Review of UK AP1000 Design Basis Fault Modelling for GDA Reference Design

About

The Department for Work and Pensions awarded a contract to GRS for a technical support contractor to assist the Office for Nuclear Regulation (ONR) in reviewing the applicability of submitted UK AP1000 design basis fault modelling to the GDA reference design.

The contractor will independently review new US transient analysis and differences from EDCD Rev 0/Rev 1 analyses on a sampling basis, assess the size of the delta and continuing applicability of ONR's regulatory conclusions, and evaluate WEC's justification for the continuing appropriateness of UK-specific analysis from GDA Steps 3 and 4.

The work involves faults from Chapter 15, containment analysis in Chapter 9, and shutdown faults in Chapter 19E, with additional information obtainable via the Regulatory Query process.

The contract value is AUD 79,550.
