| Abstract Scope |
Time-dependent material behavior like creep and creep-fatigue strength, corrosion rates, and radiation damage control the usefulness of potential high temperature reactor structural materials. Historically, time-dependent properties such as these have been determined via extensive long-term test campaigns with a limited amount of extrapolation in time. Qualifying new materials, therefore, is a lengthy and expensive process. New approaches such as advanced models with better accuracy for time extrapolation, staggered qualification approaches where long-term testing occurs as the material spends time in service, and approaches based on in-situ material surveillance are possible and would accelerate the qualification of new materials. This talk describes some of these approaches and analyzes their effectiveness using both historical data on already-qualified materials and data on new potential reactor materials, including material from additive manufacturing processes. |
