Prediction of the nuclear fuel rod abrasion in the probability sense
Original language description
The paper deals with the upper and lower limits estimation of the friction work and fretting wear in the contact of nuclear fuel rods with fuel assembly (FA) spacer grid cells. Design and operational parameters of the FA components are understood as random variables defined by mean values and standard deviations. The gradient and three sigma criterion approach is applied to the calculation of the upper and lower limits of the friction work and fretting wear in particular contact surfaces between the fuel rod cladding and some of spacer grid cells.The fuel assembly vibration is excited by pressure pulsations. The method is applied for hexagonal type nuclear fuel assembly in the VVER type reactors.
