Modelling of the Pb17Li/water interaction within a blanket module

In the frame of the WCLL (water cooled lithium lead) programme, experimenta l and theoretical activities are devoted to study the interaction between t he cooling water and lithium lead alloy. In case of large leakage, the inte raction can lead to a pressurisation of a blanket module which can challeng e its integrity. Therefore, it is important to assess its consequences as a ccurately as possible. In order to make possible the modelling of the next LIFUS 5 experimental activity and to correctly understand the phenomena con nected to a large break LOCA (loss of coolant accident) in the breeder zone in real conditions, a mathematical model has been tested on the BLAST expe riences carried out at JRC-Ispra in the past years. A good fitting between experimental and modelling results has been obtained as shown in this paper . (C) 2000 Elsevier Science B.V. All rights reserved.
