By integrating high-fidelity computational fluid dynamics (CFD) models with the MARS-LMR code, this research aims to validate predictive capabilities and assess reactor safety under severe accident conditions. The reliability of the MARS-LMR code in predicting thermal-hydraulic behavior for both steady and transient states was demonstrated. The code consistently provided conservative predictions compared to experimental data, ensuring robust safety margins. CFD simulations offered detailed insights into the reactor’s complex heat and flow dynamics, accurately capturing temperature distributions and flow patterns at various locations. Hot channel factors (HCF) were applied to evaluate the cladding temperature under maximum expected conditions. Results indicated that the peak cladding temperature, when considering HCF, remained below the safety limit of 1025°C, thereby ensuring a safety margin of 26%. Furthermore, CFD analysis underscored the importance of accounting for circumferential temperature variations in the cladding, emphasizing the necessity of HCF in comprehensive safety evaluations.

This study investigated the effects of various solvents on the electrospray of Ni-rich layered materials for electrode fabrication as an alternative to conventional slurry coating using the doctor-blade method. The electrode performance of a typical doctor blade method using the N-methyl-2-pyrrolidone (NMP) solvent, which has various disadvantages (boiling and autoignition temperature), was compared with that of electrosprayed cathodes using NMP; N,N-dimethylformamide (DMF); and DMF/acetone solvents. The volatility difference between the three solvents resulted in the creation of individual cathodes with different porosities. For the DMF/acetone solvent, which had the highest volatility, the coated cathode showed 75.97% capacity retention after 100 cycles at 1C, which was significantly higher than those of the NMP (62.91%) and DMF (66.25%) solvents. Electrochemical impedance spectroscopy (EIS) showed a stable peak retention during cycling and a low increase in individual resistance for the DMF/acetone solvent cathode.

One of the best and most promising sources of electricity is permanent rivers, which are spread throughout the country. Designing an optimal power system and minimizing installation costs requires a precise evaluation of flow rates and pressure heads. However, many of Ethiopia’s rivers, which are suitable for micro, mini, and small-scale hydropower plants, have not been sufficiently studied. Therefore, this article aims to evaluate the hydropower potential of the three most promising rivers (i.e., Chemoga, Huluka, and Wabe) located in the western region of the country, based on a 10-year daily flow rate history. Daily flow data were collected and converted into mean annual flow. The flow duration curve (FDC) was used to quantitatively characterize the variability of flow rates. Furthermore, QGIS was used to analyze the topographic information of the rivers. When the two critical parameters were determined, the respective hydropower potentials were determined. The result of the study shows that under high, moist, and mid-range flow conditions, the Chemoga River exhibits the highest theoretical hydropower potential, with power capacities of 4729.20, 3495.49, and 2133.08 kW, respectively. Alternatively, under low flow conditions, the Wabe River has the highest hydropower potential, with a theoretical output of 673.35 kW. In all cases, the power output of Huluka is significantly lower than others.

Meanwhile, the shrinkage pores are developed in the tuff-filled material of sand conglomerate reservoir, which is not only the oil/gas storage space, but also the ideal fluid flow channel of CO<sub>2</sub>. It is particularly important to select a reasonable pore throat cutting factor and accurately describe the structural and physical characteristics of the shrinkage pores for the evaluation of sand conglomerate reservoir. In this paper, the shrinkage pore developed sample is scanned with micro-computed tomography (CT) to obtain the 3D gray image. The shrinkage pore 3D digital rock is segmented, and the corresponding pore network model is extracted. Then, based on the 3D shrinkage pore network model, a different pore-throat cutting factor is selected to construct the shrinkage pore network models with different pore-throat spaces and calculate the physical/structural parameters. It can be found that, with the increase of pore-throat cutting factor, the number of pore-throat and porosity remain unchanged, and the permeability decreases, the pore volume distribution shifts to the left, the throat volume and throat length shifts to the right, and shape factor continuously shifted to the right. The increase of pore-throat cutting factor causes the interface between pore and throat to be more inclined to the pore side; the pore volume thus decreases, and the throat volume increases. Given the close agreement between laboratory-measured permeability (36.3 mD) and Lattice Boltzmann simulation results (38 mD) for the original shrinkage pore digital rock model, a pore-throat truncation factor of 0.3 ± 0.1 (range: 0.2–0.4) is validated for sandy conglomerate reservoir characterization. When <i>α</i> < 0.2, it causes overestimation of pore volumes and underestimation of flow resistance; when <i>α</i> > 0.4, it induces excessive throat length and misrepresents real pore-throat morphology.
