Neutronic Simulation of Fuel Assembly Vibrations in a Nuclear Reactor [PDF]
Nuclear Science and Engineering, 2020 The mechanical vibrations of fuel assemblies have been shown to give rise to high levels of neutron noise, triggering in some circumstances the necessity to operate nuclear reactors at a reduced power level. This work simulates and analyses the effect in the neutron field of the oscillation of one single fuel assembly without considering thermal ...
