Based on the analysis of energy structure and the development trends of advanced nuclear energy technology, combining the complementary advantages of nuclear energy and other energy sources in China, the Fluoride-salt-cooled High-temperature Reactor(FuSTAR) system has been proposed. FuSTAR system is designed to address production capacity issues in areas with energy shortages or resource concentration and can be combined with high-temperature process heat to achieve high-value-added processes such as hydrogen production. In this paper, the design and optimization processes of FuSTAR are described from three aspects: the neutronic and thermal-hydraulic system, the thermal transport system, and the power cycle system. Tri-structural isotropic fuel combined with helical cruciform elements has been studied in detail on the neutron physics and thermal-hydraulic properties, and the flow and heat transfer experiment is carried out for the first time. The multilayer nonlinear programming method has been applied to the design of thermal transport systems and the passive residual heat removal system and proved to be fast and efficient. Then the optimal parameters and configuration of the thermoelectric conversion system are obtained directly by using the superstructure optimization method, which saves computing resources greatly. Based on the above design and parameters, the inherent safety of FuSTAR is demonstrated through deterministic safety analysis. In addition, the iodine-sulfur cycle technology is also designed and analyzed, and the characteristics of tritium production in FuSTAR are calculated. The research provides important guidance for the detailed design and operation of FuSTAR. Moreover, this study highlights the significant potential of integrating nuclear energy with other energy sources in an optimized energy-production system. Based on the current research findings, prospects for future research directions are also suggested. © 2023, The Authors. All rights r

To get more acknowledges about W-shaped flame boiler, scaled down experiment system was set up to collect the basic data about temperature, strain, stress, shear and heat flux distribution of W-shaped flame boiler. The results showed that temperature distribution is mainly decided by the distance of the flame. Area which is washed against by flame shows high temperature. The temperature on the front wall is higher than rear wall, especially on the connection zone between furnace chamber and upper ash hopper. Heat flux distribution is dominated by both radiation and convective heat transfer. High heat flux zone is surrounding the burners and it is decided by temperature in furnace chamber. Medium heat flux zone is along the route of the gas fume and it is decided by gas fume's convective heat transfer. Strain distribution is well matched with temperature distribution especially in high strain zone. And the magnitude of stress depends on temperature gap, but the direction depends on both temperature gap and external constraints. In this experiment, we find that front wall is more vulnerable than other walls especially on the connection zone between furnace chamber and upper ash hopper. It is of high value on boiler safety operating and on optimization of the furnace chamber's structure. © ICOPE 2019 - 7th International Conference on power engineering, Proceedings.

The gradient-doping technique has been widely applied to induce an oriented built-in electric-field. However, it is still not efficient enough for charge mobility especially for particulate semiconductors, as the field is primarily in one direction from inner to surface. Here, we propose a multilocal gradient-doping technique that a nano-capsule is designed to store dopants and then release them into semiconductors nonuniformly. As an illustration, scattered pyrochlore-type K2Ta2O6 nanoparticles have been validated the capability of storing and releasing K+, which subsequently diffuse into the substrate PCN. Multi point-radiative gradient in K+ concentration, confined within the K2Ta2O6’s vicinity, will construct several 3D potential wells which can not only accelerate the carrier separation but also offer more migration channels for both photo-induced electrons and holes to the surface. Consequently, the multilocal K+ gradient-doping PCN shows the longest carriers’ lifetime and highest AQY (~21.8% at 400 nm) compared with the other uniformly doping techniques. © 2023, The Authors.

Photocatalytic water splitting for hydrogen production is more sustainable than traditional desalination and electrocatalysis, because of avoiding electrode corrosion and other problems. Two-dimensional perovskite oxide materials have multiple characteristics such as ferroelectric, piezoelectric and pyroelectric properties, demonstrating good light response and chemical stability, which provides a broad prospect in photo-chemical conversion. In this study, acidified La2NiO4 can greatly improve the amount of hydrogen evolution by coupling its piezocatalysis and photocatalysis. Under the full-spectrum illumination assisted with ultrasonic vibration in seawater, a recordable hydrogen production activity of 1315.44 μmol·g-1·h-1 was obtained in acidified La2NiO4 by 0.006 mol/L HCl, which more than 200 times higher than that of pure La2NiO4 (6.89 μmol·g-1·h-1) in methanol solution. It is found that the significant hydrogen production of La2NiO4 samples treated with acidification lies in the fast separation of charge carriers in comparison with those without acidification. © 2022, The Authors.

The coupling factor is used in this study to characterise the combined effect of the heat transfer and resistance characteristics of a rifled tube. Boundary layer theory is utilised to investigate the relationship between the comprehensive coefficient and Reynolds number in two regions, namely, higher and lower than pseudo-critical enthalpy. Results indicate that mass flux exerts a decisive negative influence on the coupling effect, and the impacts of pressure and heat flux are weak. The overall effect decreases rapidly as the mass flux increases, but it increases in the area behind the quasi-critical enthalpy. The coupling effect is also affected by specific heat ratio, thermal acceleration and buoyancy. The correlations of heat transfer and friction resistance are deduced with high precision according to experimental data.
