摘要

A strainer wall ( 1 ) to screen off a suction space ( 3 ) and a suction duct ( 5 ) connected to it in an emergency cooling system of a nuclear power plant includes at least one strainer wall element ( 2 ) which has an inlet side ( 12 ) and an outflow side ( 13 ), wherein the inlet side is essentially oriented perpendicular. The strainer wall element ( 2 ) is built up from a plurality of modular cassette units ( 11 ), which respectively contain a plurality of screen elements ( 17.1'-17 .n^m) open towards the inlet side ( 12 ) and connected to the outflow side ( 13 ).
