To ensure safe and reliable operation of the UK's Advanced Gas-Cooled Reactors (AGRs), seismic qualification of the graphite cores is required to demonstrate safe shut down during an infrequent seismic event. Seismic assessments of the AGR cores use a finite element modelling approach called GCORE.
The GCORE methodology has undergone validation based on dynamic response tests with small arrays of intact keyed bricks and static loading tests on large arrays containing simulated cracked bricks. To extend the validation of the GCORE methodology to the dynamic response of large arrays with cracked bricks, a shaking table experiment with a multi-layer keyed array (MLA) test rig with quarter-sized components based on late-in-life core geometry has been undertaken at the University of Bristol in collaboration with EDF Energy and Atkins.
