TL;DR: In this paper, the thermal-hydraulic safety margins of each transition cycle and state (i.e. beginning, middle and end) were evaluated. But, the authors did not consider the transition of the LEU fuel elements.

TL;DR: The contribution of stiffness from various components of the MITR LEU fuel element and DDE has not been determined so far as mentioned in this paper , but it is assumed that the bulk of the overall stiffness of the element is derived from swaging multiple fuel plates into the side plates.
Abstract: end fittings as well as of the entire fuel element is affected. The end fittings in the MITR LEU fuel element are designed primarily for proper handling and flow distribution. The stiffness of the end fittings also constitutes a fraction of the total stiffness of the entire fuel element. It is debatable to what extent the end fittings provide the structural rigidity necessary for the fuel element to properly respond to potential loadings. It is presumed that the bulk of the overall stiffness of the element is derived from swaging multiple fuel plates into the side plates. However, the contribution of stiffness from various components of the MITR LEU fuel element and MITR DDE has not been determined so far. The primary objective of the work presented in this report was to assess the extent to which the stiffness of the end fitting in the MITR DDE contributes to the stiffness of the entire fuel element, and how it compares to the equivalent stiffness of the end fitting in the MITR LEU fuel element. Several simplified load cases were analyzed for that purpose using the geometries of the MITR LEU fuel element, MITR DDE, as well as that of the MITR DDE without the top end fitting.

TL;DR: In this paper, the existence of a C14 variant, in parallel to the C15 phase, both dissolving uranium has been confirmed, which confirms the heuristic hypothesis of Stein (2011) about the stabilization of Laves variants depending on the crystallographic arguments.
