In spite of the low fuel failure rate in currently operating water cooled nuclear power reactors,
operations are increasingly demanding with higher burn-up, power increases, cycle lengths …

Bubble sliding is an important phenomenon in subcooled flow boiling that contributes
significantly to overall heat transfer, especially in geometrically constrained geometries …

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 …

In order to achieve high-fidelity PIV measurement for cross flow in rod bundles, the
