ABSTRACT:
A strainer device for filtering water to an emergency cooling system in a nuclear power plant includes a housing or tube having a perforated or apertured strainer wall through which water may flow from the outside and into the interior of the housing in connection with the regular filtration of water taken in. A water-receiving accumulator tank is connected to the cavity of the strainer housing and a source of pressurized gas is connected to the tank in order, if required, to feed pressurized gas into the tank so as to momentarily force water out therefrom and into the cavity of the strainer housing while backflushing the same.
