PURPOSE:To enable to decrease the concentration of metallic impurity in the primary system of a nuclear reactor, by preventing corrosive product (C, P) produced in the condenser from flowing into the nuclear reactor, by providing sintered metallic filters in a condenser traversing over a flow path. CONSTITUTION:A filter 14 made of sintered metal is provided at least one place in the flow path 10 in a condenser. Four pieces of the sintered filter 14 are provided to each block of the condenser, that is 12 pieces in total in the condenser. The condensate from which C, P, especially in a clad, is removed by the sintered filter 14, flows out into a condensate purifier from a condensate outlet pipe via a condensate descending pipe 12. In such a manner, the condensate flowing into a hot well 9 from the condensate inlet 8, and flowing through the flow path 10 of a condenser which is partitioned by partition plates 5 to the direction of the arrow mark, is discharged from a condensate descending pipe 12. As a result, the concentration of metallic impurity in the primary system of an nuclear reactor can be decreased. |
