MECHANICAL ANALYSIS OF A MODEL OF THE BREEDING BLANKET OF NET IN FAULTED CONDITIONS
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.
