REACTOR BODY MONITORING SYSTEM Russian patent published in 2020 - IPC G21C7/36 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment in the field of nuclear power engineering, in particular to devices for monitoring inside WWER reactor housing. Control system of the reactor housing comprises a frame that can move along the perimeter of the upper flange of the reactor housing, diagnostic equipment, electric motors with encoders. Distinctive feature of control system is that it comprises metal road arranged on upper flange of reactor housing, at least one upper circular motion module arranged on a metal road and having an electric motor with an encoder. At that, on upper module of circular movement frame is fixed, made in form of truss, on which there are at least one lower module of circular movement and at least one universal carriage for installation of diagnostic equipment. Universal carriage is equipped with an electric motor with an encoder and is placed on the truss with possibility of movement along it in vertical direction. Protective guard for safety of personnel is fixed on the upper flange of the reactor housing.

EFFECT: technical result of the invention consists in reducing the time of the reactor body monitoring procedure from the inside, the measurements accuracy, simplification of processes of preparation of the system for operation and decontamination after control, improvement of fail-safety, measures for safety of work performed by service personnel.
