【 摘 要 】

Gadolinium was mixed with uranium silicide in order to investigate the potential for its use as a burnable poison with a future Accident Tolerant Fuel (ATF) system. Three methods of manufacture were investigated, including two arc melting methods and powder blending. All methods failed to produce structurally robust pellets and were seen to produce inhomogeneous material consisting of multiple silicide phases. Of particular concern was the observation of uranium metal and (U,Gd)O-2 phases within the final material. (C) 2018 Elsevier B.V. All rights reserved.
