taking a sample from the molten mass by injection casting each of the metal product samples had a copper content of about 2 54 wt for a complete reaction of uranium metal and cucl 2 in the presence of a salt fraction of 19 6 wt 2 51 wt copper in the metal product was predicted taking into account experimental error the ratio of the expected and measured values u201c e m u201d of copper content in the condensate was 0 99 indicating complete reaction of cucl 2 and uranium metal in this example 1002 g of mncl 2 and 15 913 g of uranium metal disks and sheets were combined in a reaction vessel along with licl u2014 kcl eutectic salt the reaction vessel was subsequently loaded into a furnace the operating pressure in the reaction vessel was decreased to about 100 torr to prevent the premature distillation of mncl 2 following the decrease in pressure the temperature was increased to about 650 u00b0 c both temperature and pressure were maintained for about 5 hours to allow reaction 1 to proceed to completion following the reaction period the furnace was heated to a maximum temperature above 1132 u00b0 c to distill the chloride salt products following distillation the amount of manganese in the condensate was analyzed using icp aes from this analysis it was determined that the condensate contained a negligible amount of manganese 6700 ppm indicating that reaction 1 went substantially to completion 1494 g of cucl 2 was added.
