| Popis: | The safe handling of reprocessed fuel addresses several scientific goals, especially when considering the capture and long-term storage of volatile radionuclides that are necessary during this process. Despite not being a major component of the off-gas, radioiodine (I2) is particularly challenging, because it is a highly mobile gas and 129I is a long-lived radionuclide (1.57 × 107 years). Therefore, its capture and sequestration is of great interest on a societal level. Herein, we explore novel routes toward the effective capture and storage of iodine. In particular, we report on the novel use of a new class of porous solid-state functional materials (metal–organic frameworks, MOFs), as high-capacity adsorbents of molecular iodine. We further describe the formation of novel glass-composite material (GCM) waste forms from the mixing and sintering of the I2-containing MOFs with Bi–Zn–O low-temperature sintering glasses and silver metal flakes. Our findings indicate that, upon sintering, a uniform monolith i... |
