Designer (requesting party): Westinghouse
Current positon: Assessment re-started in August 2014 following a pause. Westinghouse are now in the process of resolving outstanding issues before design acceptance can be granted.
You can make a comment about the AP1000 design via Westinghouse's website. Westinghouse will respond to the comments and issues raised.
At the end of each step of the assessment, the regulators publish detailed technical reports and a summary report.
A regulatory issue is a serious regulatory shortfall identified by the regulators. The issues are potentially significant enough to prevent provision of design acceptance. There are two regulatory issues published for the AP1000.
GDA issues remain following issue of interim design acceptance. They need to be resolved before a final design acceptance can be granted. There are currently 51 outstanding issues for the AP1000 and Westinghouse has published resolution plans for each issue.
In December 2011, ONR and the Environment Agency granted interim design acceptance to the AP1000 design.
