NSUF 11-284: Corrosion Test in Supercritical Water for Nitride-based Coatings on LWR Cladding

We propose to conduct a series of corrosion tests under supercritical water conditions for nitride coatings on Zircaloy claddings. The nitride coatings will be coated on the outer surface of the Zircaloy cladding tubes and used as corrosion resistance layer for the cladding against corrosion and crud deposition in light water reactors (LWR). This project is a collaborative effort between Dr. Haiyan Wang at Texas A&M University (TAMU) and Dr. Hongbin Zhang and Dr. Jian Gan at Idaho National Laboratory (INL). The coatings will be deposited and tested at TAMU. However at TAMU, such corrosion test station under supercritical water conditions is currently not available. Therefore the access to the corrosion testing facility in ATR National Scientific User Facility is critical to the success of the joint project. We propose a 30-day access to the corrosion testing facility and conduct a set of experiments on the ziraloy bars with and without nitride coatings (see details in experimental section). The understanding on the corrosion resistance of the coating against supercritical water environments as functions of coating thickness and grain size will be very valuable for future implementation of corrosion resistive coatings on Zircaloy cladding tubes for LWR.
