Mechanical model for the motion of RPV internals affecting neutron flux noise

Mechanical model for the motion of RPV internals affecting neutron flux noise

In the decade after 2000, the amplitude of the neutron flux fluctuations in German 1300 MWe class PWR built by Kraftwerk Union (KWU) increased and later decreased significantly. To further investigate the hypothesis that changes in the mechanical properties of the fuel assemblies (FAs) and subsequen...
