The XR1-1 and XR1-2 (Ex-Reactor) experiments, investigating metallic core melt relocation in boiling water reactor (BWR) geometry were performed in August and November of 1993. The XR1 tests represented the BWR control blade and channel box structures in the lower part of the BWR core as metallic core materials are beginning to melt and drain downwards. The purpose of this experiment program is to examine the behavior of downward-draining molten metallic core materials in a severe reactor accident in a dry BWR core, and to determine conditions under which the molten materials drain out of the core region or freeze to form blockages in the lower portion of the core.
