Description
Technical Field

Background
Lead and lead-based alloys are widely used in the energy industry, such as accelerator-driven clean nuclear energy systems using lead-bismuth alloys as a coolant, lead-based cold fast reactors using lead or lead-bismuth alloys as a coolant, and fusion reactor concept studies using lithium-lead eutectic alloys as cladding materials. In the field of these lead and lead-based alloy reactors and the application of experimental loop systems, lead and lead-based alloys continue to corrode structural materials due to long-term operation of the coolant system, producing magnetic oxides or magnetic metals. These magnetic oxides or magnetic metals are easily deposited in the abrupt change position of the flow channel of equipment such as a valve, etc., or in the pipeline with low temperature and relatively low flow rate, so as to cause the blockage of the loop, or directly cause the damage of the equipment due to the attachment of impurities, thereby causing irreparable loss and great potential safety hazard to the reactor equipment and the loop system.
