ABSTRAKT

The state-of-the-art experimental and analytical work on post CHF effects of spacer grids and flow blockage in rod bundles is reviewed and summarized from the point of view of basic heat transfer effects and mechanisms. A perspective is given on what future work is needed to help validate state-of-the-art post CHF grid and blockage heat transfer models.
