N2 - Investigating creep crack growth under extreme environmental conditions is a challenging yet essential undertaking for the assessment of structural lifetimes of critical components subjected to extreme working conditions for long periods of time. For example, there is currently a need to evaluate structural materials for Next Generation Nuclear Plants (NGNPs) which will operate very high temperature helium-cooled reactors (VHTRs) for generating electricity and co-generating hydrogen using the process heat from the reactor. The primary helium coolant is expected to operate at temperatures at or above 750°C. In order to evaluate candidate materials for the intermediate heat exchangers, such as Inconel 617 and Alloy 800H, we have developed a creep crack growth (CCG) test apparatus which was designed to test compact tension specimens at temperatures up to 850°C in controlled environments, including impure helium environments, following ASTM standard E 1457-07. Details of the design of the CCG apparatus will be discussed.
