Cfd Study on Coolant Mixing in Vver-440 Fuel Rod Bundles and Fuel Assembly Heads
A CFD model of VVER-440 fuel assembly heads was developed based on the technical documentation of a full-scale test facility built in the Kurchatov Institute, Moscow. Steady-state and transient calculations were performed to validate the model with a measurement set and investigate the effects of the spatial discretization, choosing of different turbulence models and use of different inlet boun...
متن کاملComparison of n-type Gd(2)O(3) and Gd-doped HfO(2).
Gd(2)O(3) and Gd-doped HfO(2) films were deposited on p-type silicon substrates in a reducing atmosphere. Gd 4f photoexcitation peaks at roughly 7 and 5 eV below the valence band maximum have been identified using the resonant photoemission of Gd(2)O(3) and Gd-doped HfO(2) films, respectively. In the case of Gd(2)O(3), strong hybridization with the O 2p band is demonstrated, and there is eviden...

The Spent Fuel Assemblies (SFAs) of WWER-1000 reactors are planned to be transported by special containers which are supposed to be designed in a manner to stand against vibrations and impacts in order to protect the spent fuel from any possible damage. The vibration opposition of these containers shall be far beyond the critical resonance, because the resonances about the natural frequency of ...
متن کاملStudy on the effect of using reformed biogas as a low reactivity fuel in a dual-fuel engine (RCCI)
The scarceness of non-renewable energies, rising fossil fuels prices, as well as strict environmental regulations have forced many researchers to focus on utilizing environmentally friendly renewable energies such as biogas in internal combustion engines. Variety in raw materials and process of biogas production results in different components and percentages of various elements, including meth...
