  • Cleaning mechanism for penetration interfaces in nuclear pressure vessels
    Patent number: 4910823
    Abstract: A method and apparatus, comprising a tool having a clam shell design, for sealing the interface volume between the internal wall of a reactor pressure vessel and submerged piping that penetrates the wall, and for cleaning the interface volume using a series of hydraulic and pneumatic operations. The tool is operable from a remote suface location, using a robotic arm for fine positioning, to clamp around the penetrating pipe. Hydraulic nozzles compressed air and mechanical brushes on the tool may be used to dislodge sediment in the interface volume.
