Abstract Scope |
Molten Salt Reactors (MSRs) are being actively pursued as a next generation nuclear reactor
concept because of operational and safety qualities compared to other nuclear reactors.
Understanding the impact of microstructure on corrosion rates and the impact of elastic stress
on the corrosion behavior of structural alloys in a phase field model will aid the development of
corrosion-stress resistant alloys for molten salt reactors. This work models the corrosion
behavior of 316H by molten FLiNak and the impact of elastic stress at 973K by coupling an
electrochemical phase field model that predicts microstructure-dependent corrosion with a
mechanics model that represents the stress within the alloy. Once validated, we use the model to predict corrosion rates in structural alloys with internal stresses. |
