A new test facility, COOLOCE has been designed and built for experimental investigations of coolability of porous particle beds with a flexible geometry. The main objective of the experiments is to compare the coolability of a heap-like (conical) particle bed configuration to that of an evenly-distributed cylindrical particle bed. The first experiments with a conical particle bed have been performed. The results suggest that the dryout power is relatively high in the conical particle bed. In addition to the experimental work, analytical work on the issue, including code development, is performed.
