The complex environmental conditions cladding and structural metals experience in current reactors and are expected to experience in proposed reactor designs makes it difficult to delineate active mechanisms resulting from each environmental factor and potential synergistic effects that may be present. Insight into these governing mechanisms is essential in the development of predictive multiscale models.
Sandia National Laboratories has developed an In-situ Ion Irradiation Transmission Electron Microscope. This facility permits real time nanoscale observation of the evolution of TEM samples, as a function of ion irradiation, gas implantation, mechanical loading, thermal annealing, exposure to corrosive environments, or various combinations thereof. Pure Ni, Fe, and a limited set of their alloys will be used as example systems to highlight the ability of this facility to deconvolute the role of various environments on the microstructural evolution, as well as inform advanced modeling efforts.
