The Advanced Gas Reactor (AGR) program is tasked with developing and qualifying fuel for the Next Generation Nuclear Plant (NGNP) [1, 2]. The first experiment, AGR-1, focused on TRISO coating 350 μm uranium oxide/uranium carbide (UCO) kernels and compacting them into a right circular cylinder fuel form using an overcoating and compacting process. The AGR-1 fuel compacts are currently being irradiated at the Advanced Test Reactor (ATR). The AGR-2 experiment will focus on overcoating and compacting TRISO coated 425 μm UCO kernels. This paper summaries the work that has been done to date on preparing to make AGR-2 compacts.
