VVER REACTOR INTERNALS MONITORING SYSTEM Russian patent published in 2024 - IPC G21C17/00 

FIELD: measurement.

SUBSTANCE: invention relates to measuring equipment in the field of nuclear power engineering, for inspection of technical condition of the main metal and welded joints of a core barrel (hereinafter CB) and a baffle of CB from the inside. VVER reactor internals control system, namely CB with baffle, includes examination module arranged on retractable and unfolding mechanism with assembly of attachment to hole on plate, and control mechanism. CB is placed in the CB inspection shaft filled with water, and is coupled with the transportation device of CB (CBTD), in which there is a retractable and unfolding mechanism in the form of a telescopic manipulator with a unfolding console having a rotating part of the console and a float on the CBTD plate above the hole by means of a fastening assembly.

EFFECT: invention makes it possible to use a control system of CB with a baffle from the inside directly in the CB inspection shaft, simplified process of preparing the system for operation and maintaining accuracy of measurements.
