The review of the applicability of submitted UK AP1000 design basis fault modelling to the GDA reference design

.1 ONR has already undertaken a comprehensive assessment of the adequacy of WEC’s extant UK transient analysis of design basis faults (Ref 1) against the 2006 ONR Safety Assessment Principles (SAPs). It is for WEC to propose a new design reference point, identify analysis appropriate for that design reference point (either new or existing analysis), justify why the analysis is appropriate for UK AP1000 design reference point, and comment on whether the “delta” is small enough such that ONR’s conclusions on the previous fault studies safety case submissions remain valid. 2.2 For this work package, a technical support contractor (TSC) is required to assist ONR by:  On a sampling basis, revi…
