REACTOR ASSEMBLY/DISASSEMBLY METHOD Russian patent published in 2024 - IPC G21C17/00 G21C7/12 

FIELD: nuclear energy.

SUBSTANCE: invention relates to the field of nuclear energy, in particular, to a nuclear power plant with hull-type reactors, and concerns a method of assembling/disassembling a reactor. The method of assembling / disassembling the reactor has the following sequence of operations: disconnecting the rods of the drives of the control and protection system (CPS) and the absorption rods of the CPS on the block of protective pipes, fixing the rods of the drives of the CPS on the block of protective pipes. At the same time, the position sensors remain on the upper block. Connection of the drive rods with the assemblies of the absorption rods of the control and protection system on the block of protective pipes. The rods of the actuators are centered with the position sensors by means of a control body drive. The drive of the regulating body contains a displacement unit, a rod, and a position sensor. The position sensor does not contain protruding parts beyond the displacement unit.

EFFECT: invention makes it possible to abandon the dismantling of the position sensor from the upper block during disassembly of the reactor and the installation of the position sensor on the upper block during assembly of the reactor during scheduled preventive maintenance of the reactor installation.
