Abstract

One current concept in fusion blanket module design is to utilise water as coolant and liquid lithium-lead as breeding/neutron-multiplier material. Considering the possibility of certain off-normal events, it is possible that water leakage into the liquid metal may occur due to a tube rupture. The lithium-lead water contact could lead to a thermal and chemical reaction which would provoke an intolerable pressure increase in the blanket module. For realistic simulation of such in-blanket events, the BLAnket Safety Test (BLAST) facility has been built. It simulates the transient event by injecting subcooled water under high pressure into a stagnant pool of about 500 kg liquid Pb-17Li. Eight fully instrumented large break tests have been carried out under different conditions. In this paper, the results of all tests performed are presented and discussed.
