Temprature effects of chemisorption of CsOH vapor generated at about 1000K on SUS were examined using the TeRRa test apparatus with temperature gradient tube from 1273K to 473K. The chemisorption amounts were measured as increased mass of test pieces in the temperture gradient tube. These results were calcurated using the SA code, SAMPSON. For the test analysis, the thermal hydraulic analysis (THA) module and the FP transport analysis (FPTA) module were used. The FPTA could calcuculated the chemisorption amount within the experimental error range using the gas temperature calculated by the THA module. So the temperature dependency of the chemisorption correlation used in the calcuration was validated.
