Abstract (en)
[origin: ES8204534A1] Device for reducing thermal stresses on a heat exchanger between two counterflow-circulating liquid alkali metal circuits comprising an annular cylindrical nest of tubes surrounding an axial pipe for the introduction of the liquid alkali metal to be heated and extended by an annular pipe for discharging the heated liquid alkali metal, wherein it comprises in the said annular pipe for discharging the heated liquid alkali metal means for radially homogenizing the temperature of the alkali metal, said means comprising pipes which, at the outlet of the nest of tubes, tap a part of the relatively hotter alkali metal flowing along the outer periphery of the annular pipe to bring it into its flow area closest to the axis.
