Abstract

The invention discloses a device and a method for adding zinc to ADS reactor lead-bismuth eutectic alloy. The device comprises an ADS reactor with a zinc adding tube, wherein a zinc adding tube 1 passing through a zinc adding hole is arranged in the ADS reactor, the zinc adding tube 1 extends to be close to a reactor core of the reactor, a closeable sealing cover is arranged in the zinc adding hole, a containing part and a spraying part are arranged outside the sealing cover, so that zinc powder or weak acid zinc salt or an additive containing zinc element can be conveniently added to the reactor core through the zinc adding hole, so that a cooling agent in the reactor core contains the zinc element, and by controlling the addition of the zinc element, a layer of dense oxide thin film is formed inside the reactor core, so that the service life of the reactor is prolonged, and the safety of the reactor is improved.

Description

technical field [0001] The invention relates to the field of nuclear reactor safety, and improves the performance of the reactor by adding zinc to the ADS reactor, in particular to a device and method for adding zinc to the lead-bismuth eutectic alloy of the ADS reactor. Background technique [0002] Since the late 1980s, ADS, as an advanced transmutation reactor type, has gradually become a hot spot in international research. The United States, the European Union, Japan and other countries have included the research on ADS subcritical reactors in their national medium and long-term development plans. Its composition includes: exogenous neutron target, medium-energy high-current proton accelerator and subcritical reactor. It is a high-efficiency nuclear waste transmutation furnace and incinerator. Preferred coolant materials and spallation targets in the design of subcritical systems). The LBE refers to a lead-bismuth eutectic alloy in which the mass percentages of lead and...
