Studies investigating cooling a continuous mass of relocated debris
- Lockheed Idaho Technologies Co., Idaho Falls, ID (United States). Idaho National Engineering Lab.
Scoping calculations were performed to gain insights about experiments examining the coolability of a continuous mass of debris that relocates to a waterfilled lower plenum. These coolability questions were raised during the recently completed Three Mile Island Unit 2 (TMI-2) Vessel Investigation Project (VIP). Results from the TMI-2 VIP and other evidence 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 to develop a database to model this cooling. To support the design of tests to obtain this data, analyses were performed to characterize the stress and thermal conditions experienced by the TMI-2 debris. Analysis results provide insights about debris coolability test material composition, decay heat, debris heat flux, and pressure requirements.
