ABSTRACT:
A cold trap disposed in a system in which liquid sodium is circulated as a heat exchanging medium, and adapted for removing impurities from the liquid sodium. The cold trap has a vessel in which defined are a cooling zone for cooling the liquid sodium containing the impurities, trapping zone in which the precipitated impurities are trapped and separated from the liquid sodium and an economizer zone in which the purified liquid sodium is reheated. The cooling zone and the economizer zone are disposed adjacent to each other, so that the purified sodium flowing through the economizer zone may be heated by the liquid sodium flowing through the cooling zone. The trapping zone is disposed in the passage of the liquid sodium interconnecting the heating and economizer zones.
