Preliminary observation of large scale UO/sub 2/ melt-concrete interactions and sustained steel-concrete interaction with an overlying water pool
An experiment description, presentation of results and an analysis of the results using a heat balance approach have been performed for the TURC-2 and SWISS-1 tests. In addition a CORCON comparison has been made for both tests also. The TURC-2 tests, a transient UO/sub 2//ZrO/sub 2/ concrete interaction test, showed no ablation for the duration of the test. Calculations indicate that stable crusting occurred immediately and prevented any erosion. In contrast, the CORCON comparison showed several cm of erosion, which implies the need for further code development and/or refinement. The SWISS-1 test was a sustained stainless steel concrete interaction test with water addition. The experimental result indicated a continuous steady erosion rate that was weakly coupled to the power generation rate for the duration of the test. Water addition showed no effect upon the erosion rate. This was attributed to the presence of a thick crust that effectively insulated steel melt from the water. A CORCON calculation indicated only half the erosion observed, again implying the need for further code development and refinement.
