Summary: A fast and accurate method for predicting hydrogen solubility and trapping in alloys is presented, which is much faster than conventional approaches. The method is validated by studying hydrogen redistribution in nuclear fuel cladding. The results show that hydrogen solubility and redistribution are influenced by alloy composition and irradiation.

Summary: This study found that increasing dissolved oxygen in water enhances the production of oxidizing species, while increasing pH decreases the oxidative capacity of the UV/VUV/I- process. The treatability of the UV/VUV/I- process depends on the pH value, with better performance observed at pH 11.0 and below.

Summary: The addition of graphite nanoplatelets (GNPs) improved the density, compressive, and flexural strength of mortar, with high aspect ratio GNPs showing the best mechanical properties. However, the use of low aspect ratio GNPs resulted in decreased electrical resistivity and increased thermal conductivity in cementitious nanocomposites.

Summary: The study investigates the grain growth of nanocrystalline AlxCoCrFeNi high-entropy alloys with varying Al content under ion irradiation. It shows that the grain size increases with Al content and irradiation dose, with the highest growth rate observed for the Al-2 alloy due to its lowest cohesive energy. The grain growth mechanism is attributed to disorder-driven and defect-driven processes under ion irradiation, demonstrating the possibility to control grain sizes for nanostructured materials in nuclear applications.

Summary: The research shows that increased consumption of bioenergy leads to higher mortality rates in both developed and underdeveloped countries in the European Union. It is necessary to critically evaluate the production life cycle of bioenergy and strengthen production procedures in the bioenergy industry. Additionally, there is a need to intensify promotion and usage of bioenergy products, especially in rural areas in developed EU countries.

Summary: Hydrogen diffusion studies in Zr-2.5% Nb alloy pressure tube material are important for modeling localized embrittlement phenomenon. The microstructure of the pressure tube consists of lamellar alpha-Zr and beta-phase with stingers and globules. The diffusivity values for hydrogen in Zr-2.5%Nb alloy along different pressure tube directions were studied, and correlation with the microstructure was analyzed. Neutron radiography was used to study diffusion along different directions, and a theoretical approach was followed for evaluating diffusivity values for the alpha-Zr and beta-Zr phases.

Summary: Envenomations from animal bites and stings are a significant public health issue. While there is no standardized protocol, parenteral administration of polyclonal antivenoms is the main treatment for snakebites. It is believed that intramuscular administration is not very effective, and intravenous administration is preferred for better therapeutic activity. Recent research has shown that neutralization in the lymphatic system also plays a role in clinical outcomes, as it is another route through which venom is absorbed.

Summary: This study investigates the effects of microwaves on plasma emission intensity between Zr metal and Zr oxide using microwave-enhanced laser-induced breakdown spectroscopy (MWE-LIBS) for analyzing nuclear fuel debris mixtures. The results show that microwaves can enhance Zr excitation and ionization in both metals and oxides. The use of MWE-LIBS significantly increases Zr emission lines, leading to a higher signal-to-noise ratio (SNR) across all sample types. This study highlights the effectiveness of MWE-LIBS in analyzing Zr metals and oxides in nuclear fuel debris.

Summary: By combining first-principles calculations with statistical physics tools, this study investigates carbon diffusion mechanisms and coefficients in pure-Fe and weakly alloyed M3C cementites. The results show good agreement between predicted coefficients in Fe3C and experimental measurements of carburization rate in ferritic steels. Additionally, the presence of Mn solutes in alloyed cementites can slow down carbon diffusion up to 500 K, while the addition of Mo or Cr solutes has minimal effect on carbon diffusion.

Summary: Additive manufacturing (AM) is a promising technology for designing materials with complex geometries, reducing cost and waste. This study compares the radiation resistance of AM materials with conventionally processed materials in the nuclear industry. The results show that cavities are mainly located near grain boundaries in different alloys. Only the AM material after heat treatment has intra-granular cavities, which may have existed before irradiation. No intra-granular cavities are found in the conventional material or the AM material after hot isostatic pressing (HIP). The AM material with a hot treatment at 700℃ has heterogeneously distributed loops due to a bimodal distribution of grains, and the loop density is reduced by intra-granular misorientation after irradiation. The size of cavities and the dislocation network suggest a slightly reduced radiation swelling resistance for the AM material, but further investigations are needed at higher irradiation doses.

Summary: This study investigates the influence of He-V complexes on H behaviors on different W surfaces using DFT calculations. The results show that H dissolution is most difficult but H trapping is easiest on the W (110) surface, while the opposite is true on the W (111) surface. Moreover, the presence of He-V complexes increases the difficulty of H diffusion from bulk to surface and desorption.

Summary: The characteristics of magnetron sputtered Cr coatings vary with different temperature, bias voltage, and pressure. Coatings with random orientation, good crystallinity, and small grain size exhibit favorable oxidation behavior, while coatings with strong (200) texture, poor crystallinity, and large grains have many intrinsic defects that are detrimental to the protection property of the Cr coatings.

Summary: This study discusses the effects of ZrO2 and B2O3 on the phase composition and properties of SAP-based glass-ceramics. The results show that ZrO2 addition improves the formation of NZP phase while restricting the crystallization of AlPO4 phases. The correct ratios of ZrO2 and B2O3 allow only the formation of NZP phase within the SAP glass.

Summary: This paper investigates the oxidation and shape evolution of matrix graphite in high temperature gas-cooled reactors during air-ingress accidents. A reaction kinetics model is established and computational fluid dynamics with a dynamic mesh method is used to simulate the oxidation process. The results show that the geometric shape of graphite changes significantly with increasing flow rate, and the graphite pebbles tend to form a structure with a narrow front and wide tail.

Summary: This study proposes a probabilistic and diffusion-based model to describe the co-deposition of multiple hydrogen isotopes with slowly grown metal layers. The model calculates the relative concentrations of different hydrogen isotopes in the co-deposited metal layers. It is found that if hydrogen isotopes have different detrapping energies, only the isotope with the highest detrapping energy shows a monotonic decrease in concentration with deposition temperature. Furthermore, the study evaluates the uncertainty of tritium concentration in the co-deposited layer based on the uncertainty in detrapping energy of tritium and deuterium, predicting a >10% tritium concentration uncertainty for a 0.01 eV difference.
