Summary: Mag@silica-Ag composite has high sorption ability for I- in aqueous solution due to its high surface area and affinity, quickly reaching equilibrium. It selectively removes I- from mixtures and follows Langmuir isotherm and pseudo-second-order kinetics, with a maximum adsorption capacity of 0.82 mmol/g. This study demonstrates a practical use of high-capacity adsorbent for removing radioactive I- from wastewaters.

Summary: This study investigates the performance of B2O3-Bi2O3-ZnO low-temperature glass-ceramics for immobilizing iodine-loaded silver-coated silica-gel. The results show that the sample with 20 wt% iodine presents optimal immobilization at 600 degrees C. SEM-EDS results indicate two approaches contributing to the immobilization of AgIs. The TGA-DSC analysis shows high water content in the samples, facilitating the curing of iodine at low temperatures.

Summary: This study develops a method using amyloid fibrils derived from food proteins as solid adsorbents for direct capture of CO2 from the air. The results show that the CO2 sorption properties of the adsorbents depend on the mixing ratio of aminosilane and the type of amyloid fibril. Beta-lactoglobulin fibril-templated aerogels exhibit the highest CO2 adsorption capacity.

Summary: Silica aerogels were functionalized with polydopamine (PDA) using an in situ coating method, resulting in aerogels with enhanced optical absorption. The use of a siloxane precursor with an amine functionality allows for superior PDA coating. The in situ PDA coating method does not affect the inherent properties of silica aerogels and shows potential for UV protection applications.

Summary: Silver phosphate glasses were studied for conditioning of radioactive iodine 129, with Nb2O5 and Bi2O3 as crosslinking agents. The impact of these modifications on glass chemical durability, especially the addition of Nb2O5, was significant in reducing phosphorus release rates and forming a passivating layer in long-term alteration tests. The results suggest that elemental release in solution alone may underestimate alteration rates, emphasizing the importance of considering different elements in glass composition.

Summary: This study evaluated the adsorption of gaseous iodine [I-2(g)] on five different metal coupons under controlled conditions. Humidity was found to play a critical role in iodine adsorption on SS304, SS316, and Ni-200 at ambient temperatures. The results showed that a moisture-mediated reaction is occurring and higher humidity levels decrease adsorption. The comparison of the metal substrates showed that Ni-200 had the highest adsorption, followed by SS304, SS316, 718, and 625. The findings provide insights into predicting iodine adsorption behaviors on various metal surfaces under near-ambient conditions.

Summary: In this study, the volatility of sodium, potassium, and cesium perrhenates was investigated using thermogravimetry. The results showed that the order of volatility of alkali perrhenates is CsReO4 > KReO4 > NaReO4. This differs from the observation from Hanford LAW glass feeds, suggesting that the volatility of the perrhenates may be dependent on the composition of the salt.

Summary: This study investigated the melting behavior, glass transition temperature, oxidation state, network structure, and chemical durability of 1500-year-old vitrified hillfort glasses. The results showed that the oxidation state of iron affected the network connectivity of the glass-forming melt, but it did not affect the chemical durability of the final glass. Glasses with lower network connectivity had lower viscosity and transition temperature.

Summary: This research investigates the influence of P2O5 additions on the properties and structure of SiO2-B2O3-Na2O glasses used for radioactive waste immobilization. The study reveals that the addition of P2O5 leads to changes in viscosity, glass transition temperature, and crystallization behavior. X-ray diffraction analysis confirms the presence of crystalline phases at specific P2O5 concentrations. The findings highlight the importance of P2O5 content in controlling the properties and structure of the glasses. Overall, this research provides valuable insights for the development of effective waste immobilization materials.

Summary: The speciation and solubility of technetium during nuclear waste vitrification are influenced by the oxygen partial pressure in the melt. Sucrose, a reducing agent commonly added to nuclear waste feeds, can significantly impact the volatilization of technetium and enhance its retention in glass. This study measured the retention of a surrogate element, rhenium, and observed that increasing sucrose content improved rhenium retention without reducing iron redox.

Summary: The study investigated the alteration of archaeological glasses to understand glass durability for the disposal of nuclear waste. Glasses from Broborg hillfort in Sweden, formed from melting amphibolitic and granitoid rocks, were analyzed using microscopic, spectroscopic, and diffraction techniques. The felsic glass had a uniform chemistry and smooth surface with limited alteration, while the mafic glass had a heterogeneous surface with roughness and evidence of microbial colonization on topsoil-exposed surfaces.

Summary: Foaming during vitrification of radioactive waste in JHCM is caused by trapped gases beneath a viscous reaction layer. Sucrose is commonly used to reduce foaming, but alternative carbon-based additives like graphite and coke were found to be more effective. These additives not only reduced foam volume, but also affected the behavior of multivalent species in glass melts under different redox conditions. The results provide insights for more efficient vitrification processes in JHCMs.

Summary: The glass transition temperature (T-g) of low-activity waste (LAW) glasses was measured using differential scanning calorimetry and combined with T-g data from literature. Several models were developed to estimate T-g from glass composition, and it was found that using more than 10 components or non-linear methods did not significantly improve the model accuracy. The best model accurately predicts T-g for both LAW and high-level waste glasses.

Summary: The performance of refractory lining in nuclear waste glass melters is crucial for reliable long-term operation. Monofrax® K-3, a high Cr2O3 fused cast refractory material, is commonly used in the United States. However, there is limited corrosion data under actual melter operating conditions, and recommendations are made to improve the correlation between laboratory corrosion data and observed melter service life for more accurate predictions.
