Abstract

The embodiment of the invention discloses an oxygen content control device and a reaction system, and relates to the technical field of nuclear engineering and nuclear, a reactor is associated with the oxygen content control device, so that the oxygen content control device controls the content of dissolved oxygen in a lead-bismuth coolant, the continuous passivation capability of the lead-bismuth coolant to a structural material is maintained, the material corrosion is prevented, and the service life of the reactor is prolonged. And safe operation of the reactor is ensured. The oxygen content control device comprises a shell, a driving part and an oxygen control reaction part, a reaction cavity is formed in the shell, the shell is provided with an insertion end, the insertion end is communicated with a reactor, the insertion end is provided with a suction inlet and a discharge outlet, and the suction inlet and the discharge outlet are both communicated with the reaction cavity; the driving part is arranged on the shell and is used for driving a lead-bismuth coolant in the reactor into the reaction cavity from the suction inlet; and the oxygen control reaction part is arranged in the reaction cavity. The oxygen content control device is used for adjusting the oxygen content in the lead-bismuth coolant.

Description

technical field [0001] The present application relates to, but is not limited to, the fields of nuclear engineering and nuclear technology, and in particular, relates to an oxygen content control device and a reaction system. Background technique [0002] Lead Bismuth Alloy (LBA), as a low melting point and high boiling point alloy, has excellent nuclear physical and thermal properties, and is chemically inert. It is an excellent fast neutron reactor coolant. The lead-bismuth cooling fast neutron reactor is one of the fourth-generation advanced nuclear reactor types, but lead-bismuth alloys are highly corrosive to the reactor structural materials at high temperatures, and the corrosion of lead-bismuth alloys to structural materials will seriously threaten the reactor equipment. safe operation. [0003] To this end, the present application provides an oxygen content control device and a reaction system. SUMMARY OF THE INVENTION [0004] The embodiments of the present appl...
