Static reactor container cooling system

In a static container cooling system, a mechanism for removing aerosol is formed to a steam box by suddenly bending a flow of an atmospheric gas in a container. In addition, a reservoir for storing removed aerosol is formed, and a structure for preventing intrusion of the removed aerosol is disposed. A structure which tends to cause inertia collision deposition is formed to a PCCS for removing the aerosol, and in this case, if the aerosol removed compulsorily by the inertia collision deposition is left at a position to disturb the flow of fluid, the possibility of clogging PCCS is increased than the case where the aerosol is not removed. Accordingly, it is necessary to store the removed aerosol at a position not to disturb the flow of fluid. Further, insoluble aerosol having an extremely fine grain size is accumulated in a water sealing portion which connects a condensate draining tube and an emergency reactor core cooling system pool and gradually closes the water sealing pipelines. Also in this case, clogging is prevented by disposing an aerosol reservoir to the water sealing pipeline. (N.H.)
