Abstract
A back-flushable strainer is used for filtering water to an emergency cooling system in a nuclear power plant having a reactor arranged in a containment whose lower part forms a condensation pool in which the strainer is mounted. The strainer has a suitably cylindrical strainer wall having a plurality of perforations through which the water flows from the outside and in when filtering, while the direction of flow is the reverse in backflushing. A number of wings are arranged on the outside of the strainer wall, dividing a residue or fibre mat built up on the outside of the strainer wall into a number of sections which separately are more easily released than a continuous, circumferential fibre mat.
