Development of creep analysis system for ADS beam window

Watanabe, Nao ; Sugawara, Takanori ; Nishihara, Kenji ; Kaji, Yoshiyuki

In the design of Accelerator-Driven System (ADS), a beam window is one of the structures used under severe conditions. Since the maximum temperature of the beam window at rated operation will be more than 500 $^{circ}$ C, a creep damage evaluation has been required. Therefore, we have developed a coupled analysis system on ANSYS Workbench to evaluate the creep strain quantitatively. In this system, temperature distribution of the beam window is calculated by the coupled analysis of particle transport and thermal hydraulics analyses, and then is used as an input data for a creep analysis. Calculation result by this analysis system showed that the creep strain after the rated operation was less than 0.1%.
