Debris bed and sacrificial materials interactions at high temperatures. [LMFBR]
Conference

OSTI ID:6797308
A series of high temperature furnace experiments were conducted to examine materials interactions under possible post-accident heat removal conditions following a hypothetical core disruptive accident. The study of material interaction within simulated dried-out debris beds and between such debris beds and candidate core retention materials produced results with significant reactor safety implications. Urania sintering dependence on particle size was examined because sintering may determine characteristics of the crust between molten fuel and structural or sacrificial material. The behavior of a mixed UO/sub 2//steel simulated debris bed was studied above the steel melting point. Finally the interaction of a particulate UO/sub 2/ bed with Harklase (98% MgO) brick was examined at various temperatures to determine the characteristics to be expected.
