• Methods for detecting iodine gas species are also desired for measuring speciation (i.e., identifying the forms of iodine present) as well as quantification
• Approaches to integrating the design of the capture material with its subsequent conversion into a wasteform
