FRICTION-VIBRATION INTERACTIONS OF THE NUCLEAR FUEL RODS

Original language description

The paper deals with mathematical modelling of friction-vibration interactions of nuclear fuel rods in the hexagonal type nuclear fuel assembly. The fuel rods are transversally linked by three spacer grid cells to each other inside the fuel assembly skeleton in several vertical levels. The fuel assembly vibrations, caused by the fuel assembly support plates motion in the reactor core, generate variable contact forces between fuel rods cladding and spacer grid cells. Friction effects on stick-slip motion in contact surfaces are important to calculation of expected lifetime period of nuclear fuel assembly in terms of fuel rod cladding fretting wear.
