Abstract

Research into Accident Tolerant Fuels (ATF) in the wake of the Fukushima Daiichi Nuclear Disaster has precipitated interest in a diverse array of fuels and fuel combinations with favorable properties for accident tolerance. One such combination is the UN-U3Si2 system, which is purported to have favourable characteristics regarding thermal conductivity and water tolerance. In this paper, a ternary phase constituted by U-N-Si formed during SPS sintering is identified and characterized.
