DOI: 10.1016/j.anucene.2019.07.017
Abstract: Abstract Fuel rods, one of the most important components in the nuclear reactor core, are usually supported by spacer grids along the axial direction. Since those fuel rods are long and slender, flow-induced vibration (FIV)… read more here.

DOI: 10.1016/j.nucengdes.2021.111233
Abstract: Abstract Horizontal flow in the lower part of the reactor pressure vessel was found responsible for the so-called baffle jets impinging in the direction almost perpendicular to the nuclear fuel rods axes. This flow may… read more here.
