| Abstract Scope |
The Fukushima accident prompted a significant amount of work on developing advanced accident tolerant fuels for light water reactors. Through these campaigns a variety of different fuel forms have been developed and proposed such as UN, U3Si2, and UO2 with additives. While the thermophysical properties of these fuels are important in understanding the fuel performance, there is a need for mechanical properties of these advanced fuel forms to evaluate phenomenon like the pellet clad mechanical interaction during operation. Important mechanical properties that are needed of these advanced accident tolerant fuel forms are the elastic modulus, fracture properties and creep of the fuel at the operating temperature. In this work high temperature small scale mechanical testing and nanoindentation is performed on these accident tolerant fuels to measure the mechanical properties over temperature such as the elastic modulus, hardness, and fracture stress which will be discussed in the context of fuel performance. |
