Abstract Scope |
FeCrAl alloys are currently being develop by General Electric Company [(GE) including GE Research, GE-Hitachi Nuclear Energy, and Global Nuclear Fuel (GNF)] as one of the promising concepts for Accident Tolerant Fuel (ATF) cladding in nuclear power reactors. Because the manufacturing of FeCrAl alloys involves a powder metallurgy process, subtractive machining of parts (such as fuel cladding end caps) can result in significant waste. Near net shape additive manufacturing can therefore provide the possibility of significant cost savings. The performance of additively manufactured parts, however, must show performance that is comparable to other manufacturing methods. We will discuss the effects of processing parameters on microstructure. The impact of this microstructure on performance testing of additively manufactured FeCrAl alloys during high temperature water autoclave testing and high temperature steam testing will also be discussed when compared to other manufacturing methods including wrought cast and forged FeCrAl alloys and Zr alloys. |
