Description

technical field

[0001] The invention relates to the technical field of material corrosion protection research, in particular to a material corrosion simulation device for a cooling water system of nuclear island equipment and a method for using the same. Background technique

[0002] The cooling water system of the nuclear island equipment of the nuclear power plant provides cooling water for various safety-related and non-safety-related systems of the nuclear island. This system provides an intermediate barrier that can be supervised between the equipment containing radioactive fluid and the final heat sink. necessary system. Once the various heat exchangers in the system are fouled or clogged, the heat exchange efficiency will be seriously reduced, and material corrosion may cause equipment leakage to damage the barrier and even cause shutdown.

[0003] At present, there is a problem of excessive iron content in the equipment cooling water, which shows that the problem of...
