Structural steels are susceptible to dissolution when exposed to liqui
d Pb-17Li. In order to remove the corrosion products transferred into
the alloy, purification systems may be used. The efficiency of a cold
trap fitted to the Anapurna liquid metal loop has been studied. The re
moval of nickel from solution in Pb-17Li has been shown to be possible
by adding manganese to the Pb-17Li. Experiments carried out with a co
ld trap temperature of 523 K and an alloy temperature of 673 K have sh
own that nickel concentration as low as 1 wppm may be achieved by this
method. The result is interpreted by the formation of nickel-manganes
e compounds deposited in the cold parts of the trap. This observation
which suggests an interaction between both nickel and manganese in Pb-
17Li is confirmed by equilibrium tests of Ni-Mn alloys with Pb-17Li.
