Evaluation tool used thermal conduction analysis, which calculates an amout of erosion of refractory materials and temeprature change in refractory materials and concretes, has been constructed in order to verify an effect of refractory materials laid for actual plants. The tool contains some models based on the knowledes obtained from Phase I project and the MCCI tests, and the analyses for those tests by using the tool confirmed the validity of the tool.
