Description

technical field [0001] The invention belongs to the technical field of nuclear engineering, and in particular relates to a device and a method for adjusting the oxygen concentration in a liquid lead-bismuth alloy by using solid lead oxide. Background technique [0002] Liquid lead or lead-bismuth alloy (LBE) is the material of choice for primary high-energy hash targets in accelerator-driven subcritical systems (ADS) and an important candidate material for coolants in advanced reactors. But its corrosion to structural steel has become the biggest obstacle to its wide application. At present, oxygen concentration control technology is generally considered to be the most effective LBE anticorrosion method. Almost all existing international experimental benches adjust the oxygen content in LBE by injecting low concentration of oxygen or hydrogen into the liquid metal or the covering gas on its surface, but this gaseous oxygen concentration control method has many shortcomings....
