Quarterly Report published

This report provides an update on Hitachi-GE’s progress with GDA of the UK Advanced Boiling Water Reactor (UK ABWR), and the progress of Westinghouse’s AP1000 reactor design between February and April 2016.

UK ABWR & AP1000
 
 

UK ABWR

ONR continues its intensive assessment of the UK ABWR as it continues to progress through Step 4.  Our focus is to identify any further design changes and safety case developments to enable Hitachi-GE to address them within the current timescales.  The Environment Agency is continuing to carry out its assessments and is working towards beginning consultation on its findings so far later this year. Natural Resources Wales is also working towards this consultation.

AP1000

This period has seen an overall improvement in the Westinghouse approach to GDA closure, following executive level intervention. Westinghouse has revised and extended its schedule and it now seeks to complete GDA in March 2017.  The regulators remain concerned about the volume of work to be delivered and will conduct a detailed ‘health check’ this month to inform the level of confidence in the revised programme.


Get involved - We want you to understand what we are doing and why it is important. You can also ask a question and make comments on the designs of both reactors.

More information on GDA is available on the joint regulators' website.
