Abstract

The invention discloses a device and a method for partitioned loading of high-temperature gas cooled reactor cores. The device comprises a reactor pressure vessel, a burnup measuring system, a spent fuel system, a fuel loading and unloading system, a new fuel system and a three-way valve group; and a high-temperature gas cooled reactor fuel ball is loaded in the reactor pressure vessel, an outletin the bottom of the reactor pressure vessel is communicated with an inlet of the burnup measuring system, an outlet of the burnup measuring system is communicated with an inlet of the spent fuel system and an inlet of the fuel loading and unloading system, an outlet of the new fuel system is communicated with an inlet of the fuel loading and unloading system, an outlet of the fuel loading and unloading system is communicated with N feeding ports in the top of the reactor pressure vessel through the three-way valve group, a reactor core loading subarea in the reactor pressure vessel is dividedinto N loading subareas, one loading subarea corresponds to one feeding port, and each feeding port is communicated with the corresponding loading subarea. The device and the method can effectively solve the problems of non-uniform burnup and higher power peak factor of the reactor cores.

Description

technical field [0001] The invention belongs to the field of nuclear reactor core charging, and relates to a device and a method for zone charging of a high-temperature gas-cooled reactor core. Background technique [0002] At present, the core of the PWR nuclear power unit generally uses the whole group of fuel assemblies to carry out the optimized partition charging strategy, that is, the new fuel assemblies and the fuel assemblies that have gone through one fuel cycle cycle and two fuel cycle cycles are rearranged in the core. On the basis of improving the nuclear fuel burnup level of the reactor, the power distribution in the reactor core shall be flattened as much as possible, and the power peak factor shall be reduced; at the same time, the neutron leakage rate shall be reduced, and the neutron injection amount of the reactor pressure vessel shall be reduced. [0003] The high-temperature gas-cooled reactor is a spherical fuel element, which is transported one by one b...
