| Abstract Scope |
Microreactors are currently of interest to the nuclear energy field as a means to provide ‘portable’ power. In order to make these reactors inherently safe, a coreblock is used to provide structural stability. Current coreblock solutions (ex. steels) limit operating temperatures to 600-700°C. The use of titanium – zirconium – molybdenum (TZM) alloys could allow for a substantial increase (2-3X) in operating temperature and, thereby, increasing energy output. Notably, TZM is difficult to form, machine and join. Hence, we are looking at additive manufacturing (AM) as a method to create near-net-shape components with complex geometries. Literature on AM of TZM is available indicating that densities of 99.7% have been achieved. In this work we aim to improve upon this density through a concerted process parameter development effort coupled with mechanical testing in order to identify process-structure-property relationships optimized for nuclear energy applications. |
