TUBULAR FUEL RODS MOVEMENT INSIDE THE ASSEMBLY Russian patent published in 2018 - IPC G21C1/22 

FIELD: nuclear engineering.

SUBSTANCE: invention relates to the fission in the nuclear reactor intensity control and represents the fission nuclear reactor operation method, and the nuclear reactor. Reactor comprises the reactor core and reservoir with the coolant. At that, the reactor core includes the fuel magazines assembly. Each fuel magazine is arranged substantially vertically and includes one or more fuel rods containing the fissionable fuel. Fuel rods are immersed into the coolant. Method comprises fuel concentrations and fission rates in each of the fuel magazines monitoring and simulation. Depending on the monitoring and simulation results, performing the fuel magazines horizontal movement inside the assembly, eliminating the fuel rods rising above the coolant.

EFFECT: providing the possibility of spent fuel magazine extraction from the assembly horizontal peripheral part without the spent fuel magazine removal from the coolant to control the fission rate in the reactor core.
