Can we predict critical heat flux in fuel assemblis by CFD methods?

Burtak, F.; Krepper, E.

Abstract

The presentation describes the industrial needs for the nuclear fuel elemet design particularly concerning the mixing vanes of spacer grids. Actual informations can be gained only by very expensive experiments. The actual state and the capabilities of CFD to support this process is referred.

Keywords: fuel elements; hot channel; critical heat flux; experiments; CFD simulations
