| Abstract Scope |
Corrosion of advanced materials exposed to high temperature helium is of interest for the future development of High Temperature Fission Reactors and Fusion Reactors where the operating conditions and lifespan of the components depend on the physical properties of the material and their ability to withstand high temperature exposure.
Helium is typically used due to the fact that it is “inert” and doesn’t become radioactive when exposed to neutron radiation. Complications within the system occur due to the presence of carbon (from graphite and other carbon sources within the system), impurities in the helium and also any water ingress from interfacing plant circuits. These factors, coupled with the very high temperatures of operation, can lead to very complex interactions taking place including oxidation, carburisation and decarburisation.
The work here has characterised advanced high temperature alloys relevant for use under high temperature conditions with advanced microscopy techniques (SEM, FIB and EDS). |
