Estimates of the end-state core configuration have been developed from recent inspection of the lower regions of the TMI-2 core, core support assembly, and lower plenum regions. The inspection data have provided a basis for estimating the extent of damage to the core and core support structures and have confirmed that the migration pathway of the molten core material to the lower plenum occurred in the east quadrant of the reactor vessel. This paper integrates the core inspection data with other TMI-2 data and supporting analysis to update the best-estimate core damage progression scenario.
