Thermo-Hydraulic Investigation of Nanofluid as a Coolant in VVER-440 Fuel Rod Bundle [PDF]
Transport Phenomena in Nano and Micro Scales, 2015 The main purpose of this study is to perform numerical simulation of nanofluids as the coolant in VVER-440 fuel rod bundle. The fuel rod bundle contains 60 fuel rods with length of 960 mm and 4 spacer grids. In VVER-440 fuel rod bundle the coolant fluid (

Numerical Simulation and Validation of Flow-Induced Vibration of the Specific Rod under Elastic Supports using One-Way Fluid-Solid Interaction [PDF]
Journal of Applied Fluid Mechanics, 2023 The vibration induced by the cooling fluid flow around the fuel rods in the fuel Assembly of nuclear reactors causes the rods to be destroyed and eventually leak due to the fretting wear in the place of contact with their supports for a long time.

Defected fuel rods identification in TRIGA Reactors: The experience at the ENEA Casaccia TRIGA RC-1 reactor [PDF]
EPJ Web of Conferences, 2023 Experience in running TRIGA reactors all around the world has shown that fuel cladding failures can occur. Fission products, especially in gaseous physical form, can exit the defected fuel rods being dispersed within the water primary coolant.

Neutronic design and evaluation of the solid microencapsulated fuel in LWR
Nuclear Engineering and Technology, 2022 Solid Microencapsulated Fuel (SMF) is a type of solid fuel rod design that disperses TRISO coated fuel particles directly into a kind of matrix. SMF is expected to provide improved performance because of the elimination of cladding tube and associated ...

Effects of waterlogged fuel rod rupture on adjacent fuel rods and channel box under RIA conditions. [PDF]
Journal of Nuclear Science and Technology, 1987 This paper describes the results of in-pile experiments and analyses to study the influence of waterlogged fuel rod rupture to the adjacent fuel rods and channel box under reactivity initiated accident (RIA) conditions. A single waterlogged fuel rod surrounded by intact fuel rods m a flow shroud was irradiated by a large neutron pulse in the Nuclear ...
