ONR, the Environment Agency and Natural Resources Wales have today published their quarterly report on assessment of new nuclear power station designs. The report provides an update on the two designs currently going through the Generic Design Assessment (GDA) process, Hitachi-GE’s UK Advanced Boiling Water Reactor (UK ABWR), and the Westinghouse AP1000 reactor design, between November 2015 and January 2016.
In the report, we reference concerns with regards to the schedule for the GDA closure phase of the AP1000 design. Since the reporting period, Westinghouse issued a revised closure programme for GDA in response to our request. This schedule shows a projected GDA completion date of March 2017.
The regulators acknowledge the programme extension and will maintain a close focus on Westinghouse’s delivery and quality of submissions in the coming months. We will continue to provide our view of its progress in our future quarterly reports.
