... corrosion resistance and mechanical properties at operating temperature. During the operation of zirconium alloy cladding, corrosion resistance is a critical life-limiting degradation mechanism, temperature and lithium concentration are the key factors for corrosion resistance. In order to study the effects...

... of pipe wall, which will adversely affect the safe operation of the reactor. The law of fine particle deposition on the outer wall of the simplified heat pipe model was numerically simulated, and the particle deposition in the fluid field outside the pipe was obtained under different temperature...

...-temperature potassium heat pipe, and to investigate the effects of the horizontal acceleration, inclination angle and saturation temperature of the mass inside the heat pipe on the overall heat transfer performance of the heat pipe. It is found that the heat transfer performance of the heat pipe increases...

...-temperature, high-pressure, high-irradiation environment of a nuclear reactor, the non-condensable gas produced by the lithium heat pipe - helium - affects the heat transfer efficiency of the heat pipe. Therefore, by modeling the heat transfer process of the heat pipe, the effect of the content of the non...

... operation of the reactor. The grey correlation analysis method is used to calculate and analyze the particulate matter concentration distribution at different heights of the supercritical water reactor coolant channel model. The correlation of coolant temperature, axial velocity and turbulent kinetic energy...

... temperature mechanical properties. Irradiation can easily lead to the degradation behaviors of materials, such as irradiation hardening, irradiation embrittlement and high-temperature He embrittlement, etc. Understanding such degradation is important for predicting the evolution of material behavior under...

... Abstract As the key component of RPV steel, α-Fe is under neutron irradiation during its long-term service, and lattice atoms of α-Fe are knocked by neutrons, which leads to irradiation damage. In this paper, molecular dynamics method is conducted to investigate the effect of temperature...

... Ultra-low concentration coal bed methane is difficult to utilize due to its low concentration and fluctuant flow. A laboratory fluidized bed reactor was employed to burn ultra-low concentration coal bed methane. The temperature and pressure characteristics during combustion were studied...

... Reinforced concrete structures for nuclear power plants are designed for thermal effects. When a structure is subject to transient temperature rise, the temperature distribution in a member becomes nonlinear. Commentary of ACI 349 code provides a method of converting a nonlinear temperature...

... CANDU-6 CFD Moderator Temperature A steady-state 3D simulation for predicting the local subcooling of the moderator in the vicinity of the calandria tubes in a CANDU-6 reactor is performed. For the current simulation, a set of grid structures with the same geometry as the CANDU-6...

... jets. As a result, the current CFD moderator analysis model predicts the moderator temperature reasonably, and the maximum error against the experimental data is kept at less than 2.0°C over the whole domain. The simulated velocity field matches with the visualization of SPEL experiments quite well...
