Facility Details: ACRR-MP

Organization / Localization: INL
Country: Idaho Falls, ID, USA
Test Identification: MP1
SA-Related Topics / Phenomena: investigate late phase melt progression processes in degraded fuel geometry. Specifically, the melting dynamics, molten pool formation and growth, and crust failure and migration through intact structure were investigated.
Measured Parameters: 32 fresh UO2 rods, 3 kg UO2/ZrO2 fuel debris overlying rod stub array, max T=3400 K
