FIELD: machine building.
SUBSTANCE: invention relates to drive (100) for an in-reactor neutron measurement system. Device includes safety circuit (10) between power supply (20) and drive motor (3). Safety circuit (10) is provided inside cover (8) and performs switching between conducting state, in which power may be supplied to drive motor (3), and cut-off state, in which power can not be supplied to it, depending on state installation of cover plate (8). Safety circuit (10) is controlled so as to be in conducting state in response to state in which cover (8) is installed on base part (9), and is controlled so as to be in cutoff state in response to state in which cover (8) is not installed on base part (9).
EFFECT: higher safety during operation of a driving device for an in-reactor neutron measurement system.
