GRAPHITE SAMPLING DEVICE IN CHANNEL-TYPE REACTORS Russian patent published in 2021 - IPC E21B49/06 G21C17/02 

Abstract RU 2750374 C1

FIELD: nuclear power industry.

SUBSTANCE: invention relates to a device for drilling out cores from the walls of wells or channels and can be used in the field of nuclear power to obtain samples of graphite from channel-type reactors, for example, the RBMK. The device contains a bearing bar, a tubular cutter, a mechanism for rotation and feeding of a tubular cutter. In this case, the bearing bar is prefabricated and consists of segments, the device contains a sampler, in the body of which a tubular cutter and a mechanism for rotation and supply of a tubular cutter are located, the sampler body contains at least one pneumatic centralizer located on its outer side, a mechanism for rotation and supply of a tubular cutter in part of the rotation of the tubular cutter contains a pneumatic motor with the ability to interact with a reducer, a gear and a gear on the carriage on which the tubular cutter is located; the control unit is connected to the air preparation unit by a loop.

EFFECT: qualitatively improved, reliable and automated process for sampling graphite.
