Design modification related to pressure resistance for water-cooled ceramic breeder blanket

Tanigawa, Hisashi; Sato, Satoshi; Kwon, Saerom; Enoeda, Mikio

For development of water-cooled solid breeder blanket, design of container structure of the blanket is modified to improve pressure resistance property. The higher temperature and pressure of the coolant water are preferable for efficiency in electric power generation. On the other hand, the smaller amount of the structural material is preferable in view of tritium breeding capability. The coolant pipe break leads to inner pressure loading on the container structure. To improve the pressure resistance property of the container, geometrical conditions of the container has been studied.
