The graphite components in AGR cores are subject to degradation processes that are predicted to lead to greater numbers of weakened and cracked components. The reactor core models used to assess the tolerability of the cores to seismic events need to represent higher levels of degradation. A shaking table programme has commenced, with the primary goal to provide experimental validation of the existing AGR core models. This paper presents the proposed rig work with main aspects of physical model design, rig manufacturing and dynamic testing being addressed. The candidate instrumentation systems and the relevant rig outputs are also described.
