title = "Preliminary Assessment of As-Built Design Characteristics for the Transformational Challenge Reactor",
abstract = "The Transformational Challenge Reactor design effort in 2021 included constructing a full-core mock-up of the reactor in-core components. This effort was undertaken to ascertain differences between the as-designed and as-built individual components and determine impacts of assembly of the as-built components into a full-scale core assembly. Through this effort, several deviations from as-designed components were observed. Some of these deviations were related to the additive manufacturing processes, and others were related to deviations in traditionally manufactured components. The tolerance stack-up of these minor deviations was evaluated and quantified. A new layered geometry capability in Shift (CAD + combinatorial) was used to model variations in the placement of YH moderator rods, and the effects of this variation on keff and power distribution are analyzed in this paper. Bison was used to model the thermomechanical effect of contact between adjacent fuel elements.",
