Small-Scale Water Ingression and Crust Strength Tests (SSWICS) SSWICS-6 test data report : thermal hydraulic results, Rev. 0.

OECD/MCCI 2-D Core Concrete Interaction (CCI) tests : final report February 28, 2006.

“…59.0 -90. 3 Nearly continuous eruptions with predominately extrusion-type eruption processes occurring along both walls and less frequently near the center of the crust. Several eruptions lead to flows that cover 50+ % of the crust surface.…”

“…140. 3 Lance used to breach the crust. Two load peaks observed: the first peak was 0.34 kN at +22.2 cm elevation, while the second was 0.67 kN at +20.0 cm elevation.…”

“…Further examination of the data indicates that the heat flux increased with concrete gas content. For reference, the SSWICS water ingression heat transfer correlation 3 predicts an ingression-limited heat flux in the range of 40-90 kW/m 2 for the concrete types and crust concrete contents shown in Table 3-20. The heat fluxes realized in the tests are as much as an order of magnitude higher than that predicted by the correlation.…”

“…Aside from lowering the melting point of the mixtures, 23 the additives were incorporated to account for concrete erosion that is expected to occur during the corium spreading phase following breach of the Reactor Pressure Vessel (RPV). 24 As part of the development work for the SSWICS test series, 3,5 specially designed exothermic chemical mixtures (or "thermites") were developed to produce the particular melt compositions shown in Table 1-1. The reader is referred to the individual data reports [14][15][16] for additional information regarding the details of the thermite designs.…”

“…177.4 -189. 3 Intermittent eruptions near south wall. Eventually a large hole develops through the crust near the centerline.…”
