PROCEDIMIENTO PARA LA LIMPIEZA DE UN DEPURADOR FRIO INCORPORADO EN UN CIRCUITO DE METAL LIQUIDO

摘要

A cold trap incorporated into a liquid metal circuit is cleaned by introducing an alkali metal hydroxide in liquid state into the trap and in excess compared with solubility limits of deposited impurities, then heating the trap to totally transform the impurities into liquid phases and draining off these liquid phases. The cleaning operation is carried out in the absence of water.
