MCCI PROJECT CSNI2003/01 Arrived
The purpose of the OECD/MCCI Program was to carry out reactor materials experiments and associated analysis to achieve the following two technical objectives: 1) resolve the ex-vessel debris coolability issue by providing both confirmatory evidence and test data for coolability mechanisms identified in previous integral effect tests, and 2) address remaining uncertainties related to long-term 2-D core-concrete interaction under both wet and dry cavity conditions. Two types of separate effects tests were conducted to provide data on key melt coolability mechanisms that could provide a pathway for achieving long-term debris cooling and stabilization.
The Small Scale Water Ingression and Crust Strength (SSWICS) tests provided data on the ability of water to ingress into core material, thereby augmenting the otherwise conduction-limited heat transfer process. Dryout heat flux data obtained from these experiments can be used directly in existing models for evaluating the effect of water ingression on mitigation of ex-vessel accident sequences involving core-concrete interaction. The crust strength data obtained as part of this work can be used to verify the concept of sustained melt/crust contact due to crust instability in the typical 5-6 m cavity span of most power plants.
The Melt Eruption Test (MET) focused on providing data on the melt entrainment
coefficient under well-controlled experimental conditions. The experiment featured an inert basemat with remotely controlled gas sparging, since this is the most important parameter in determining the entrainment rate. Entrainment rate data obtained from this test can be used directly in existing models for evaluating the effect of melt ejection on mitigation of the core-concrete interaction.
The Core Concrete Interaction (CCI) tests provide data on the lateral vs. axial power split as molten corium ablates concrete containment structures. The tests were conducted with large-scale concrete crucibles that allowed for 2-D concrete ablation. The rate of lateral and axial erosion was measured for two different types of concretes: siliceous concrete and limestone common sand concrete.
