The Institute for Predictive Performance specializes in heterogeneous materials including: polymer, metal, and ceramic based composites for structural, electrochemical, chemical processing, nuclear fuels and nuclear waste storage, and chemical processing applications. Unique strengths include the development of special material analysis, characterization, and assessment methods that enable the prediction of future performance on the basis of current condition, including as-manufactured condition, for individual specimens, devices, structures, and systems. This is enabling technology for modern design and risk control methods such as supervisory control, zero maintenance, and certain nuclear nonproliferation strategies.
