Rivard, J B

A LMFBR accident in which molten core material is suddenly quenched with subcooled liquid sodium could result in extensive fragmentation and dispersal of fuel as subcritical beds of particulate debris. The primary safety concern for these debris beds is their capacity for transfer of the fission product decay heat to overlying liquid sodium by natural processes. The objective of the D-series of experiments is to closely simulate decay-heated debris and to determine the limits of stable operation wherein dryout does not occur. This is accomplished by fission heating enriched UO/sub 2/ particulate in subcooled liquid sodium in the Annular Core Pulse Reactor (ACPR). Results to date are presented.
