Design of online monitoring of wall material corrosion

The wall material of a tokamak is exposed to high radiation for a significant amount of time. Therefore, the most difficult problem in ensuring the safe operation of nuclear reactors is the design of a wall material that is conducive to the online monitoring of corrosion degree. In this study, we design an online detection system using isotope tracer technology to calibrate the corrosion degree of a tokamak wall material. Obtaining a sample with a gradient isotope is key for calibration systems. Therefore, we simulate the isotope behavior during ion implantation such that the appropriate injection parameters can be selected to obtain wall-material samples with a concentration gradient, thereby providing a theoretical basis for the corrosion degree calibration of wall materials.
