The utility model discloses a secondary filter screen blowdown system for circulating water of a nuclear power station. At present, when a pollution discharge electric door of an existing nuclear power station secondary filter screen system is closed for a long time or seawater is severely dirty, a secondary filter screen cannot normally discharge pollution. The nuclear power station circulating water secondary filter screen blowdown system comprises a purification separator (1), a high back pressure condenser (2) and a low back pressure condenser (3), the high back pressure condenser and the low back pressure condenser are connected through a high and low back pressure condenser connecting pipe (4), the high back pressure condenser is connected with a circulating water inlet pipe (5), the low back pressure condenser is connected with a circulating water return pipe (6), and the purification separator (1) is connected with the high and low back pressure condenser connecting pipe (4).
