An understanding of the behaviour of radially-keyed graphite cores and the internal stress and deformation of individual core components under normal operation and transient conditions is essential in assessing core geometry, component integrity, inspection strategy and consequently core integrity. When assessing graphite core integrity an in-depth understanding of the broad range of material and physical behaviours of the core during steady-state, transients and fault conditions is essential. This paper describes recent advances in the approach developed to assess Magnox reactor core structural integrity, which is one of the legs comprising a graphite core safety case, the other legs being inspection, monitoring and consequences.
