Proposal of assessment of structural integrity on severe accidents for JSFR

Hirose, Yuichi*; Ando, Masanori ; Onizawa, Takashi ; Wakai, Takashi ; Sato, Kenichiro*

The purpose of this study is to develop assessment of structural integrity for JSFR's primary system made from 316FR steel and Mod.9Cr-1Mo steel in severe accidents that sodium temperature exceeds the design basis temperature as 650 $^{circ}$ C. It is important of sodium boundary to prevent damages in high-temperature environment. From this standpoint, the way of stress calculation, evaluation formula including limiting value, safety factor and cumulative damages are considered. This paper provides example to apply these assessment for JSFR under development in Japan.
