Abstract
Cold trap for eliminating the impurities present in a polluted liquid metal. It comprises a body provided with an intake pipe for the polluted liquid metal and an internal structure defining a passage for the metal, said structure being successively provided with means for cooling the liquid so that it can be cooled to a cold point temperature below the impurity saturation temperature and bring about a crystallization of the impurities, means for retaining the impurities and a discharge pipe for discharging from the body the impurity-free metal and means for reinjecting upstream of the cooling means part of the fluid which has passed through the impurity retention means. Application to liquid metal-cooled nuclear reactors.
