Abstract
A suction strainer for straining water from the emergency suppression pool of a boiling water reactor includes a plurality of stacked, perforated disks having an internal core with a minimum internal radius r(x) that decreases with increased distance from the intake of the strainer, so that the core has a tapered profile. Internal radius r(x) may vary linearly or exponentially or a combination of both. The stacked, perforated disks each include a first surface that faces in the direction of the intake and a second surface, that faces away from the intake. A circumferential band may connect the first and second surfaces together.
Claims19
A suction strainer apparatus for straining water from the emergency suppression water source of a nuclear reactor, said strainer apparatus comprising:
- an intake;
- a plurality of stacked, perforated disks having a central core communicating with said intake, said central core having a central axis and an internal, minimum radius r(x) between said central axis and said disks,
- wherein said radius r(x) decreases with distance from said intake.
