The coolability of a continuous mass of primarily ceramic debris after relocation from the core to a lower plenum filled with water is being investigated. These debris coolability questions were raised during the recently completed Three Mile Island Unit 2 (TMI-2) vessel investigation project (VIP). The TMI-2 VIP results and other evidence 2-5 suggest that conduction through solidified debris was not the only debris cooling mechanism present. However, additional data are needed to identify what cooling mechanisms occurred and develop a database to model this cooling. Because of the potential impact of this additional margin, not currently considered in severe accident consequence analyses, a program has been initiated to address debris coolability questions. This program includes scaling analyses and a design feasibility study. This paper summarizes results from the first part of this program, a scaling analysis to estimate design parameters for experiments simulating debris cooling.
