A STUDY OF FUEL ROD VIBRATION INDUCED BY COOLANT CROSS FLOW IN THE REACTOR CORE
Abstract eng: An analysis model has been drived on the vibrations of fuel rod induced by coolant cross flow in the reactor core. The force on the fuel rod was fitted out using parameters that describe rod position. The amount of energy a fuel rod receives from the coolant through one cycle of its vibration was calculated as a positional integration of the fluid force. The vibration mode of the fuel rod and the effective momentum flux of the fluid were calculated using the energy.
