The TRAN B-Series experiments are being conducted at Sandia National Laboratories to investigate the characteristics of fuel removal/freezing through the upper axial blankets of a liquid-metal fast-breeder reactor during the transition phase of a hypothetical core-disruptive accident. The first experiment in this series, TRAN B-1, was performed in February 1983 and the results are reported herein. This experiment involved the injection of molten UO/sub 2/ into an annular flow channel. Previous experiments had shown crusts to be stable on the inside of a cylindrical flow channel. This experiment was intended to investigate whether the conclusion of crust stability could be extended to freezing on the outside of cylindrical rods (the more prototypic geometry of the upper axial blankets). The results of the TRAN B-1 experiment, consisting of data from online instrumentation and postirradiation examination, indicate that the crusts on both inner and outer surfaces of the annular channel were stable during the duration of the fuel flow.
