Japanese Patent JPS5242726
Kind Code:
B2
Abstract:
Refining or the removal of impurities from sodium traveling within a closed circuit for heat exchange of a fast breeder nuclear reactor or the like is obtained by means of a sodium refining chamber as a part of the circuit having therein netlike members disposed against the sodium flow and a heat exchanger for selectively heating and cooling of the sodium as it flows around the netlike members for the precipitation of the impurities during cooling and for the remelting of the impurities during heating. The thus remelted impurities during heating are discharged through a discharge pipe in the lower portions of the sodium flow adjacent the netlike members. The netlike members are constructed of large mesh, knitted wire material having the wire strands constructed of a plurality of fine wires, with the adjacent layers of net having spaces between their faces. The net layers are preferably corrugated, with the direction of corrugation being inclined with respect to the direction of knitting and further being inclined with respect to the corrugations of an adjacent layer. The travel of the sodium through the netlike members is such that it will be in counter flow heat exchange relationship, with the inter-position of a heat conductive flow separator, with the flowing liquid sodium that has just passed through the netlike members.
