In-core fuel freezing and plugging experiments: the tran series at Sandia National Laboratories
Conference
·
OSTI ID:5337180
A series of experiments in the Annular Core Research Reactor (ACRR) on freezing and plugging of molten UO/sub 2/ in small-diameter channels is described. Parameter ranges covered included fuel temperature 2900 to 3500/sup 0/C, steel temperature 400 to 900/sup 0/C, and driving pressure 10 to 15 bar. A stable UO/sub 2/ crust and fuel penetration distances of 67 to 87 cm were observed, with plugs at the leading edge of the flow in some cases. New models of the freezing and plugging process are being developed, since existing models are inadequate to describe all the phenomena observed.
