Neutronic Simulation of Fuel Assembly Vibrations in a Nuclear Reactor [PDF]
Nuclear Science and Engineering, 2020 The mechanical vibrations of core internals as fuel assemblies cause oscillations in the neutron ux that require, in some circumstances, to operate nuclear power plants at a reduced power level. This work simulates and analyses the changes of the neutron ux throughout a nuclear core due to the oscillation of a single fuel assembly without considering ...
