Modelling electrical corrosion potential of 304 stainless steel under fusion power plant environment
2019
Predicting the electrical corrosion potential (ECP) of type 304 stainless steel, the structural material of recirculation pipes in fusion power plants, is important because the growth rate of intergranular stress corrosion crack (IGSCC) of 304 stainless steel is closely related to ECP. In this work, a new model has been developed, by modifying existing models, to calculate the ECP of recirculation pipes in future fusion power plant. The calculation results indicate that merely injecting hydrogen cannot reduce ECP below EIGSCC if the dose rate exceeds a threshold, other assisted water chemistry controlling method is necessary.
