Ex-vessel debris coolability is an important light water reactor (LWR) safety issue. For existing plants, resolution of this issue will confirm the technical basis for severe accident management guidelines (SAMGs). For new reactors, understanding this issue will help confirm the effectiveness of the design and implementation of new accident mitigation features and severe accident management design alternatives (SAMDAs). The first OECD-MCCI program conducted reactor material experiments focused on achieving the following technical objectives: i) provide confirmatory evidence and data for various cooling mechanisms through separate effect tests for severe accident model development, and ii) provide long-term 2-D core-concrete interaction data for code assessment and improvement. As one of the steps required to satisfy these objectives, the Management Board (MB) has approved the conduct of a third Category 2 Test to supplement the two that have already been approved. In particular, the following PRG recommendation was approved at the 5th PRG meeting: Regarding the Category 2 small scale tests, PRG recommends that a SSWICS-13 test be performed with the bottom injection system partitioned into 2 parts, one with water only, the other with water and nitrogen. The test design report was prepared by the OA with input from KAERI. This report describes the test results for the third Category 2 test, which is denoted SSWICS-13.
