Abstract

This paper has been prepared in the framework of the safety analysis of blanket designs proposed for NET (Next European Torus). Two different concepts of blanket using Li-17Pb-83 as breeder and pressurized water as coolant have been developed with a "modular" and a "tubular" configuration, respectively. In both concepts the shell of the vessel containing the breeder represents the first barrier against accident propagation in case of coolant pipe break (LOCA). A mechanical analysis of the "modular concept" is presented where the vessel shell is subjected to the pressure transient due to a LOCA. The mechanical behaviour, evaluated in dynamic conditions taking into account non-linearities and fluid - structure interaction, shows that the structural reliability cannot be guaranteed, and suggests to continue the development of the "tubular concept" for which a much better mechanical behaviour is expected.
