Development and verification of a methodology for neutron noise response to fuel assembly vibrations

Annals of Nuclear Energy, 2020
Nuclear reactors are stochastic systems, in which several parameters fluctuate even during steady-state conditions. In addition, structural components like fuel assemblies, vibrate due to strong hydraulic forces.

Experimental investigation on split-mixing-vane forced mixing in pressurized water reactor fuel assembly

, 2020
In nuclear fuel assembly mixing vanes are fabricated on the spacer grids to promote diversion cross flow and turbulent mixing. In order to investigate the decay of diversion cross flow and turbulent mixing induced by the split mixing vanes, particle ...

Effect of bi-directional excitation input on boiling water reactor scrammability

Nihon Kikai Gakkai ronbunshu, 2020
When a large earthquake occurs, a boiling water reactor is automatically shutdown through the insertion of control rods among fuel assemblies. A fuel assembly can vibrate in-plane when two seismic waves act on it in directions at right angles to each ...
