FIELD: nuclear energy.
SUBSTANCE: invention relates to a drive for a control unit of a nuclear reactor. The drive consists of position sensor 1, an electromagnets bank (not shown), a cover (not shown), movement block 2, rod 3. Moreover, centring cone 4, made of a material soluble in the coolant, is attached to rod 3 to ensure remote centring of the position sensor in the drive rod of the control element when assembling the reactor.
EFFECT: eliminated the need to dismantle the position sensor when disassembling the reactor and install it when assembling the reactor.
