LEAD GROUP METAL CIRCULATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a lead group metal circulation device capable of reducing corrosion effects. SOLUTION: In a lead group metal circulation device for circulating fluidic lead group metal as metal including at least lead in a loop 1 using a pump 2, a cooling means 5 placed in the loop 1 for cooling the lead group metal circulating in the loop 1, bypass lines 27 and 29 placed in the loop 1 downstream the cooling means 5 for bypassing a part of or whole lead group metal circulating in the loop 1 from the loop 1 and returning to the loop 1 upstream the cooling means 5 and an impurity removing means 28 placed in the bypass lines 27 and 29 for removing impurity contained in the by passed lead group metal are provided.
