With the increasing application of nuclear energy in power industry, China has accumulated a large amount of high‐level radioactive nuclear waste, which are characterized by high toxicity, high radioactivity, and long half‐life. Improper disposal will cause great harm to human life and property. China has decided to establish an underground laboratory for geological disposal of high‐level radioactive waste (HLW) in Beishan, Gansu Province, to study the scientific issues related to geological disposal of HLW. In this paper, an online monitoring system including two kinds of integrated inductance probe for the corrosion monitoring of metallic materials used in atmospheric or bentonite environment in Beishan underground laboratory was developed, and the reliability and accuracy of the system were studied. The results show that the system can satisfy the requirement of online monitoring of the corrosion rate of metallic materials, ambient temperature, resistivity, and humidity of bentonite in the underground laboratory for geological disposal of HLW in different environments.
