Twelve more issues closed on UK EPR reactor design

The Office for Nuclear Regulation (ONR) and the Environment Agency have closed 12 more ‘issues’ with the generic design of a nuclear reactor proposed for construction in the UK.

In December 2011, the regulators identified 31 issues on EDF Energy and Areva’s UK EPR design that must be addressed as a prerequisite to issuing final acceptance of the design.

The closure of the additional 12 issues, confirmed today through the publication of our letters to EDF Energy and Areva, brings the total number closed to 30, and leaves one outstanding.

[The 12 issues confirmed as closed today are the top 12 in this table.]

The remaining outstanding issue - GI-UKEPR-CC-02 - must be closed as a prerequisite to the regulators issuing a Design Acceptance Confirmation (in the case of the Office for Nuclear Regulation), or a Statement of Design Acceptability (in the case of the Environment Agency).
