This study measured the dryout heat fluxes for bottom heated debris beds, where small spherical particles were placed on a 75mm diameter heating surface. The data were obtained by varying the particle size in the range of 3 to 10mm, and compared with the predicted results with the one dimensional model proposed by Lipinski.
