Abstract
A flexible penetration attachment for BWR wet-well strainers is provided that causes a suction pipe to communicate with liquid in the wet-well through an aperture in a wet-well wall. The penetration includes a boot for defining an outer circumference of the aperture. A suction pipe having an outer surface extends through the aperture such that an annular space is defined between the aperture outer circumference and the suction pipe outer surface. A resilient seal having a generally U-shaped cross section with first and second ends is placed within the annular space. The first end is fixedly secured to the outer surface of the suction pipe and the second end is fixedly secured to the aperture outer circumference such that the suction pipe may move in response to a force applied to the suction pipe.
