“…It is important to note that this layer is not designed to be a structural layer hence the reason it is an advanced TRISO rather than a quad-structural isotropic (QUADRISO) fuel or one with an additional ZrC barrier coating. QUADRISO fuel, developed by Argonne National Laboratory, has a fourth layer that is applied directly to the kernel that acts as a neutron absorption layer and can be either a burnable poison or a fertile neutron absorber (Talamo, 2010). The ZrC layer in this research is to be a sacrificial layer and is expected to degrade over time as the ZrC is transformed into ZrO 2 and free carbon, expressed by Eq.…”
