Gas/liquid oxygen-transfer to flowing lead alloys
2011
For the application of liquid lead or lead-bismuth eutectic as coolant in nuclear reactors, the concentration of dissolved oxygen, determining the compatibility with steels used as construction materials, is of critical importance. In general, oxygen has to be added continuously to the liquid metal, so as to compensate for consumption by oxide formation on the surface of the reactor components. A potential method of keeping the oxygen concentration in a favourable range is transferring oxygen from an oxygen-containing gas, which is investigated on the basis of the experience from operating a gas/liquid transfer device in the CORRIDA loop. Conclusions on oxygen transfer in industrial-scale systems are drawn.
