| Abstract: | Materials and methods of synthesizing mixed-layered bismuth oxy-iodine
materials, which can be synthesized in the presence of aqueous
radioactive iodine species found in caustic solutions (e.g. NaOH or KOH).
This technology provides a one-step process for both iodine sequestration
and storage from nuclear fuel cycles. It results in materials that will
be durable for repository conditions much like those found in Waste
Isolation Pilot Plant (WIPP) and estimated for Yucca Mountain (YMP). By
controlled reactant concentrations, optimized compositions of these
mixed-layered bismuth oxy-iodine inorganic materials are produced that
have both a high iodine weight percentage and a low solubility in
groundwater environments. |
