Molten core debris-sodium interactions: M-Series experiments. [LMFBR]

PDF Version Also Available for Download.

Description

Five new kilogram-scale experiments have been carried out. Four of the experiments simulated the situation where molten core debris flows from a breached reactor vessel into a dry reactor cavity and is followed by a flow of sodium (Ex-vessel case) and one experiment simulated the flow of core debris into an existing pool of sodium (In-vessel case). The core debris was closely simulated by a thermite reaction which produced a molten mixture of UO/sub 2/, ZrO/sub 2/, and stainless steel. There was efficient fragmentation of the debris in all experiments with no explosive interactions observed.
