Abstract：Arrangement design of Cooling Water Outlet Structure is a key problem for Coastal Nuclear Power Station. Cooling
Water Outlet structure ensures the normal operation of units，and it protect the equipments of Coastal Nuclear Power Station
against storm surge by Cooling Water Outlet Structure. This paper illustrates the design criterions which need to be followed of
hydraulic arrangement in Coastal Nuclear Power Station，as well as provides the experience in the Cooling Water Outlet struc原
ture arrangement design of Coastal Nuclear Power Station.
