The investigations were conducted using the Serpent code and the JENDL-5 library. The results show that when fuel debris is surrounded by intact fuel assemblies, the k
can be classified into two groups based on the shape of the fuel debris. Conversely, in scenarios where the fuel debris is not fully encircled by intact fuel assemblies, the shape of the fuel debris has a negligible impact on the k. Additionally, the relationship between the number of neutrons entering and leaving the fuel debris determines how the shape of the fuel debris affects the k.

Times Cited Count：0 Percentile：0.00(K,Na)NbO (KNN)-based ceramics have been hesitant to be used in practical piezoelectric devices due to their poor chemical homogeneity, despite their excellent piezoelectric characteristics. In this study, we revealed that the role of NbO precursors varies depending on the processing approaches and is strongly correlated with the chemical homogeneity of KNN with the use of soft X-ray absorption spectroscopy. Therefore, the choice of NbO precursor is a dominant factor in the fabrication of KNN.

Here, we perform a study of the resistance of a Cantor alloy (CoCrFeNiMn) to hydrogen through high-pressure experiments at elevated temperatures by X-ray and neutron time-of-flight experiments and ab initio calculations. We report formation of an fcc hydride based on the Cantor alloy composition. We also provide its characterization, including an estimate of hydrogen content. These findings contribute to the growing body of knowledge on the complex chemistry of high-entropy alloys and high-entropy-hydrides.

The objective is to simplify the sample characterization process by developing multipurpose analysis tools that quickly produce results for different types of samples while reducing labor. The development of an analytical device has been started, based on the MiniPIX TPX standard detector, a hybrid semiconductor pixelated radiation detector. This detector creates grayscale images that show the interaction of ionizing particles, where brightness directly indicates energy. The final aim is to build a fast mapping device that generates 2D activity maps, distinguishing between , , and radiation, and includes simple local spectrometry for highly contaminated samples. The shape of the cluster created by the interaction between an incident particle and the semiconductor is typical of the said particle. Thus, eight supervised machine learning models have been trained on a dataset made of 9 features extracted from pure images of , and particles collected from 
Co, 
Sr, 
Cs and 
Am standard sources. The best models can distinguish the particles with nearly 80% accuracy, reaching 96% accuracy for low-energy rays exposition only, with a processing time of a few microseconds per frame. The identification of particles is 100% accurate.

Times Cited Count：2 Percentile：92.64(Multidisciplinary Sciences)Nanodosimetry, which is important for understanding the biological effects after ionizing radiation exposure, can be evaluated using Monte Carlo Track Structure (MCTS) codes that can reproduce atomic interactions at the molecular scale. Various MCTS codes, developed independently over decades, have used different physical models and cross section data sets for electron interactions in liquid water, that is the main component of biological tissues. In this study, we evaluated the uncertainties in nanodosimetric calculations due to the variation of interaction cross sections used in various MCTS codes. The calculation results of seven MCTS codes (i.e., Geant4-DNA, PARTRAC, PHITS, MCwater, and PTra) revealed that there were large differences in physical quantities at molecular scale, such as the average number of ionizations and the probability of two or more ionizations. The largest differences were observed for low-energy electrons, where the contribution of the interaction cross section was found to be the main cause of uncertainty. These results highlight that difference in the cross section have a non-negligible impact on biological effects, such as complex DNA damage induction.
