摘要

•Time dependent surrogate model is generated for a Triga Mark II single fuel element.•Time dependent surrogate model is generated for a Triga Mark II single fuel element.•Errors are computed and reported to assess the surrogates.•DMD Surrogate is used for uncertainty propagation for a single fuel element.•Methodology is explored for full core 2-D assemblies, and difficulties were addressed.
