Abstract (en)
[origin: EP4080115A1] The present invention provides a loosening part capturing device for a steam generator (10) of a pressurized water reactor nuclear power plant, as well as a vertical type steam generator (10) of the pressurized water reactor nuclear power plant including the same. The loosening part capturing device is provided on a top plate (51) of a sludge collector (50). The top plate (51) is provided with a number of steam and water separator rising cylinders (41). Capturing enclosing plates (80) fixedly connected to the top plate (51) are provided between adjacent steam and water separator rising cylinders (41) on the periphery of the top plate (51). Two ends of each capturing enclosing plate (80) are respectively fixedly connected to outer surfaces of the water separator rising cylinders (41), and one end of each capturing enclosing plates (80) afar from the top plate (51), is provided with a folding plate (81) extending towards a center of the top plate (51).
